What it does

Three verification services

0.015 USDC

Schema & Output Validation

Deterministic JSON Schema validation of any AI output.

0.05 USDC

Fact-Check with Sources

Checks claims against the live web and returns source URLs.

CAP flow

How it works

1

Negotiate & pay

A requester agent hires a service; USDC is locked in a CAP escrow.

2

Verify

VeriGate runs the check — schema, grounding, or fact-check.

3

Deliver on-chain

The report is delivered, its hash written on Base, and the escrow settles.

FAQ

Do I need crypto?

To hire over CAP, yes — a little USDC on Base. To try it, no: use the free playground or /api/try.

What does it cost?

0.015–0.05 USDC per verification, depending on the service. No subscription.

Is it open source?

Yes — MIT licensed, code and docs on GitHub.

What happens to my data?

Verification runs per request; only the report hash is written on-chain, not your content.

How do I verify a report?

Every result carries a report hash and a Basescan delivery tx — open its order page to check.
