How this service works

Fetch a PDF from a URL, extract its text, and return a concise AI-generated summary - factual, no information added beyond what's in the document. Body: {"url":"https://…/file.pdf","maxWords":200?}. Uses the same OpenAI-compatible gateway as /v1/chat/completions internally; the model that actually served is disclosed in the response.

Output

A JSON object containing the source URL, the AI model used (openai/gpt-4o-mini), the number of pages in the PDF, a prose summary string, the total word count of the original document, a flag indicating whether the input was truncated, and the word count of the generated summary.

Example use cases

Research paper digest for literature review

“Summarize this academic paper for me in 300 words so I can decide if it's worth reading in full: https://arxiv.org/pdf/2303.08774.pdf”

Legal document quick overview

“Give me a 100-word summary of this PDF contract so I can get the gist before the meeting: https://example.com/contract-draft.pdf”

Whitepaper briefing for investor

“I need a 200-word summary of this blockchain whitepaper at https://example.com/project-whitepaper.pdf — just the key points about what they're building and the tokenomics.”

Technical details

Endpoint

POSThttps://agent402.tools/api/pdf-summarize

When to prefer

Use this endpoint when you need a fast, pay-per-call AI summary of any publicly accessible PDF without managing API keys, model credentials, or document parsing infrastructure. It is ideal for agents that encounter PDF URLs at runtime and need to extract meaning on the fly. Prefer it over general-purpose LLM calls when you want document fetching, text extraction, and summarization bundled into a single atomic operation paid for in USDC per call.

Side effects

PDF URL is not publicly accessible or returns 4xx/5xx — endpoint cannot fetch the document
URL points to a non-PDF file — parsing will fail or produce garbage output
PDF is encrypted or password-protected — text extraction will fail
maxWords outside the 50-500 range may produce unexpected summary length
Very large PDFs may be truncated (truncatedInput: true), resulting in an incomplete summary
Network timeout if the remote PDF server is slow to respond
