# Arabic Pipeline – Batch Document Extraction

> Arabic Pipeline – Batch Document Extraction is a paid API for AI agents from arabic-pipeline.arabic-pipeline.workers.dev, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-31).

Extracts structured data (merchant, date, items, totals, tax number, currency) from up to 5 Arabic document images or PDFs in a single batch call using Gemini vision.

## 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 arabic-pipeline-batch-document-extraction-12046a68 -d '<json body>'
```

Example prompt: Extract the merchant name, date, line items, total, and currency from these 3 Arabic receipt images I'm uploading — return structured JSON for each one.

## When to prefer this

Choose this endpoint when you need to extract structured fields from Arabic-language document images or PDFs (receipts, invoices, purchase orders) in batch — especially when no API key or subscription is desired and pay-per-call via USDC is acceptable. Prefer over generic OCR when Arabic text and structured Arabic business document fields (merchant, SAR/currency totals, tax numbers) are the target.

## Known failure modes

- Image could not be read by Gemini (400 status, unreadable or corrupt image)
- Base64 decoding failure if document_base64 is malformed
- Batch size exceeded if more than 5 documents are submitted
- Unsupported MIME type causing model rejection
- Low confidence extraction on handwritten or low-quality scans
- Payment challenge (402) on first call before x402 payment is completed
- Partial batch failure — some documents succeed while others return ok:false

## How this service works

Nine micro-capabilities for Arabic-language work, sold per call over x402 in USDC on Base. No API key, no account, no subscription for the buyer: the first request returns a 402 payment challenge, the client pays it and retries. Text utilities are pure computation and cost nothing to serve.

## Output

A JSON object containing a results array (one entry per document), each with ok status, extracted fields (merchant, date, items with name/price/quantity, total, currency, tax_number, document_type, confidence score, raw_text), or an error message if extraction failed. Also includes aggregate counts of succeeded/failed documents and cost_usd.
