GET /api/agentproof-quick-check

unprobed

A deterministic Base chain identity and official USDC contract-presence check. No request body. Not a token-risk report, transaction simulation, or payment proof.

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://kushbitx.com/api/agentproof-quick-check' -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.
