Example prompt: Can you explain what this SQL query does in plain English? SELECT u.name, COUNT(o.id) AS order_count FROM users u LEFT JOIN orders o ON u.id = o.user_id WHERE u.created_at > '2024-01-01' GROUP BY u.name HAVING COUNT(o.id) > 5 ORDER BY order_count DESC;

## When to prefer this

Choose this endpoint when you need a fast, affordable natural-language explanation of a SQL query — especially useful for developers onboarding to a new codebase, non-technical users trying to understand reports, or code reviewers auditing database logic. At $0.01 per call it is cost-effective for high-volume developer tooling pipelines.

## Known failure modes

- Malformed or incomplete SQL may produce a confused or inaccurate explanation
- Very large or deeply nested queries may be truncated or only partially explained
- Dialect-specific SQL (e.g. T-SQL, PL/pgSQL) may not be fully understood
- Empty or missing message body returns an error
- Network timeouts may occur if the underlying Cloudflare Tunnel is unavailable
