  x-guidance: 'Quietforge Docs API: pay-per-call HTTP tools for agents, paid in USDC on Base (eip155:8453) over x402 v2; no signup, no API key. Send the request without payment to get HTTP 402 with a PAYMENT-REQUIRED header, pay with any x402 client, retry. Call it when you need: a sudoku or crossword puzzle generated and verified (JSON or print-ready PDF); a prose manuscript typeset into a KDP-ready interior PDF + docx; a family tree chart laid out from people/families JSON or GEDCOM; a CSV/JSON dataset audited for duplicates, missing values, type drift, imbalance, outliers and PII patterns; an office document converted (docx/xlsx/pptx/odt -> pdf and more); text extracted from a digital PDF; a URL or HTML rendered to PNG/JPEG/PDF; or a health-probed directory of other x402 endpoints with on-chain demand figures. Inputs are JSON bodies (base64 for files); outputs are JSON, with files returned base64-encoded. Prices are fixed per call and listed in each operation''s x-payment-info. Free routes: GET /health, GET /.well-known/x402, POST /v1/dataset-audit/preview. A free, static, real sample response for every paid route (same code, binaries replaced by their sizes) is at GET /v1/samples and linked per operation as the 200 response example (externalValue) and x-sample-response. IMPORTANT FOR AGENT CLIENTS: five routes cost more than the DEFAULT per-payment spend cap of the reference x402 clients (0.10 USDC in x402-fetch and x402-axios, $1.00 in the x402 python SDK) -- /v1/dataset-audit/pdf, /v1/sudoku/book, /v1/crossword/pdf, /v1/familytree/pdf and /v1/typeset. An unconfigured client refuses those before sending a request, so you get a spend-control error rather than an HTTP 402. Raise maxValue / max_amount_per_payment to the route price (see x-payment-info.client_spend_cap per operation for the exact call). Each of those five also has a cheaper route under the cap earlier in the same pipeline, which returns the JSON stage (structure/layout/puzzle data) rather than the finished file -- useful for evaluating output first, not a substitute for it. Every other route is under both default caps.'

          why: These caps are client-side library defaults, so an unconfigured client refuses this route before it ever contacts us. You will see a spend-control error, not an HTTP 402.

            returns: the JSON stage of this pipeline (structure/layout/puzzle data), NOT the finished file this route produces -- useful to evaluate output before raising your cap, not a substitute for it.
