```

Example prompt: Can you explain what this regex pattern does in plain English: ^(\d{3})-?(\d{3})-?(\d{4})$?

## When to prefer this

Choose this endpoint when an AI agent or developer needs a quick, deterministic, pay-per-call explanation of a regex pattern without signing up for an account or managing API keys — ideal for one-off lookups, embedded agent workflows, or situations where USDC micropayments via x402 on Base are already in use.

## Known failure modes

- Missing or empty schema parameter returns an error or empty explanation
- Malformed or syntactically invalid regex may produce an error or an explanation of the error
- Payment failure via x402 returns HTTP 402 and no result
- Rate limiting or worker timeout may return 503 or 504
- Very complex or extremely long regex patterns may exceed processing limits
