How this service works
Pay-per-call document conversion, PDF text extraction, headless-browser rendering of a URL or HTML to PNG / JPEG / PDF, a health-probed directory of x402 pay-per-call endpoints, a sudoku generator (solver-verified, technique-graded puzzles as JSON or a print-ready A4/Letter book), a book typesetter (prose manuscript to a KDP-ready interior PDF + editable docx), a crossword generator (verified freeform grid from your clue/answer pairs as JSON or print-ready PDFs), a family tree chart layout engine (descendant / ancestor / hourglass charts from people+families JSON or a GEDCOM file, as verified layout JSON or print-ready poster and tiled PDFs), and a dataset quality audit tool (duplicates, missing values, type consistency, class imbalance, numeric outliers and PII-pattern counts for a CSV/JSON dataset, as JSON or a one-page PDF summary). Payment: x402 (USDC on Base). No signup, no API key.
Output
Returns a paginated JSON object with a count of matched services, total available, and an array of service records each containing: endpoint URL, HTTP method, price in USD and atomic units, payment asset and address, network (CAIP-2), source(s), uptime probe results (alive status, latency, last probed timestamp), 30-day call and payer counts, service name, description, and tags. Also includes attribution note and generation timestamp.
Example use cases
Finding affordable AI search endpoints
“Can you search the x402 services directory for any neural search or web search APIs priced at $0.01 or less that are currently alive and responding?”
Exploring Coinbase-curated API listings
“List all x402 endpoints that come from the CDP source — I want to see what Coinbase has curated, up to 100 results.”
Discovering document processing pay-per-call APIs
“Search the Quietforge x402 directory for any document conversion or PDF-related endpoints — I want to see what's available without needing to sign up anywhere.”
Technical details
Endpoint
GEThttps://qf-api.quietforge-studio.workers.dev/v1/x402/services?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover x402 pay-per-call APIs without signup or API keys, especially when filtering by price ceiling, network, uptime status, or discovery source. Prefer this over generic API directories when the agent needs micropayment-compatible endpoints on Base or other blockchains, or when you want health-probed liveness data alongside listings.
Side effects
- Invalid filter combination returns empty results array
- Malformed network CAIP-2 string returns no matches
- offset beyond total count returns empty services array
- Unknown source enum value may be rejected or return error
- Service may return stale probe data if probing is delayed
