For business verification only. TradesAPI is not a consumer reporting agency. May not be used for employment, credit, insurance, tenant screening, or any other purpose governed by the Fair Credit Reporting Act.

What we do

Four primitives, one normalized API.

One normalized schema.

{valid, name, status, expiration, disciplinary_actions, source_url, ...} — same shape whether you're hitting Texas TDLR, California CSLB, or New York DOS. Your integration code doesn't change per state.

Batch up to 200 licenses per call.

Parallelized against live state portals, single response. Credit deduction is atomic and positional — no partial charges if a single lookup fails.

Name search across 33 states.

Fuzzy match when your customer only has a contractor name. Results include all matches with full license metadata.

MCP-ready out of the box.

Hosted endpoint at /mcp plus an npm client for Claude, Cursor, OpenAI, and any MCP-speaking agent. OAuth 2.1 with browser flow — no API keys in config files.

Why partners choose us

Clean scope. Live data. Nothing to maintain.

Built for embedding, not reselling.

License verification only. We'll never do insurance, COI, or KYC. That means we'll never compete with the product you're building on top of us.

Real-time, not nightly.

Every call hits the state portal live. No stale cached data, no missed revocations. Your compliance team sees what the state sees.

Self-healing infrastructure.

Automated health probes every 15 minutes. When a portal changes, a repair pipeline diagnoses the break and ships a fix — with no human in the loop. Maintenance cost you don't pay.

Operational transparency

We don't publish uptime claims we haven't measured.

Instead, here's what we expose publicly so you can check for yourself:
