## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-commerce-pdf-text-extraction-cd3733d0 -d '<json body>'
```

Example prompt: Can you pull out all the text from this PDF I'm attaching — up to 200,000 characters — and give it back to me as plain text?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
