How this service works
Free website triage plus x402 audits, Base USDC receipt verification, robots-aware URL preflight, agent-readable extraction, metadata, and copy-ready AI-discovery fixes.
Output
Returns a JSON object with a numeric compliance score (0–100), a budget check showing whether the supplied USD amount is within budget, an array of named checks each with pass/fail status and evidence, the inspected resource's URL and service name, payment options listing asset address, payTo address, scheme, network, price in USD, atomic amount, and max timeout, a recommendation string ('proceed' or similar), known limitations of static inspection, the x402 version detected, and a timestamp of when the inspection occurred.
Example use cases
Preflight check before paying an agent API
“Before I spend any USDC, can you inspect https://api.someagent.ai/data using x402 audit and tell me the compliance score, what asset it accepts, how much it costs, and whether you recommend proceeding?”
Validating a third-party x402 endpoint
“I found an x402-gated endpoint at https://data.thirdparty.io/report — can you audit it to check the payment address, make sure it's using a known asset on Base, and flag any compliance issues before I integrate it?”
Debugging x402 configuration for own API
“My API at https://myservice.dev/api/insights is supposed to accept x402 payments but agents keep failing to pay — can you run an x402 inspect on it and tell me what's wrong with the payment configuration?”
Technical details
Endpoint
POSThttps://agentready-audit.seshiccse023.chatgpt.site/api/x402/inspectWhen to prefer
Use this endpoint when an AI agent or developer needs to pre-validate an x402-gated URL before attempting payment, specifically to check Base USDC payment options, verify the payment address and asset are known and well-formed, get a structured compliance score, and receive an explicit proceed/warn recommendation. Prefer this over manual inspection when automating agent payment workflows on the Base network.
Side effects
- Target URL is unreachable or returns non-x402 response — audit may return failed checks or empty payment options
- Invalid or malformed URL input — returns error response
- Target URL uses an unsupported x402 version — version check fails
- Static inspection cannot guarantee live settlement will succeed — flagged in limitations array
- Rate limiting or network timeouts when fetching target URL — may result in incomplete checks
