## 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 sql-query-explainer-plain-english-4cae56c5 -d '<json body>'
```

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, private, plain-English explanation of a SQL query without sending data to a third-party cloud LLM. Especially useful for sensitive database schemas or proprietary queries that shouldn't leave your environment. Prefer this over generic chat LLMs when you want a pay-per-call, no-subscription model with local inference.

## Known failure modes

- Empty or missing query body returns a generic error or empty explanation
- Malformed SQL may produce a confused or hallucinated explanation without flagging syntax errors
- Very long queries may be truncated or produce incomplete explanations
- Cloudflare tunnel may be offline or rate-limited, returning 402 or 5xx
- Payment failure (insufficient USDC or x402 protocol mismatch) blocks the request

## How this service works

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

## Output

A plain-English narrative explanation of the SQL query — describing what tables are involved, what filtering and joining is happening, what the query returns, and the overall intent — suitable for non-technical readers or documentation purposes.
