Getting Started
Welcome to the HouseCanary Analytics API! You can use the HouseCanary Analytics API to access HouseCanary’s proprietary analytics as well as public records data.
Integrating is quick and easy. We provide a Python API Client as well as sample code in popular languages. Our Match and Append app lets you use a spreadsheet to access HouseCanary data - no developer time required!
Making Requests
URL structure
The HouseCanary API is based on REST.
Each request URL has a form: {BASE}/{ENDPOINT}
The base URL of the API is https://api.housecanary.com/v2
Each endpoint follows the form: {LEVEL}/{TARGET} where {LEVEL} is one of:
| Level | Description |
|---|---|
| property | Individual property: a building or a unit within a building |
| block | US-census block |
| blockgroup | US-census block group |
| zip | US zipcode |
| metrodiv | US-census Metropolitan Division |
| msa | US-census Metropolitan Statistical Area |
| state | US State |
and {TARGET} is the data descriptor such as value, rental_value, details, etc.
Example: https://api.housecanary.com/v2/property/value has the level property, and a target of value, which comprise an endpoint property/value.
Requests
Each request URL allows accessing data for items that belong to the URL’s level. Items can be specified by these identifiers.
- Data for a single item can be retrieved with a GET request by specifying item identifiers in the query string.
- Data for multiple items can be retrieved in bulk using a single POST request by specifying a sequence of item identifiers in the JSON-encoded body.
In both cases, the requested items are always members of the same level, that of the URL.
Responses
The responses to both GET and POST requests are JSON arrays representing the sequence of data chunks, one chunk for each requested item, preserving the request sequence order:
- A response to the GET request will contain a single chunk, because the single item was requested.
- A response to the POST request will contain as many chunks as there were items in the requested sequence.
Authentication
In order to use the HouseCanary API, you must obtain a credentials pair (API Key, API Secret) from your settings page.
Authentication of API requests is made using HTTP Basic Authentication. Use your API Key as the user name and your API Secret as the password for Basic Authentication. HTTPS must be used for all API requests. See the full request examples below that show how to authenticate with the API in various programming languages.
For Authentication failure information, see here.
Test Credentials
Test credentials are useful for verifying functionality in a development or staging environment. In order to generate test credentials (API Key, API Secret), go to your settings page and use the “New Test API Key” link.
Your test credentials can be used to make test requests. The HouseCanary API maintains a whitelist of items that can be used in test requests. For more information on retrieving this whitelist, see here.
Permissions
To access the API, the user account associated with your authentication credentials must have permissions enabled for all API components you are trying to call. You can see which components you have enabled in the “Analytics API” section of API settings. Contact support if you have questions about the components you have access to.
Levels and Identifiers
Depending on the level of the URL, different identifiers have to be used to specify the items of interest. For example, properties are identified by their addresses, while residential blocks are identified by their census block IDs.
| Level | Possible Identifiers |
|---|---|
| property | any combination of address, unit, state, city, zipcode that identifies the US address. Usually this is address and zipcode or address, city, state. |
| property | slug |
| block | block_id |
| blockgroup | blockgroup_id |
| zip | zipcode |
| metrodiv | metrodiv |
| msa | msa |
| state | state |
All possible identifiers are defined below. Same identifiers can be used in the query string parameters for GET requests and input sequence items in the body for POST requests.
| Identifier | Description | Example |
|---|---|---|
| address | Building number, street name, and optionally unit number | "123 Main St" |
| unit | Unit number for the property, if needed and not already specified in the address string | "Unit 3" |
| city | City for the property | "San Francisco" |
| state | 2-letter acronym of the US state | "CA" |
| zipcode | Zipcode for the property | "94105" |
| slug | A single URL-safe string identifying the address (obtained from HouseCanary) | "123-Example-St-San-Francisco-CA-94105" |
| block_id | 15-digit census block ID | "060750615003005" |
| blockgroup_id | 12-digit census block group ID | "060750615003" |
| metrodiv | 5-digit Metropolitan Division ID | "41884" |
| msa | 5-digit Metropolitan Statistical Area ID | "41860" |
GET Requests
Using a GET request, you can retrieve data for a single item from an endpoint by specifying item identifiers in the query parameters.
