Free preview includes paid_request_body + preview_id; paid route is now $0.03 to match try-it conversion pricing. Price 0.03 USDC on Base via x402. Demo: https://x402-market-intel-mcp.mtree.workers.dev/demo/endpoint_risk. Contact: https://x402-market-intel-mcp.mtree.workers.dev/contact.

Example use cases
Example prompt

Technical details
Endpoint
POSThttps://x402-market-intel-mcp.mtree.workers.dev/v1/x402/endpoint_riskWhen to prefer
Use this endpoint when an AI agent is about to pay for an unknown or untrusted x402 API call and needs a pre-payment safety check. Prefer it over general API validation tools when the specific concern is x402 payment terms, replay risk, seller binding, and cap/block decisions for micropayment routes.
Side effects
- Invalid or unreachable endpoint URL returns an error verdict
- Malformed x402 headers on target endpoint may produce incomplete term checks
- Payment of $0.03 USDC on Base required for full report; missing payment returns free preview only
- Network timeout on target endpoint inspection returns partial results
