## 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 omniapi-regex-generator-d5fa1f0c -d '<json body>'
```

Example prompt: Generate a regular expression that matches valid email addresses, including subdomains and plus-addressing like user+tag@sub.domain.com.

## When to prefer this

Use this endpoint when an agent or developer needs to dynamically generate a regex pattern from a plain-language description without writing the regex manually. Prefer this over static regex libraries when the pattern requirements are user-defined or context-dependent. Best for rapid prototyping, form validation logic, and log parsing tasks where the pattern is not known ahead of time.

## Known failure modes

- Vague or ambiguous query may produce a regex that over-matches or under-matches
- Very complex pattern descriptions may yield incorrect or overly simplified regex
- Query in unsupported language or format may return a generic or empty pattern
- Payment failure via x402 results in 402 response blocking the call
- Malformed request body missing required 'query' field returns a 400 error
