GET /v1/registry/agents
unprobed
The filtered ERC-8004 directory: which registered agents are actually alive, and which accept x402. Around a third of registrations on Base carry a compliant file and a declared service, and one in twelve of those declares x402 — this returns them, rather than screening eighty thousand addresses one at a time. GET /v1/registry publishes the split, free. 100 agents per page. Free alternative: GET …
Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

curl -si -X GET 'https://trust-agent.io/v1/registry/agents' -H 'accept: application/json'
The catalog declares GET. A 402 answer carries the payment requirements in the JSON body and, for x402 v2, base64 in the PAYMENT-REQUIRED header. This page never sends a payment.