GET URL Format
Example GET URLs:
https://api.housecanary.com/v2/property/geocode?address=10216+N+Willow+Ave&zipcode=64157
https://api.housecanary.com/v2/property/value?address=10216+N+Willow+Ave&zipcode=64157
https://api.housecanary.com/v2/property/value?address=65239+Rosanne+Prairie+St&city=Bayardchester&state=CA
https://api.housecanary.com/v2/property/rental_value?slug=65239-Rosanne-Prairie-Bayardchester-CA-90113
https://api.housecanary.com/v2/block/value_distribution?block_id=012345678901234
https://api.housecanary.com/v2/zip/details?zipcode=01234
https://api.housecanary.com/v2/msa/hpi_ts?msa=09876
GET https://api.housecanary.com/v2/{ENDPOINT}?{IDENTIFIERS}
{ENDPOINT} is the specific endpoint you are calling, such as property/value. See all available endpoints.
{IDENTIFIERS} is the URL-encoded string providing item identifiers as an ampersand-separated list of key=value pairs.
Exact identifiers depend on the level of the URL, see Levels and Identifiers.
Example URL separated into constituent segments:
{BASE}: https://api.housecanary.com/v2
{ENDPOINT}: zip/details
{IDENTIFIERS}: zipcode=01234
Then, combined together:
{BASE}/{ENDPOINT}?{IDENTIFIERS}:
https://api.housecanary.com/v2/zip/details?zipcode=01234

POST Requests
Using a POST request, you can retrieve data for multiple items by specifying a sequence of item identifiers in the POST body. We strongly recommend using POST requests for batching whenever possible.
POST URL Format
Example POST URL format:
https://api.housecanary.com/v2/property/geocode
https://api.housecanary.com/v2/property/component_mget?components=property/details,property/value
POST https://api.housecanary.com/v2/{ENDPOINT}
{ENDPOINT} is the specific endpoint you are calling, such as property/geocode. See all available endpoints.
POST Body
Example POST body:
[
{
"address": "10216 N Willow Ave",
"zipcode": "64157"
},
{
"address": "34813 SE Burrows Way",
"zipcode": "98065"
}
]
All POST requests must have the Content-Type header set to application/json and the POST body must be a valid json array representing a sequence of requested item identifiers.
There is a limit of 100 items per POST request (i.e. 100 address + zipcode combinations, or 100 block_ids).
All items in a single POST request must have the same set of keys. For property-level POST requests, eitheraddress or slug keys must be present for all items so HouseCanary can identify the specific properties.
Each item in the json array must contain one or more of the following keys:
| Level | Key | Required? | Description | Value Example |
|---|---|---|---|---|
| property | address | No | Building number, street name, and optionally unit number | "123 Main St" |
| property | unit | No | Unit number for the property, if needed and not already specified in the address string | "Unit 3" |
| property | city | No | City for the property | "San Francisco" |
| property | state | No | Either the full name or a 2-letter acronym of the US state | "CA" |
| property | zipcode | No | 5-digit ZIP code for the property | "94105" |
| property | slug | No | A single URL-safe string identifying the address (obtained from HouseCanary) | "123-Example-St-San-Francisco-CA-94105" |
| block | block_id | Yes | 15-digit census block ID | "060750615003005" |
| blockgroup | blockgroup_id | Yes | 12-digit census block ID | "060750615003" |
| zipcode | zipcode | Yes | 5-digit ZIP code | "94105" |
| metrodiv | metrodiv | Yes | 5-digit Metropolitan Division ID | "41884" |
| msa | msa | Yes | 5-digit MSA ID | "41860" |
| state | state | Yes | Either the full name or a 2-letter acronym of the US state | "CA" |
| any level | meta | No | A purely optional key whose value is an arbitrary string that gets returned along with the item in the response. Use this if desired for client-side item references, descriptions, etc. | "1" |

Rate Limits
Rate limit response (headers truncated):
HTTP/1.1 429 TOO MANY REQUESTS
Date: Fri, 04 May 2018 19:28:19 GMT
Content-Type: application/json
X-RateLimit-Remaining: 0
X-RateLimit-Limit: 250
X-RateLimit-Period: 60
X-RateLimit-Reset: 1525462154
{
"message": "Too Many Requests"
}
There are limits on how many API requests can be made in a certain period of time. You can see rate limits for your account in API Settings.
