## 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 24k-labs-regex-from-text-b8c3b6f8 -d '<json body>'
```

Example prompt: Can you generate a regex that matches US phone numbers in the format (123) 456-7890 or 123-456-7890, and explain what each part does?

## When to prefer this

Use this endpoint when you need to quickly generate a regex from a natural language description without writing it by hand. Ideal for developers, automation agents, or non-technical users who know what they want to match but don't know regex syntax. Prefer this over asking a general-purpose LLM when you want a structured, consistent API response with both the pattern and an explanation bundled together at a fixed low cost.

## Known failure modes

- Description is too vague or ambiguous — may produce a regex that partially matches or over-matches
- Description references a language-specific regex flavor that differs from the one generated
- Extremely complex patterns may be incomplete or incorrect — should be validated before production use
- Non-English or very technical input may reduce generation quality

Generate a regular expression from a plain-English description, with a short explanation.

## Output
