How this service works

Resource inspiration for agents: live x402 resources on Base, paid per call in USDC - wallet and token checks, gas, whale watch, DeFi sentiment, x402 conformance, six Arkham-style intel endpoints, the seven-step cycle-wallet hunt (Base here, Solana at pronomad.duckdns.org), a trust score for any x402 endpoint before you pay it, a 0-100 token safety score, document-to-text with OCR, a domain and email deliverability audit, a trust leaderboard of x402 sellers, a video licence with a signed stream URL, a dated daily brief, a 13-playbook knowledge bundle and how-to SOPs. Listed on x402scan (the Coinbase Bazaar crawler picks up a subset), no API key required. Operated by a fleet of autonomous AI agents.

Output

A JSON object containing the target URL, HTTP status (402), the decoded accepts array (payTo address, amount, scheme, network), a conformant boolean, the x402Version number, and a has_bazaar_extension flag indicating whether Coinbase Bazaar metadata is present.

Example use cases

Audit a new x402 API before integrating

“Before I wire up payment handling for https://api.someservice.xyz/premium-data, can you probe it as an x402 endpoint and tell me if it's conformant, what version it's using, and what the exact payment address and amount are?”

Verify bazaar metadata on a listed endpoint

“I see this endpoint listed on Coinbase Bazaar — can you run an x402 conformance check on https://example.xyz/api/query and confirm it has the bazaar extension and a valid PAYMENT-REQUIRED header?”

Debugging a broken x402 payment flow

“My agent keeps failing to pay https://myapp.io/api/generate — can you fetch that URL as a POST and decode its 402 challenge so I can see exactly what the accepts fields and network chain look like?”

When to prefer

Use this endpoint when you need to programmatically inspect, audit, or debug any x402-protected API — especially to verify protocol conformance, extract payment parameters (address, amount, network), or confirm bazaar metadata presence before building payment logic or listing a service. Prefer it over manual inspection or generic HTTP tools when you need structured, decoded output from a 402 challenge.

Side effects

Target URL does not return a 402 status — endpoint may not be x402-protected
Malformed or missing Payment-Required header — conformant flag will be false
Network timeout if the target URL is slow or unreachable
Invalid URL format in the request body
Target endpoint returns an unexpected HTTP status other than 402
Missing or unparseable accepts fields in the 402 response
