minia2a x402-contract-scan

Use this endpoint when you need to programmatically audit an x402 contract or payment endpoint for security before integrating or transacting with it. Particularly valuable when you want to verify that a contract enforces payment correctly, rejects forged transaction hashes, and is not vulnerable to replay attacks. Prefer this over manual review when you need fast, automated assessment as part of an agentic workflow.

• Invalid or missing input parameters — endpoint returns an error indicating required fields
• Unreachable contract address or endpoint — scan cannot be completed, returns connectivity error
• Malformed query parameters — returns validation error
• Rate limiting or payment failure — 402 response if payment is not properly attached
• Scan timeout for complex contracts — may return partial results or timeout error
