General Contractor license verification API
Developer needs to confirm a general contractor holds a valid, active license before onboarding them. One REST endpoint across every U.S. state board. Confirm a contractor, nurse, or real-estate agent is licensed, active, and in good standing, without scraping portals or wiring up each state by hand.
$9 fully refundable · locks founder pricing · no charge until launch beyond the reservation
Pre-launch: the API is in private testing. Reserve to lock founder pricing and help shape coverage.
GET /v1/licenses/verify?profession=contractor&state=CA&license_number=... # sample curl https://api.credentry.dev/v1/licenses/verify \ -H "Authorization: Bearer $CREDENTRY_KEY" \ -d state=CA \ -d profession=contractor \ -d license_number=1043587
One schema, every board
50 states, hundreds of professions, normalized into one response. Status, expiry, disciplinary flags, and the raw source record.
Always current
Licenses expire and get revoked. We re-check against the source board so a stale cache never clears someone who shouldn't pass.
Built for the hiring flow
Sub-second verify, webhooks on status change, and a bulk endpoint for re-screening your whole roster on a schedule.
The API
One request in, one JSON response out.
Authenticate with a bearer token and send one request. Everything is versioned under /v1, so a breaking change always ships behind a new version, never under you.

Who it's for
Teams who would rather call an API than build and maintain this in-house. The biggest platforms may have rolled their own. Everyone else is stuck choosing between brittle scrapers, stale exports, and manual checks.
- Marketplaces hiring licensed pros (home services, healthcare staffing, legal)
- Background-check and screening platforms
- Insurers and lenders underwriting licensed businesses
- Compliance teams re-verifying rosters on a schedule

Questions
Where does the data come from?
Public state licensing-board records. We normalize each board's format into one consistent schema and timestamp every lookup.
How fresh is it?
Verifications hit the source board so you get live status, not a stale export. Cached reads are clearly dated.
Which professions are covered?
Contractors and the skilled trades first (electrician, plumber, HVAC, roofing), then healthcare, real estate, and cosmetology. Tell us which you need.
What does the $9 reservation get me?
It locks your spot in the first cohort, founder pricing for 12 months, and priority on the professions and states you need. Fully refundable, anytime, no questions.
Who's building this
Micah Manzano, founder of Manzano Labs
I build the boring-but-critical plumbing so your team does not have to. Before this I built and shipped Nooma, an AI reporting platform used by marketing agencies, so I know what it takes to ship and keep real software running. Credentry exists because I kept watching teams rebuild the same data plumbing from scratch.
I work hands-on with developers and care about one thing: removing the friction between you and the data you need. Email me directly at hello@manzanolabs.com. I read every one.
Shape the roadmap
Building this with the developers who'll use it.
What would make Credentry an instant yes for you? Which states, lists, fields, or endpoints do you need first? Tell me and I'll build toward it. Every reply shapes what ships.
Reserve your key
$9, fully refundable. It tells us you're real and locks your founder rate. We build toward the first cohort's exact needs.
