Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 yiduochan-minimax-inference-fa83d6f7 -d '<json body>'
```

Example prompt: Ask MiniMax-M3 to summarize this 500-page legal document I just uploaded — use up to 4000 output tokens and keep the temperature at 0.2 for a factual, low-creativity response.

## When to prefer this

Choose this endpoint when you need OpenAI-compatible LLM inference without account creation or API key management, especially for one-off or infrequent calls paid with USDC micropayments. It is ideal for agents that need MiniMax-M3's massive 1,048,576-token context window for long-document tasks, or MiniMax-M2.7 for general chat and coding loops. Prefer it over standard API providers when you want pay-per-call economics with no subscription, or when integrating crypto-native payment flows via x402.

## Known failure modes

- Payment not included or malformed x402 header — returns 402 Payment Required
- Insufficient payment amount — transaction rejected
- Invalid or unsupported model ID — returns 400 Bad Request
- Messages array missing required role or content fields — returns 400
- Context length exceeds model window — returns 400 or truncation error
- Network timeout for very long completions with large max_tokens
- Balance exhausted mid-session — subsequent calls require new payment

## How this service works

OpenAI-compatible LLM inference, paid per call. POST a standard chat completion body with an x402 payment and the response is the completion itself; the API key and remaining balance come back in headers, so the next call can skip payment. Serves MiniMax language models: MiniMax-M3 for long-context reasoning with a 1,048,576-token window, and MiniMax-M2.7 for general chat, agent loops and coding. Text to speech and video generation run on the same balance. Whatever a call does not spend stays on the paying wallet. No account, email or signup.

## Output

Returns the full OpenAI-compatible chat completion response body containing the generated text. Response headers include a freshly issued API key and the remaining balance, allowing the caller to skip the x402 payment on subsequent requests until the balance is depleted.
