How this service works
One-call x402 service selector for buyer agents: given an intent and budget, return the pay/skip/reroute verdict first, then warnings, price/payment metadata, evidence, and fallback action before the agent spends. Price 0.03 USDC on Base via x402. Demo: https://x402-market-intel-mcp.mtree.workers.dev/demo/service_rank. Contact: https://x402-market-intel-mcp.mtree.workers.dev/contact.
Output
Returns a structured verdict (pay/skip/reroute) as the first field, followed by any warnings, exact price and payment metadata for the top-ranked x402 service, supporting evidence for the recommendation, and a fallback action if the top choice is unsuitable.
Example use cases
Example prompt
“Before I spend anything, rank the available x402 services for my intent 'get real-time weather data for a city' with a budget of 0.05 USDC and tell me whether I should pay, skip, or reroute — and flag any warnings about pricing or service quality.”
Technical details
Endpoint
POSThttps://x402-market-intel-mcp.mtree.workers.dev/v1/x402/service_rankWhen to prefer
Use this endpoint when a buyer agent needs to select among multiple x402 pay-per-call APIs before committing funds — especially when budget constraints matter, when rerouting to a cheaper/better alternative is desirable, or when the agent needs a pre-payment risk/value verdict rather than just a list of options. Prefer over raw API directories when a decision verdict and warnings are needed, not just discovery.
Side effects
- Intent too vague to match any x402 service — returns low-confidence verdict with reroute suggestion
- Budget below minimum price of any matching service — returns skip verdict with budget warning
- No x402 services found in the requested category — returns empty evidence set and fallback action
- Payment processing failure for the $0.03 USDC oracle fee — returns 402 with payment instructions
- Malformed request body missing required intent or budget fields — returns 400 validation error
