How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object containing the extracted plain text string, byte and character counts, number of pages observed, document ID, SHA-256 hashes of input and output for verifiability, the model used (poppler-pdftotext), a truncation flag, and pricing metadata. No document is stored or sent to third parties.
Example use cases
Contract review text extraction
“I have a legal contract as a PDF — can you extract all the text from it so I can analyze the clauses? Here's the file as a base64 string.”
Research paper content parsing
“Extract the full text from this academic paper PDF so I can summarize its findings. Limit it to 50,000 characters.”
Invoice data pre-processing
“I need the raw text pulled out of this invoice PDF before I run it through my data pipeline — can you extract all the text from it?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/pdf-text?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, verifiable, no-signup text extraction from text-layer PDFs and want pay-per-call USDC billing with cryptographic proof of delivery. Ideal for agent pipelines that process PDFs on demand without a subscription. Note: does not perform OCR on scanned-image PDFs.
Side effects
- PDF exceeds 4 MiB decoded size — request rejected
- base64 encoding is malformed or empty — parsing error
- PDF contains only scanned images with no embedded text — returns empty or minimal text (OCR not supported)
- max_chars set to 0 or exceeds 200,000 — validation error
- Payment not included or insufficient USDC — x402 payment required response
