## 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 primeapi-regex-generator-d6fa0504 -d '<json body>'
```

Example prompt: Generate a regex pattern that matches valid email addresses, including subdomains like user@mail.example.com.

## When to prefer this

Choose this endpoint when you need to programmatically generate a regex from a plain-English description, especially within an AI agent workflow that requires string validation or extraction patterns without a human writing the regex manually. Prefer this over static regex libraries when the pattern requirement is dynamic or user-specified.

## Known failure modes

- Ambiguous natural language description returns an overly broad or narrow pattern
- Complex or contradictory requirements may produce an incorrect regex
- Query too vague (e.g. 'match text') returns a generic or unhelpful pattern
- Service unavailable or payment failure returns a 402 or 5xx error
- Edge cases in the description may not be captured in the generated pattern
