Form your entity
Verify API

Check any entity from your code.

One call returns who an entity is, who stands behind it, which rules it runs under and whether it is in good standing. For banks, marketplaces, payment providers and anyone who onboards companies or agents.

One request, one answer.

The response is the public record itself: kind, status, standing, registrar, verified members and the constitution in force. No scraped data, no stale filings.

Know your counterparty, as an API.

Entity.ID holds one public record per entity. The Verify API is the same record, read by your software.

01

Onboarding

Replace the certificate-of-incorporation upload with a lookup. Approve in seconds, not days.

02

Payments and payouts

Check standing before money moves, and again before it moves the next time.

03

Agent counterparties

An agent calling your API carries an entity. Check its owner and mandate before you serve it.

04

Marketplaces

Show a verified badge next to sellers that are real entities with verified members.

05

Monitoring

Subscribe to a record and get told when standing, members or rules change.

06

Attestations

Ask the entity to sign a statement. The signature is checkable against its record.

A record you can call beats a certificate you can scan.
