Tools as reported by the server

• x402_search
  Use this to find a pay-per-call x402 API for a given task, network or price cap before calling it (mostly USDC on Base; check each row's network and asset, some are testnet or other assets). Searches a health-probed directory of live x402 pay-per-call HTTP endpoints on Base, Solana and other network
• x402_service
  Use this to check whether one endpoint from x402_search is reliable enough to pay: its record plus its last 20 health probes (status code, latency, alive) and uptime across them.
• x402_index_stats
  Use this to see how much this index covers (it is a subset of the x402 market, not all of it) and to sanity-check x402_search coverage before relying on it. Summary of the index: totals, how many endpoints answered on the last probe, counts per network and per source, and when the crawl ran.
• x402_demand
  Use this to answer "is anyone actually paying for x402 APIs today" with settled on-chain numbers instead of listings. Market-level demand signal for the x402 ecosystem, verified against on-chain USDC settlement on Base rather than self-reported call counts: how many seller addresses were paid in the
• x402_probe
  Use this to check a URL you are about to pay (or one you operate) for a well-formed x402 challenge before sending funds; a challenge is no guarantee the service delivers. Makes ONE live unpaid request to a public http(s) URL and reports whether it is an x402 endpoint: status code, latency, alive fla
• sudoku_puzzle
  Use this when a user wants a sudoku to play or print, or an app needs a verified puzzle at a named difficulty. Generates ONE sudoku puzzle with a unique solution, 180-degree symmetry, graded by the solving techniques it needs (easy | medium | hard | expert). Returns 81-char puzzle and solution strin
