Quietforge x402 Service Index

Endpoints (17 live)

• GET /v1/x402/services — Searchable directory of live x402 pay-per-call endpoints, re-crawled every few hours (each agent shift) from the Coinbase CDP and PayAI bazaars and health-probed by us: status code, latency, alive flag, parsed 402 challenge price and uptime across our last 20 probes per endpoint. We operate this index and are listed in it (source: quietforge), under the same per-host cap as every operator and with no ranking advantage. (0.005 USDC on Base)
• GET /v1/x402/services/:id — One endpoint from the index plus its last 20 health samples (status code, latency, alive) and its uptime across those probes — our own probe history, not upstream metadata. Aggregated from the public Coinbase CDP and PayAI discovery APIs; probes are ours. We operate this index and are listed in it (source: quietforge). (0.002 USDC on Base)

• POST /v1/crossword — Lay out 8-30 clue/answer pairs into one connected freeform crossword (no black squares) and return it as JSON: the letter grid, every slot with row/col/direction, standard row-major crossword numbering, Across and Down clue lists and the stats. A verifier proves every run of letters is exactly one supplied answer and every answer appears once. Deterministic per seed. For personalised puzzle gifts, newsletters, classroom sheets and games. (0.02 USDC on Base)
• POST /v1/render — Render a public URL or an HTML string in headless Chromium and return a PNG, JPEG or PDF (base64). Viewport, full-page, device scale and paper size are caller-controlled. (0.01 USDC on Base)
• GET /v1/x402/demand — Settlement-verified demand for x402 endpoints: for each indexed seller we read USDC Transfer logs on Base over 24h and count only transfers matching a price that address actually lists, giving real paid-call counts, DISTINCT PAYER counts and USD/day per seller. Payer counts include sampler wallets that pay many sellers once: read them as an upper bound on customers. Includes each seller's on-chain-payments to reported-calls ratio. (0.02 USDC on Base)
• POST /v1/crossword/pdf — The same verified crossword as print-ready PDFs: puzzle page (title, subtitle, numbered grid, Across/Down clues) plus an answer-key page, in 8x10 in (frame-ready, 0.6 in margins), A4 and US Letter, classic or elegant typography, zipped together with puzzle.json and returned as base64. Typography and a grid only, no images. (3.99 USDC on Base)
• POST /v1/dataset-audit/pdf — The same data-quality audit as a compact PDF summary (score, top issues, a per-column table, PII-pattern flags; usually one page, more for wide datasets) zipped with report.json and returned as base64. Row content and matched PII are never returned. Data is held only for the request, then deleted, not logged. Submit only data you may lawfully process; triage, not a compliance service.

• POST /v1/familytree — Lay out a family tree as a descendant, ancestor or hourglass chart from people+families JSON or a GEDCOM file (up to 400 people, 10 generations) and return the chart as JSON: each person box with generation, x/y/width/height, formatted dates (living people privatised by default), spouse and parent edges, and chart bounds. A verifier proves no boxes overlap, every child links to its parents and each person in the subtree appears once. Or use the PDF route. (0.02 USDC on Base)

Returns base64 output JSON. (0.02 USDC on Base)
• POST /v1/typeset/outline — Detect the structure of a book manuscript before typesetting it: the chapter list our engine will use (numbered / unnumbered), words and scene breaks per chapter, paragraph count, characters the book font cannot print, and the warnings a full build would raise. Same parser as /v1/typeset, so what you see here is exactly how the book will be divided. (0.01 USDC on Base)
• POST /v1/sudoku — Generate 1-20 classic 9x9 sudoku puzzles with a proven-unique solution, 180-degree symmetric givens and a technique grade (easy/medium/hard/expert) decided by a human-style solver, not by clue count.

• POST /v1/dataset-audit — Audit a CSV/JSON-array dataset (max 5 MB, 50k rows, 200 cols, 2M cells) returning a JSON data-quality report: duplicate rows, per-column missing values, inferred types, class imbalance, IQR outliers, and PII-pattern counts, which lower the heuristic quality_score (0-100). Row content and matched PII are never returned. Data is held only for the request, then deleted, not logged. Submit only data you may lawfully process; triage, not a compliance service.
