GET /lookup-paid/:agent_id

unprobed

Same lookup as /lookup/{agentId} — this route exists to measure willingness-to-pay and x402 Bazaar discoverability, not because the result is different or better paid.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X GET 'https://vadium-lookup.onrender.com/lookup-paid/:agent_id' -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.
