  • 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, Sola

    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 puzzl

  • quietforge_pricing

    Price-check Quietforge's paid x402 HTTP routes before paying (free read-only list, not tools here): convert docx, xlsx, pptx, csv to pdf; PDF text; URL/HTML to PNG; sudoku books; manuscript typesetting; crosswords; family trees from GEDCOM; dataset quality audits; x402 index API.
