## 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 gedx402-sqlcoder-7b-2-llm-endpoint-664704e6
```

Example prompt: Using the SQLCoder-7B-2 model, write me a SQL query that finds the top 10 customers by total order value from a table called orders with columns customer_id, amount, and created_at — allow up to 512 tokens in the response.

## When to prefer this

Choose this endpoint when you need a specialized SQL-generation model (SQLCoder-7B-2) without managing API keys, and you are comfortable paying per-call in USDC via the x402 protocol on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that need on-demand text-to-SQL conversion with crypto micropayments and no subscription overhead.

## Known failure modes

- Payment failure if USDC balance insufficient or unsupported chain used
- 402 Payment Required if x402 payment header is missing or malformed
- Invalid input if messages array is empty or missing required role/content fields
- max_tokens out of range (must be 1–4096) returns validation error
- Model unavailable on Cloudflare Workers AI backend returns 5xx
- Malformed JSON request body returns 400
