## 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-ce58a495 -d '<json body>'
```

Example prompt: Can you check the grammar of this sentence and fix any mistakes: 'She don't know where is the keys that she left yesterday on the table'?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-use grammar check without committing to a subscription-based NLP service. Ideal for AI agents that occasionally need grammar validation as part of a larger workflow, especially when integrated with x402 micropayment infrastructure for cost-effective per-request billing.

## Known failure modes

- Missing required 'text' field returns validation error
- Empty string may return an error or trivial success response
- Extremely long text may be truncated or rejected
- Non-English text may produce inaccurate or unexpected results
- Service unavailability returns HTTP 402 or 5xx if payment fails
