```

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 o.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 quick, affordable plain-English breakdown of a SQL query without setting up a full LLM pipeline. It is ideal for developer tools, documentation generators, onboarding workflows, or any agent that needs to surface SQL logic to non-technical users. At $0.01 per call it is cost-effective for high-volume use cases where SQL explanation is a recurring need.

## Known failure modes

- Missing or empty SQL query in message — returns an error or unhelpful response
- Extremely complex or nested queries may produce incomplete or partially accurate explanations
- Non-standard SQL dialects (e.g. vendor-specific syntax) may not be fully understood
- Malformed or syntactically invalid SQL may yield an error or degraded explanation
- Rate limiting or payment failure (x402) may prevent the call from completing

## How this service works

Explain a SQL query in plain English. Paste query in message.

## Output

A natural-language explanation of the SQL query, describing what tables are accessed, what filtering or joining logic is applied, what is computed or aggregated, and what the overall result set represents — suitable for developers and non-technical audiences alike.
