## 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-workers-ai-reasoning-chat-d88a0df7
```

Example prompt: Using the pay-per-call reasoning model (no API key needed, pay 0.08 USDC), send this conversation to DeepSeek R1: system message 'You are a helpful assistant', user message 'Explain why the sky is blue step by step', and limit the reply to 512 tokens.

## When to prefer this

Choose this endpoint when you need a reasoning-capable LLM (DeepSeek R1) with no API key or account registration, want to pay per-call in USDC on Base, Polygon, Arbitrum, World, or Solana, or are building crypto-native agents that need permissionless AI access. Prefer it over OpenAI or Anthropic when avoiding monthly subscriptions or API key management overhead.

## Known failure modes

- Payment not received or insufficient USDC — 402 Payment Required response
- Invalid message format (missing role or content fields) — 400 Bad Request
- max_tokens out of range (below 1 or above 4096) — validation error
- Network or Workers AI backend unavailability — 500/503 error
- Unsupported blockchain/wallet for USDC payment — payment rejected