| Endpoints | Rate limit for self-serve customers | Rate limit for enterprise customers |
|---|---|---|
| Analytics API | 250 components per minute | |
| Value Report | 10 requests per minute | |
| Rental Report | 10 requests per minute | |
| Value Analysis | 10 requests per minute |
Rate limits differ between the Analytics API endpoints and the Value Report endpoints. Rate limits for the Analytics API are counted by the number of components called. One component is the combination of a specific endpoint with an address or other geographic level identifier. Value Report, Rental Report, and Value Analysis are rate limited based on number of HTTP requests in the time period.
How different Analytics API requests count against the component rate limit:
- GET
property/geocode- 1 endpoint
- Only accepts 1 address
- Counts as 1 component against the rate limit
- GET
property/component_mgetwith 2 endpoints specified- 2 endpoints
- Only accepts 1 address
- Counts as 2 components against the rate limit
- POST
property/geocodewith 3 addresses in the body- 1 endpoint
- 3 addresses in the body
- Counts as 3 components against the rate limit
- POST
property/component_mgetwith 4 endpoints specified and 4 addresses in the body- 4 endpoints
- 4 addresses in the body
- Counts as 16 components against the rate limit
Custom response headers are returned from the API to indicate rate limit information:
| Header Name | Description | Example Value |
|---|---|---|
| X-RateLimit-Period | Comma separated values that define the rate limit windows, in seconds | 60 |
| X-RateLimit-Limit | Comma separated values that define the number of components or requests the consumer is permitted to make for each rate limit window | 250 |
| X-RateLimit-Remaining | Comma separated values that indicate the number of components or requests remaining for each rate limit window | 248 |
| X-RateLimit-Reset | Comma separated values that indicate the time at which each rate limit window resets in UTC epoch seconds | 1525368621 |
Security
TLS 1.0, 1.1 and 1.2 are supported. SSL is not supported.

Detailed data related to estimated loan-to-value ratio (LTV). This endpoint itemizes each lien determined to be active on the property and provides details for each on grantors, grantees, monthly payment, current interest rate, original lien amount, length, months completed, outstanding principal, principal paid, record date, due date, ARM details, and more. This endpoint also provides summary data on totals of equity, monthly payments, lien amount, and notice IDs, as well as property valuation.
Liens determined to be active have pay down calculated per available lien terms, utilizing information including ARM details and interest-only periods where applicable and available. A sorted list of notice IDs are also included in the response, and their corresponding descriptions are available below. These state any findings during the LTV generation and their typical impact on the calculation - the recipient of this response is free to interpret these notices with higher or lower severity given their own knowledge and context. Missing or malformed public record data requires assumptions to be made.

Analytics API: cross-level
Overview
Cross-level is a way of accessing non-property level data through property identifiers. It is handy if you want to get block rental indices or zip details and so on, for the location of a given property, while avoiding multiple API calls.
Rules
All of the block/zip/msa level data can be also obtained through the property-level endpoints. If this is desired, the cross-level endpoint corresponding to the
{ORIGINAL_LEVEL}/{ORIGINAL_TARGET}
would be
property/{ORIGINAL_LEVEL}_{ORIGINAL_TARGET}
where {ORIGINAL_LEVEL} is one of: block, zip, msa.
In other words, one can make a cross-level URL from any other URL by changing level
to property and prepending the original target with the original level and an underscore.
For example,
/property/block_value_distribution?slug=65239-Rosanne-Prairie-Bayardchester-CA-90113
fetches the same data as
/block/value_distribution?block_id=012345678901234
assuming that the property 65239-Rosanne-Prairie-Bayardchester-CA-90113 is located in the census block 012345678901234.
Rationale
If you have a property address at hand you could either:
- call
property/geocodeendpoint on the addresses to find out block ID and/or zipcode and/or MSA, and then callblock/{TARGET}orzip/{TARGET}ormsa/{TARGET}endpoints; - or you can call
property/block_{TARGET}orproperty/zip_{TARGET}orproperty/msa_{TARGET}on the addresses.
