## 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-8d2616c9 -d '<json body>'
```

Example prompt: Can you grammar-check this sentence for me: 'She don't know nothing about the new policy changes that was announced yesterday.'

## When to prefer this

Use this endpoint when you need a quick, pay-per-use grammar check on a text string without committing to a subscription-based NLP service. Suitable for agents that need on-demand grammar validation as part of a writing pipeline at low cost ($0.03/call).

## Known failure modes

- Missing required 'text' field returns validation error
- Empty string input may return error or empty analysis
- Very long text strings may be truncated or rejected
- Payment failure via x402 returns 402 status before processing
- Malformed JSON body returns 400 error
