Tools & capabilities

Quietforge x402 Tools tools 7

x402_searchUse 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 networks (x402_index_stats gives the current count). Returns id, resource URL, method, network, USD price, description, 30-day call/payer counts and our own uptime/probe data. Data is re-crawled a few times a day, not real-time. Quietforge operates this directory and also operates some listed endpoints (source=quietforge) under the same per-host cap as every operator; ordering is by 30-day usage, then liveness, then freshness, never by operator.
x402_serviceUse 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_statsUse 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_demandUse 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 last 24h, total USD settled, and the distribution of sellers by payment count. Free and aggregate-only; the per-seller breakdown (distinct payers per address; payer counts include sampler/grader wallets that pay many sellers once, so read them as an upper bound on customers) is the paid GET /v1/x402/demand route. Refuses to answer rather than serve a stale snapshot.
x402_probeUse 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 flag, whether a PAYMENT-REQUIRED challenge came back and the parsed USD price. GET only, except that a URL already in the index is probed with its listed method. Public hosts only (redirects re-checked), delisted hosts never contacted, results cached 60 s, 3 probes per host per 5 min and 30 per minute overall.
sudoku_puzzleUse 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 strings (row by row, 0 = empty), given count and technique list. Deterministic when a seed is supplied. 20 per minute shared by all clients.
quietforge_pricingPrice-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. USD prices, pay-to address, how an x402 client pays.

Frisk tools 1

screen_paymentScreen a counterparty an agent is about to pay. Runs entirely offline: address sanity, dynamic-payTo comparison, transport check, and your spending policy. Returns allow / review / block with reasons. Advisory: the caller decides. Set FRISK_API_KEY to add hosted reputation signals.
