How this service works

PDF to Markdown: Convert a PDF document to clean, LLM-ready Markdown. Provide a direct URL to the PDF or base64-encoded file bytes. Auto-extracts headings, paragraphs, lists and tables. Ideal for feeding reports, papers and contracts into RAG pipelines. Pay per call in USDC on Base via x402 — POST https://x402.freeq.one/tools/pdf_to_markdown.

Output

Returns a JSON object with a 'result' field containing the extracted Markdown text of the PDF, including headings, paragraphs, bullet lists, and tables, optionally truncated to the specified max_length.

Example use cases

Research paper ingestion for RAG

“Take this PDF of a research paper at https://arxiv.org/pdf/2401.00001.pdf and convert it to markdown so I can chunk and embed it into my vector store. Limit the output to 80000 characters.”

Contract text extraction for AI review

“I have a legal contract PDF at https://example.com/contracts/agreement.pdf — convert it to markdown so my AI can analyze the clauses. Keep the full text, no truncation.”

Financial report parsing for LLM summarization

“Convert this annual report PDF to markdown — the file is base64-encoded and I'll pass the bytes directly — so I can feed it into a summarization pipeline. Cap it at 100000 characters.”

When to prefer

Choose this endpoint when you need to convert a PDF (by URL or raw bytes) into clean, structured Markdown suitable for LLM ingestion, RAG pipelines, or document analysis — especially when you need auto-extracted headings, lists, and tables rather than raw text dumps. Prefer it over generic web scrapers when the source is definitely a PDF file.

Side effects

Invalid or unreachable PDF URL returns an error response
Base64 payload exceeding 28MB limit is rejected
Corrupted or password-protected PDFs may fail to parse
max_length too small may truncate essential content
Payment failure or insufficient USDC balance blocks the call
