Quickstart

Get your first API response in under a minute. All you need is curl (or any HTTP client).

1. Make a request

Every data endpoint follows the same pattern:

GET /{vertical}?jurisdiction={city}&limit={n}

For example, fetch five building permits from Austin, TX:

curl -H "X-API-Key: YOUR_KEY" \
  "https://api.threshmoor.com/permits?jurisdiction=austin&limit=5"

Available endpoints

The same pattern works across all five data verticals:

Endpoint	Data	Filter param
`/permits`	Building & construction permits	`permit_type`
`/violations`	Code enforcement violations	`violation_type`
`/landuse`	Land development & zoning applications	`case_type`
`/businesses`	Business licenses & registrations	`business_type`
`/property`	Property transfers & assessments	`property_type`

Every endpoint also accepts jurisdiction and limit (1–100, default 25).

2. Read the response

The API returns a JSON object containing the jurisdiction name, a count, and an array of records. Every record in a given vertical follows the same schema regardless of source.

Example response from /permits (truncated to two records):
