How this service works
Extract deterministic Markdown and metadata from a public HTTPS PDF URL or a base64 PDF payload. Enforces public-network fetching, an 8 MiB limit, and a caller-selected page cap.
Output
Returns deterministic Markdown text representing the PDF content, along with document metadata such as page count, title, and author fields. The output is structured to be LLM-friendly and consistently formatted across calls for the same input.
Example use cases
Research paper ingestion for LLM pipeline
“Grab this academic PDF at https://arxiv.org/pdf/2401.00001.pdf and convert it to Markdown so I can feed it into my summarization pipeline — limit it to the first 20 pages.”
Contract text extraction for review
“I have a contract PDF encoded in base64 — can you convert it to Markdown so I can read and analyze the clauses? Cap it at 50 pages.”
Invoice data extraction from PDF URL
“Pull the PDF invoice from https://invoices.example.com/inv-12345.pdf and extract its contents as Markdown so I can parse the line items.”
Technical details
Endpoint
POSThttps://api.utilia.ink/base/v1/pdf/to-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, reproducible Markdown extraction from a PDF — particularly useful in agentic pipelines where consistent output across repeated calls matters. Ideal for LLM pre-processing, document QA, and structured extraction from publicly accessible PDFs or base64-encoded payloads. Prefer this over general-purpose scraping tools when the input is specifically a PDF and clean Markdown output is required.
Side effects
- Non-public or private HTTPS URL returns a network/fetch error
- PDF exceeds the 8 MiB size limit, returning a payload-too-large error
- Requested page cap exceeds actual document length, truncating output gracefully
- Malformed or corrupt base64 payload returns a parse error
- Non-PDF file at the URL returns an unsupported format error
- PDF with only scanned images (no embedded text) returns empty or near-empty Markdown
