How this service works
Call when an agent needs text extracted from a public PDF URL (SSRF-safe) or pdf_base64 (8MB cap) as markdown. Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/pdf-to-md first.
Output
A Markdown-formatted string containing the extracted text and structure from the PDF, preserving headings, paragraphs, and lists where detectable.
Example use cases
Research paper content extraction
“I need the full text of this academic paper as markdown so I can summarize it — here's the PDF URL: https://arxiv.org/pdf/2301.00001.pdf”
Invoice data extraction for automation
“Pull all the text out of this invoice PDF and return it as markdown: https://mycompany.com/invoices/inv-2024-001.pdf”
Offline PDF file ingestion
“I have a base64-encoded PDF of a product manual — can you convert it to markdown so I can search through it?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/pdf-to-md?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract readable text from a PDF document — either from a public URL or as a base64-encoded file — and want the output in Markdown format. Prefer the free sandbox endpoint (POST /v1/sandbox/pdf-to-md) for testing. Choose this paid endpoint for production use or when the sandbox is unavailable.
Side effects
- URL is not publicly accessible or returns a non-PDF content type
- PDF exceeds the 8MB base64 cap (~11MB encoded)
- URL triggers SSRF protection (private IP ranges, localhost, internal hostnames)
- Malformed or encrypted PDF that cannot be parsed
- Payment of exactly $0.01 USDC not included or rejected
