## 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-text-chunker-b037ccfc -d '<json body>'
```

Example prompt: Split this Arabic text into chunks of at most 500 characters each with a 50-character overlap between consecutive chunks: 'الذكاء الاصطناعي هو محاكاة للعمليات الذكاء البشري...'

## When to prefer this

Choose this endpoint when you need a pay-per-call, no-registration Arabic text chunker with configurable chunk size and overlap, especially when building RAG pipelines, embedding workflows, or semantic search indexes over Arabic content. Prefer it over general-purpose chunkers when the text is primarily Arabic and you want fine-grained control over chunk boundaries via character counts.

## Known failure modes

- Text exceeds processing limits — max_chars must be between 1 and 8000
- Invalid overlap value — overlap must be a non-negative integer
- Missing required 'text' field returns validation error
- Non-Arabic or mixed-script text may produce unexpected chunk boundaries
- 402 Payment Required on first call — client must complete x402 USDC payment challenge before retrying
- Network timeout on Cloudflare Worker if text payload is extremely large

## 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

Returns a JSON object containing an array of chunk objects (each with index, start offset, end offset, and text), a total chunk count, total character count, the endpoint name, and the cost in USD ($0.002 per call).
