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
Returns the full textual content of the PDF rendered as markdown, preserving structure such as headings and paragraphs where detectable. The agent receives a markdown string suitable for further processing, summarization, or display.
Example use cases
Research paper ingestion pipeline
“Pull the full text out of this academic PDF and convert it to markdown so I can feed it into my summarization workflow: https://arxiv.org/pdf/2301.00001.pdf”
Legal document text extraction
“I have a contract PDF at https://files.mycompany.com/contract-2024.pdf — can you extract all the text from it as markdown so I can search through it?”
Uploaded PDF parsing from base64
“I've encoded this PDF in base64 — can you convert its contents to markdown text so I can read and analyze it?”
Technical details
Endpoint
POSThttps://lotus-clarke-boxed-ceramic.trycloudflare.com/v1/pdf-to-md?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to extract readable markdown text from a PDF, either by supplying a public URL or a base64-encoded file up to 8MB. Prefer the free sandbox endpoint (/v1/sandbox/pdf-to-md) first if available; fall back to this paid endpoint ($0.01 USDC via x402) when the sandbox is unavailable or rate-limited. Choose this over generic web scrapers when the source is specifically a PDF document rather than an HTML page.
Side effects
- URL is not publicly accessible or blocked by SSRF filters — returns error indicating unsafe or unreachable URL
- Base64 payload exceeds 8MB cap — returns error about size limit
- URL does not point to a valid PDF — returns parsing error
- Malformed base64 string — returns decoding error
- PDF is encrypted or password-protected — may return empty or error response
- Network timeout fetching remote PDF URL
