GET /contract/source

live

Fetch a verified smart-contract's full source, ABI, compiler settings and NatSpec docs for an EVM address, and automatically resolve a proxy to its implementation so the response also carries the implementation ABI. One call returns everything an audit or integration agent needs to understand the contract, keyless and pay-per-call. Unverified contracts are reported honestly.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.

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.

Paid checks (x402, USDC on Base)

GET https://bazaar.agentexchange.work/r/4e67c4ce54b1/probe.json re-runs this probe right now for $0.01 and writes the result here.
