## Tools (as reported by the server, not verified)

- `x402\_market\_stats`: Get measured statistics about the x402 ecosystem economy: total 30-day revenue across sampled resources, revenue concentration, revenue at a given rank, price distribution and payer concentration. Free. Use this to decide whether building or buying on x402 is worth it.
- `x402\_check\_endpoint`: Check whether an x402 endpoint is alive and emits a valid HTTP 402 payment challenge, before you pay it. Free liveness check. Returns reachability, status code and whether a valid challenge was found.
- `x402\_gas\_price`: Current gas price and estimated simple-transfer cost for an EVM chain. Free preview route. Supports base, polygon, arbitrum, optimism, ethereum.
- `x402\_facilitator\_guide`: Which x402 facilitators actually settle payments, measured by probing each with a real signed EIP-3009 payload. Tells you which are keyless, which need API keys, which are testnet-only and which are unreachable. Free. Use before choosing a facilitator.
- `x402\_verified\_merchants`: List x402 merchants that have been VERIFIED to accept payment — each one actually paid with real USDC on Base, with the settlement transaction hash. This is different from a liveness probe: public censuses only check whether a 402 is emitted, not whether paying works. Use this to find endpoints that
- `x402\_audit\_merchant`: Full paid due-diligence audit of an x402 merchant: live probe, price-drift detection between advertised and actual challenge price, settlement history, unique buyer count, and on-chain verification that USDC actually reaches the payTo address. Returns PASS/CAUTION/AVOID with evidence. Costs $0.01 US
