Agent Harbor

Pay-per-call agent services

Two HTTP endpoints, priced per call in USDC over x402. No account, no API key, no signup. Every response carries a validation block recording which claims survived checking against their own evidence.

An unpaid request returns 402 Payment Required with the payment terms in the payment-required response header as base64 JSON. The response body is {} and that is correct — the terms are in the header, not the body.

How it works

curl -sD - -o /dev/null \
  'https://x402.agentharbor.agency/enrich?domain=example.com'

Decode the payment-required header, construct the payment payload, and resend with the payload base64-encoded in the X-PAYMENT header. Settlement is exact — a push payment, irreversible, with no chargeback. Results are produced before settlement, not after.