Your choice depends on whether you are requesting multiple addresses and how they are spread across blocks/zipcodes/msa and also on the convenience vs cost considerations.
For example, if you have 100 addresses at hand and those addresses are all located
within 2 blocks, it is more efficient to make 1 call to property/geocode on those addresses
to determine block IDs, and then make 1 call to the block-level endpoint of interest with the 2 block IDs.
This might be less convenient for you, if you have to then match the 2 block-level responses to
your 100 original properties. On the other hand, the more convenient way of calling the
cross-level URL with the 100 addresses will fetch you largely duplicate data and might
incur larger usage charges, depending on the pricing structure.

Response Codes and Errors
The HouseCanary API is built leveraging the REST paradigm. Under normal conditions, the API will return a response with a 200 OK HTTP status code. If an error occurs, the response will contain the appropriate HTTP status code as described below.
API Code and API Code Description
Example response body with a business logic error due to an invalid zipcode
[
{
"address_info":{
"city":null,
"county_fips":null,
"geo_precision":"unknown",
"block_id":null,
"zipcode":"00000",
"address_full":"34813 Se Burrows Way 00000 00000",
"state":null,
"unit":null,
"address":"34813 Se Burrows Way 00000",
"lat":null,
"lng":null,
"slug":null,
"zipcode_plus4":null
},
"property/value":{
"api_code_description":"no content",
"api_code":204,
"result":null
}
}
]
Because a single request can include multiple items or multiple endpoints, each response section returned in a normal 200 response will contain its own api_code and api_code_description fields. These are used to identify business logic errors for those items. The following values may be returned:
| API Code | API Code Description | Meaning |
|---|---|---|
| 0 | ok | Successfully retrieved data for the item |
| 204 | no content | Unable to retrieve data for the item |
We do not charge for sections returned with a 204 api_code.
400 - Missing required fields or incorrect request structure
Example 400 response body:
{
"message": {
"address": "Missing required parameter in the query string"
}
}
If one or more required fields for an endpoint are missing in the request, a 400 Bad Request status code will be returned, and the response body will contain an explanation of the error.
A common reason for a 400 response is missing required query parameters.
We do not charge for requests that result in a response with a 400 status code.
401 - Authentication failure
Example 401 response body:
{
"message": "Authentication Failed",
"code": 401
}
In the case of authentication failure, a 401 Unauthorized status code will be returned.
Note: In the case of an authentication failure, the system will return a 401 without any explanation or description. Should you have any questions on an auth failure, please contact HouseCanary technical support.
We do not charge for requests that result in a response with a 401 status code.
429 - Rate limit hit
Example 429 response headers and body when your organization has hit the rate limit for component requests (headers truncated):
HTTP/1.1 429 TOO MANY REQUESTS
Date: Fri, 04 May 2018 19:28:19 GMT
Content-Type: application/json
X-RateLimit-Remaining: 0
X-RateLimit-Limit: 250
X-RateLimit-Period: 60
X-RateLimit-Reset: 1525462154
{
"message": "Too Many Requests"
}
If your organization has made all the component requests allowed under your organization’s rate limit,
a 429 Too Many Requests status code will be returned, and the response body will contain the message shown to the right. If you run into this error, you must wait until the UTC epoch time returned in the X-RateLimit-Reset header. If you need a large volume of data, HouseCanary is able to support significantly higher rate limits for enterprise customers. Contact us for more details.
We do not charge for requests that result in a response with a 429 status code.
API Clients
Python API Client
The Python API Client makes it easy for you to interact with the HouseCanary API without manually writing HTTP request code. Client libraries for more programming languages are coming soon.
Match & Append
HouseCanary’s Match and Append app lets you get data for specific properties using only a spreadsheet - zero programming required. It’s included free with all API subscriptions.
Changelog
August 31, 2019: Deprecation of following endpoints
- property/rental_yield
- property/on_market
- property/rental_on_market
- property/value_by_quality
July 18, 2018: Value Report endpoint changes
We’ve added two new endpoints to make it easier for you to get the right version of Value Report:
- property/value_report_static_link returns a link to a PDF version of the Value Report for the property.
