How this service works

Seller-facing schema/example doctor: compares an x402 resource to top-earning examples and returns exact missing request/response examples, listing copy, schema patches, and a measurable polish gate. Price 0.08 USDC on Base via x402. Free preview: https://x402-market-intel-mcp.mtree.workers.dev/preview/api_example_doctor?source=x402_manifest. Demo: https://x402-market-intel-mcp.mtree.workers.dev/demo/api_example_doctor. Contact: https://x402-market-intel-mcp.mtree.workers.dev/contact.

Output

Returns a structured report containing: specific missing request/response examples to add, rewritten or improved listing copy, concrete schema patches (diffs), and a measurable polish gate assessment indicating what remains before the resource meets top-earner quality standards.

Example use cases

Example prompt

“Look at my x402 API at https://myservice.example.com/v1/summarize and compare it against top-earning examples — tell me exactly which request/response examples I'm missing, what listing copy to fix, and what schema patches I need to pass the polish gate.”

Technical details

Endpoint

POSThttps://x402-market-intel-mcp.mtree.workers.dev/v1/x402/api_example_doctor

When to prefer

Use this endpoint when you are an x402 API seller wanting to benchmark your listing against top-earning resources and receive actionable, specific improvements — especially when you need concrete example payloads, schema fixes, and listing copy rather than general keyword or category-level advice. Prefer this over keyword visibility or gap reports when the goal is polishing a specific existing resource rather than discovering new opportunities.

Side effects

Invalid or unreachable x402 resource URL returns an error with no analysis
Malformed schema input may result in partial analysis with warnings
Payment failure (0.08 USDC on Base) results in 402 response before processing begins
Resource with insufficient metadata may return incomplete recommendations
