How this service works
Choose Blockchain Money Map for human-readable public blockchain reports or x402-paid agent API services.
Output
Returns a JSON object containing lint results for the provided schema and response samples, including identified compliance issues, validation errors, warnings, and recommendations specific to the selected lint profile (api, mcp, x402, or auto-detected).
Example use cases
Validating a new x402 endpoint schema
“I just built a new x402-paid endpoint and I want to make sure the response contract is compliant — can you lint it using the x402 profile? The endpoint path is /api/v1/data-feed and it expects 0.05 USDC on base-mainnet.”
Checking MCP tool x402 integration
“I have an MCP tool called 'fetch-blockchain-report' and I want to verify its x402 payment contract is correctly structured — can you lint it with the mcp profile and check for any spec violations?”
Auto-detecting schema compliance issues
“I'm not sure what lint profile to use — can you auto-detect the right one and lint this API schema sample and response sample I have? I need to know if there are any x402 contract issues before I deploy.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-response-contract-linterWhen to prefer
Choose this endpoint when you need to validate x402 payment protocol response contracts, API schemas, or MCP tool definitions for spec compliance before deployment. Especially useful for developers building x402-paid agent APIs who need to catch schema and contract errors early. Prefer this over generic JSON schema validators when x402-specific compliance rules and MCP tool context matter.
Side effects
- Invalid or missing schema_sample causes linting failure
- Unsupported lint_profile value returns validation error
- Malformed tool_context fields (e.g. oversized strings) rejected with 400
- Empty or null response_sample may produce incomplete lint results
- Network or currency values not recognized by the linter may be flagged
