## 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 telnyx-x402-gateway-minimax-m2-7-chat-completions-5d271735 -d '<json body>'
```

Example prompt: Using the Telnyx x402 MiniMax gateway, send a chat message with the system prompt 'You are a helpful assistant' and user message 'Explain the x402 payment protocol in two sentences' — pay per request with USDC, temperature 0.7, max 1024 tokens.

## When to prefer this

Choose this endpoint when you need pay-per-request LLM inference without a subscription or API key contract, specifically when using the MiniMaxAI/MiniMax-M2.7 model and settling costs in USDC via the x402 micropayment protocol. It is ideal for crypto-native agents, dApps, or serverless workflows where usage is sporadic and subscription billing is impractical. Prefer it over traditional API providers when you want on-chain verifiable payment settlement and no monthly commitment.

## Known failure modes

- Payment failure – insufficient USDC balance or x402 payment rejected, resulting in a 402 Payment Required response
- Invalid model – any model value other than 'MiniMaxAI/MiniMax-M2.7' will be rejected since the field is const
- Message limit exceeded – submitting more than 32 messages or content exceeding 8000 characters per message triggers validation errors
- Token limit out of range – max_tokens below 512 or above 4096 returns a validation error
- Temperature out of range – values below 0 or above 2 are rejected
- Too many tools – more than 16 tool definitions causes a validation error
- Network timeout – inference latency may cause timeouts on very long generations

## How this service works

Pay USDC per request for Telnyx Inference and Audio (text-to-speech, speech-to-text) through x402.

## Output

Returns an OpenAI-compatible chat completion JSON object containing the assistant's generated message, finish reason (e.g. 'stop'), token usage breakdown (prompt, completion, total tokens), a unique completion ID, and the object type 'chat.completion'.
