Public Records API — MPP Machine Payments

Business entity and UCC filings, county property records, and property deed and lien records through one MPP-payable API.

The MPP Public Records Gateway gives agents and applications one paid API for three normalized public-record services. Indexed jurisdictions answer instantly. For broader jurisdiction coverage, submit a job and collect results within minutes.

How access and payment work

Instant GET routes return records in one request for the indexed jurisdictions listed below. Full-coverage work uses POST /{service}/jobs: submission and status polling are free, results are normally ready within minutes, and only GET /jobs/{job_id}/result is paid.

Paid responses use the Machine Payments Protocol (MPP) over HTTP 402 Payment Required. The challenge provides the authoritative runtime quote. Stablecoin payments support quotes from the $0.01 floor; card payment is offered for quotes of $0.50 or more. Pricing is generally per delivered record. Failed and empty job results are not challenged for payment.

For a full-coverage job:

  1. Submit POST /entity/jobs, POST /parcel/jobs, or POST /deed/jobs with JSON input. Send X-Client-Id for a separate concurrency allowance.
  2. Poll GET /jobs/{job_id} until it reports success and a record_count.
  3. Collect and pay for delivered records at GET /jobs/{job_id}/result.
