Enrich by APN

Look up properties by Assessor's Parcel Number (APN). Each item in the data array provides an apn, and the API normalizes formatting automatically (dashes, spaces, dots are all handled). Optionally include a location to narrow results to a specific area.

Each request accepts up to 250 items in the data array. The response returns every submitted item with a matched flag indicating whether a property was found.

Body Parameters

body dataarrayrequired

Array of APN objects to look up (max 250).

APN object properties

body apnstringrequired

Assessor's Parcel Number (e.g., "0123-45-6789"). Formatting varies by county — the API normalizes to the raw unformatted form automatically.

body locationobject

Location to narrow results to a specific area. When omitted, results are not filtered by location.

Location object properties

body typestringrequired

Location type: "state", "zip_code", or "county".

body codestringrequired

Location code. For states, use the 2-letter abbreviation (e.g., "TX"). For ZIP codes, use the 5-digit code (e.g., "78704"). For counties, use the FIPS code (e.g., "48453").

body fieldsstring[]

Field IDs to include in results. Can include both property and people fields. Omit or pass an empty array for the default set.

body contact_audiencestring

Which contacts to include on matched properties.

Options: owners, owners_and_family, renters, residents, none

Use none or omit this parameter to return property data without contacts or people data credit charges. Any other value includes a contacts array.

Response Fields

The response contains a data array and a totals object. There is no pagination — all submitted items are returned in a single response.

Matched Result

When matched is true, the result contains all always-included property fields plus any requested fields.

Field	Type	Description
`input`	object	Echo of the original input object
`matched`	boolean	`true`
`dm_property_id`	string	DealMachine internal property ID
`full_address`	string	Complete formatted address
`address`, `city`, `state`, `zip`	string	Parsed address components
`latitude`, `longitude`	number	Property coordinates
`images`	object	Signed URLs for `street_view`, `satellite`, and `roadmap`
`contacts`	array	Contacts matching `contact_audience`. Omitted when the audience is `none` or not set.
requested fields	varies	Any fields specified in `fields`

Unmatched Result

Field	Type	Description
`input`	object	Echo of the original input object
`matched`	boolean	`false`
`match_failure`	object	Structured failure with `code` and `reason`
`match_failure.code`	string	Machine-readable failure code (see Match Failure Codes below)
`match_failure.reason`	string	Human-readable explanation of why no match was found

Match Failure Codes

These codes are shared across all enrichment endpoints.

Code	Description
`not_found`	No matching record exists for the provided input
`invalid_input`	The input could not be processed (e.g., invalid address, invalid email, invalid phone number). The `reason` field provides specifics.

Totals

Field	Type	Description
`submitted`	integer	Number of items in the request `data` array
`matched`	integer	Number of items that matched a property
`unmatched`	integer	Number of items that did not match

Credits

This endpoint consumes 1 property data credit per matched property. A non-none contact_audience adds people data credits for included contacts. Use none for zero people data credits. Only matched results consume credits. Credits are deduplicated within your billing period, so accessing the same entity again is free.

Every response includes a credits object with a full breakdown of what was charged. See Credits for details.

Notes

Each item only requires the apn field. The API normalizes formatting (dashes, dots, spaces) to the raw unformatted form automatically.
The location parameter is optional. When provided, results are scoped to that area. When omitted, the search is nationwide.
Items are matched independently — one failed match does not affect others.
The input object is always echoed back so you can correlate results with your input data.
When contact_audience is set to an audience other than none, each matched result includes a contacts array with the same structure and match behavior as Search Properties.
