ERC-8004 Inspector agent lookup (identity + reputation) — per call

Verdict: not verified by an unpaid GET. 405/400: the 402 sits behind the declared method. This says nothing about whether the route works when called as declared.

Try it (unpaid: shows the 402)

curl -si -X POST 'https://contextiq.trango-compute.com/api/v1/erc8004-inspector/x402-v2' -H 'accept: application/json' -H 'content-type: application/json' --data '{}'

The catalog declares POST. 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.

Paid checks (x402, USDC on Base)

GET https://bazaar.agentexchange.work/r/998c919a6e16/probe.json re-runs this probe right now for $0.01 and writes the result here. POST https://bazaar.agentexchange.work/featured with {"id":"998c919a6e16"} places this resource at the top of the report and search pages for 30 days for $1.00, labelled. Unpaid requests answer 402 with the terms. Pricing.
