## 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-metrics-60e61aa8
```

Example prompt: Can you count the words, characters, and tokens in this Arabic text: 'مرحباً بكم في المملكة العربية السعودية'?

## When to prefer this

Choose this endpoint when you need fast, pay-per-call Arabic text measurement with no account setup — ideal for agents that process Arabic content occasionally and want to avoid subscription overhead. Prefer it over general-purpose NLP APIs when Arabic-specific tokenization accuracy matters and you want micropayment billing via USDC on Base.

## Known failure modes

- Missing 'text' field in request body returns a 400 error
- Payment challenge (HTTP 402) returned on first call before USDC payment is made via x402 protocol
- Empty string input may return zero-value metrics or a validation error
- Non-Arabic or mixed-language text may yield inaccurate word/token counts if tokenization is Arabic-specific

## 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 text metrics for the submitted Arabic string, typically including character count, word count, and token-level statistics useful for estimating processing costs or validating content length constraints.
