Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 strale-regex-generate-a2ee4efc
```

Example prompt: Can you generate a regex pattern that matches all of these strings: '2024-01-15', '2023-12-01', '2022-06-30'?

## When to prefer this

Choose this endpoint when you need to automatically infer a regex pattern from example strings rather than writing one manually. Particularly useful when you have concrete examples of strings that should match but lack regex expertise, or when you need an auditable, cryptographically traceable generation record for compliance or trust purposes.

## Known failure modes

- Missing or empty test_strings parameter returns an error
- Contradictory test strings that cannot be captured by a single regex may yield an overly broad or incorrect pattern
- Invalid input format may return a 400 error
- Payment not processed correctly via x402 results in a 402 response
- Network timeout or service unavailability returns a 5xx error

## How this service works

The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.

## Output

Returns a generated regular expression pattern derived from the provided test strings, along with an audit record containing a cryptographic chain hash for traceability and trust verification.
