The same desk, as an API.

Every lookup on this site is a REST endpoint: businesses, people, filings, watches, ZIP profiles and calling hours. JSON in, records out — with the same masking and compliance rules as the app.

• 1 key every record type
• OpenAPI spec + Markdown docs
• RFC 9457 problem+json errors with a correlation id
• Idempotent mutating calls replay safely

Predictable, from the first call to production.

• One key, every record — Businesses, people, filings, watches, ZIP profiles and calling hours behind the same org-scoped key.
• Errors you can act on — Every error is problem+json with a stable code and a correlation id you can hand to support.
• Masking built in — Free-tier results come back masked with a machine-readable envelope, so your client knows exactly what it can show.
• Safe to retry — Mutating calls carry an idempotency key. Replay a request and get the same result, never a duplicate.

Three calls to production.

1. Create a key — Org-scoped keys from the API hub. Rotate or revoke any time; usage is logged per key.
2. Make the call — Try it in the in-app tester first, then copy the curl. Responses are plain JSON with dated facts.
3. Go to production — Webhooks for watches, bulk endpoints for lists, and rate limits published in the docs.
