## 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 farout-minimax-m3-chat-completions-x402-pay-per-call-b4870571 -d '<json body>'
```

Example prompt: Send a chat message to MiniMax-M3 asking it to summarize the following paragraph in two sentences, and pay for the call in USDC on Base: 'Quantum computing leverages quantum mechanical phenomena such as superposition and entanglement to perform computations that classical computers find intractable, potentially revolutionizing fields like cryptography and drug discovery.'

## When to prefer this

Choose this endpoint when you need MiniMax-M3 specifically and want pay-per-request billing in USDC with no API key, account, or subscription — ideal for agents running infrequent or unpredictable inference workloads, prototyping, or situations where account management is impractical. Prefer alternatives if you need high-volume throughput (where a subscription is cheaper), streaming responses, or a different frontier model.

## Known failure modes

- Payment rejected or insufficient USDC balance — call not executed and not charged
- Invalid or malformed message array — 400 error returned
- Model temporarily unavailable — 503 or gateway error
- x402 payment flow not supported by client — 402 response with payment details returned but not fulfilled
- Rate limiting or network timeout on farouter.tech infrastructure

## How this service works

Pay-per-call LLM inference over x402. Frontier models (GLM, GPT, Gemini, Kimi, DeepSeek, MiniMax) billed per request in USDC on Base or Solana mainnet. No API key, no account. The 402 quotes your exact request; failed calls are never charged.

## Output

A JSON object containing the assistant's reply text under choices[0].message.content, the finish_reason (e.g. 'stop'), and a usage object with prompt_tokens and completion_tokens counts.
