## 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 bolt-grammar-checker-b392d245 -d '<json body>'
```

Example prompt: Can you check the grammar in this sentence and fix any mistakes: 'She dont know what she is doing yesterday at the office'?

## When to prefer this

Choose this endpoint when you need quick, pay-per-use grammar checking without a subscription, especially within an AI agent workflow that already uses x402 USDC micropayments. Ideal for lightweight grammar validation of short-to-medium text snippets as part of a larger automated pipeline.

## Known failure modes

- Missing required 'text' field returns validation error
- Empty string input may return no corrections or an error
- Very long text strings may hit length limits
- Malformed JSON body returns 400 error
- Payment failure via x402 results in 402 response before processing
