## 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 x402-gateway-production-up-railway-app-92077f5c -d '<json body>'
```

Example prompt: Use the MiniMax efficient model to write a concise product description for a wireless ergonomic keyboard — fast, affordable output is fine, no need for a top-tier model.

## When to prefer this

Choose this endpoint when you need fast, affordable LLM inference for everyday tasks and cost efficiency matters more than maximum capability. Ideal for high-volume, routine text generation, summarization, or Q&A where a frontier model would be overkill. Prefer over heavier models (DeepSeek reasoner, Cohere Command) when latency and per-call cost are primary constraints. Best suited for agents making frequent small LLM calls within a x402 micro-payment workflow.

## Known failure modes

- Payment not included or insufficient USDC balance — x402 payment verification fails, request rejected
- Invalid or malformed prompt/message format — 400 Bad Request
- MiniMax backend unavailable or rate-limited — 503 or timeout
- x402 gateway itself down — connection error to railway.app host
- Prompt exceeds model context window — truncation or error response

## How this service works

MiniMax's efficient model — fast and affordable for everyday tasks

## Output

Returns a text completion or conversational response generated by MiniMax's efficient language model. The response typically includes the generated text content and may include token usage metadata. Payment of $0.01 USDC is charged per call via the x402 protocol.

## Example request

```json
{
 "model": "minimax",
 "messages": [
  {
   "role": "user",
   "content": "Generate a short product description for a wireless ergonomic keyboard in 2-3 sentences."
  }
 ],
 "max_tokens": 100
}
```
