How this service works
Pay-per-call APIs for AI agents via x402 on Base: web fetch, HTTP proxy, page extract, and crypto market data.
Output
Returns clean text extracted per page from the PDF, along with document-level metadata such as title and author. Output is structured by page, covering up to 50 pages and 100K characters. Files that are non-PDF, encrypted, or image-only (requiring OCR) are returned unbilled with an appropriate indication.
Example use cases
Research paper text extraction
“I need the full text from this academic paper PDF at https://arxiv.org/pdf/2301.00001 — extract all the pages and tell me the title and authors listed in the document.”
Legal document reading
“Pull the text out of this public contract PDF at https://filings.sec.gov/contract.pdf so I can read through it — get up to 20 pages and include any metadata like title or author.”
Report summarization pipeline
“Fetch the text from this government report PDF at https://cdc.gov/annual-report-2023.pdf — I want all available pages extracted so I can summarize the key findings.”
Technical details
Endpoint
GEThttps://horizonpulse.dev/api/pdf?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a public HTTP/HTTPS URL pointing to a real PDF with an embedded text layer (not a scanned image PDF) and need clean per-page text plus title/author metadata. It is ideal for processing research papers, reports, filings, and other text-layer PDFs up to 10MB and 50 pages. Prefer this over generic web scrapers when the source is specifically a PDF. Do not use for scanned/image PDFs (no OCR), password-protected files, or PDFs larger than 10MB.
Side effects
- PDF exceeds 10MB size limit — request rejected or truncated
- PDF requires OCR (image-only scans) — no text extracted, unbilled
- PDF is password-protected or encrypted — cannot parse, unbilled
- URL does not point to a valid PDF — non-PDF response, unbilled
- SSRF-blocked URL (private IP ranges, internal hostnames) — request rejected
- PDF has more than 50 pages — only first 50 pages returned
- Text exceeds 100K character limit — output truncated at that boundary
- URL is unreachable or returns non-200 status — fetch error