- property/value_report_dynamic_link returns a link to the interactive web version of Value Report for the property where you can view photos and choose comps.
These new endpoints are also more consistent with the rest of the API, which should simplify your integrations.
We’re deprecating the legacy property/value_report endpoint in favor of the new ones - it will not be available after September 30, 2018.
July 17, 2018: Sorting and filtering for chronological endpoints
Endpoints that return lists of time-separated items (liens, sales, disasters, etc) now support optional parameters that make it easier to get exactly what you need, in the order you need it.
- Need the last two years of tax data?
property/tax_history?order=desc&limit=2 - Just want the latest sale for a property?
property/sales_history?order=desc&limit=1 - Only need liens originated before 2015?
property/mortgage_lien_all?order=desc&end=2015-01-01
The new parameters are:
- order: Chronological order to sort result items. One of [
ascordesc]. Defaults toasc. - limit: Maximum integer number of result items to return. Defaults to
null. - start: Beginning date limit for result items, in ISO 8601 format, i.e.
2015-01-01. Defaults tonull. - end: Ending date limit for result items, in ISO 8601 format, i.e.
2015-01-01. Defaults tonull.
You can use the new parameters with the following endpoints:
- property/fema_disaster_area
- property/mortgage_lien
- property/mortgage_lien_all
- property/nod
- property/sales_history
- property/tax_history
- All timeseries endpoints (anything with
_tsin the name)
June 27, 2018: property/tax_history
property/tax_history provides historical assessment data, useful for tax grievance.
June 8, 2018: property/land_value
The new property/land_value endpoint lets you see the value of the actual land a property sits on, so you can understand how the land and improvements on it compare to make up the total sale AVM.
May 22, 2018: Update to property/listing_status
Now when you query the property/listing_status endpoint, recently sold properties will return a Sold value for a short period of time after the sale. Previously, those properties would appear as Not Listed.
May 15, 2018: property/fema_disaster_area
The new property/fema_disaster_area endpoint lets you check whether a property in a federally-declared disaster area. FEMA declarations can mean federal aid is coming to an area, and can affect loan origination.
May 10, 2018: Rental price index endpoints, added room_types to property/details_enhanced
We’ve added a number of new endpoints exposing analytics derived from our rental price index:
- property/rental_value_forecast
- zip/rpi_forecast
- zip/rpi_historical
- zip/rpi_ts_forecast
- zip/rpi_ts_historical
- msa/rpi_ts_forecast
- msa/rpi_ts_historical
- state/rpi_ts_forecast
- state/rpi_ts_historical
property/details_enhanced now includes a room_types field with descriptions of different rooms in the property.
January 25, 2018: property/value_details_adjusted
The new property/value_details_adjusted endpoint lets you see how the value of a property would change if more bedrooms, bathrooms, square footage, and/or a pool were added.
January 8, 2018: property/listing_status, address matching, new test addresses, zip/details changes
The new property/listing-status endpoint lets you check whether a property is listed for sale (and property/rental-listing-status) does the same for rental).
All API responses now include details on how the requested address was matched (or not) to an address in HouseCanary’s systems. If you’re not sure about an address you’re investigating, the status section will let you know if it’s a good address, missing a unit number, or just plain wrong - all for free. Check out the property/geocode docs for details.
We’ve updated the list of test properties - we increased it from 10 to 100, for complete nationwide coverage.
ZIP-level forecast data is now available in zip/hpi_forecast, rather than zip/details.
October 6, 2017: New pricing, free trial, new endpoints
We’ve updated our pricing for the HouseCanary API - it’s simpler to understand, and we’ve significantly lowered the price of some of our most-used endpoints. Along with the update, we’re offering $200 of free API credit to new and existing customers. New customers automatically get the credit when they sign up. Existing API customers can contact HouseCanary support to receive the credit.
We’re also excited to announce new endpoints, available now for users on the new pricing plan.
- property/valuation_analysis/check
- block/crime
- block/hazard_earthquake
- block/hazard_hail
- block/hazard_hurricane
- block/hazard_tornado
- block/hazard_wind
