## 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-90852a90 -d '<json body>'
```

Example prompt: Can you check the grammar of this sentence and tell me what needs to be fixed: 'She don't know nothing about the plans we was making yesterday'?

## When to prefer this

Use this endpoint when an AI agent needs to programmatically validate or correct grammar in a piece of text as part of a writing, editing, or content pipeline workflow, especially when per-request micropayment via USDC x402 is acceptable and no OAuth setup is desired.

## Known failure modes

- Missing required 'text' field returns a validation error
- Empty string input may return no corrections or an error
- Very long text may be truncated or time out
- Non-English text may yield inaccurate or no results
- Network or payment failure (402 not satisfied) blocks the request
