## 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 ged-x402-chat-fast-workers-ai-llm-via-crypto-payment-c712a657
```

Example prompt: Ask the AI assistant 'What are three tips for writing clean Python code?' using up to 512 tokens, and pay the $0.005 USDC fee on Base — no API key needed.

## When to prefer this

Choose this endpoint when you need a fast, low-cost LLM chat completion with no API key or account signup, and you can pay $0.005 USDC per call on-chain via x402 on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents operating in crypto-native environments or where traditional API credentials are unavailable. Best suited for short, rapid inference tasks using Llama 3.2 1B Instruct; for larger models or higher-quality output, look elsewhere.

## Known failure modes

- Payment not provided or insufficient USDC — returns HTTP 402 Payment Required
- Invalid message format or missing required role/content fields — returns 400 Bad Request
- max_tokens out of range (below 1 or above 4096) — validation error
- Unsupported payment network — payment rejected by x402 facilitator
- Model inference timeout — Workers AI backend latency spike
- Malformed JSON body — parse error response
