## 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-qwen3-30b-a3b-fp8-llm-via-x402-eab42e19
```

Example prompt: Ask the Qwen3-30B model (via the x402 pay-per-call service, no API key needed) to explain the difference between supervised and unsupervised learning in 3 paragraphs — use a system message saying 'You are a helpful ML tutor' and cap the reply at 800 tokens.

## When to prefer this

Choose this endpoint when you need a large (30B parameter) open-weight language model with no API key or account registration, paying per-call in USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that need on-demand LLM inference with crypto-native micropayment billing and no monthly subscription commitment.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required returned
- Invalid message array structure or missing required role/content fields — 400 Bad Request
- max_tokens exceeds 4096 — validation error
- Network timeout if inference takes too long on large prompt
- Unsupported blockchain for payment — payment rejected

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.

## Output

A JSON object containing the model name ('model': '@cf/qwen/qwen3-30b-a3b-fp8') and the assistant's generated text ('response': string), billed at $0.008 USDC per call.
