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
A JSON object containing an array of pages (each with a page number and extracted text string), a metadata object (including document title), and a total page_count integer.
Example use cases
Research paper text mining
“I have a PDF of a scientific paper at https://arxiv.org/pdf/2401.00001.pdf — can you pull out all the text from it, page by page, so I can search through the content?”
Contract clause review
“Here's a base64-encoded copy of a legal contract I need to read through. Can you extract all the text from it so I can check what clauses are in there?”
Invoice data extraction pipeline
“I'm getting invoice PDFs from vendors and need to pull the raw text out of each one so I can parse the line items. Can you extract the text from this PDF at https://vendor.example.com/invoice-2024-05.pdf?”
Technical details
Endpoint
POSThttps://qf-api.quietforge-studio.workers.dev/v1/pdf/text?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need per-page structured text extraction from a PDF without any signup, API key, or subscription — ideal for pay-as-you-go agent workflows. Prefer it when you have either a public URL or raw PDF bytes (up to 15 MB) and need clean JSON output with page-level granularity and document metadata. Best for lightweight extraction tasks billed at $0.005 per call via USDC on Base.
Side effects
- PDF URL is not publicly accessible or returns a non-200 status — endpoint cannot fetch the document
- PDF exceeds 15 MB when base64-encoded — request rejected
- PDF is image-only or scanned without embedded text — returns empty or near-empty text per page
- Malformed base64 input — parsing error returned
- Payment via x402/USDC fails or is insufficient — 402 response, no extraction performed
- Password-protected or encrypted PDF — extraction fails or returns empty text
