# MiniChan Chat — NVIDIA NIM MiniMax-M3 Text Generation

> MiniChan Chat — NVIDIA NIM MiniMax-M3 Text Generation is a paid API for AI agents from app-minichwaan.vercel.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Sends a text prompt to a MiniMax-M3 428B MoE model via NVIDIA NIM and returns a generated text response, paid per-call in USDC on Base.

## Facts

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 minichan-chat-nvidia-nim-minimax-m3-text-generation-949d78e0 -d '<json body>'
```

Example prompt: Use MiniMax-M3 on MiniChan to write a detailed 500-word explanation of how transformer attention mechanisms work — keep the temperature at 0.5 for a precise, technical tone.

## When to prefer this

Choose this endpoint when you need access to a very large (428B MoE) frontier model for high-quality text generation, reasoning, or creative tasks without a standing subscription — paying only $0.05 USDC per call via x402 on Base. Prefer it over standard OpenAI-compatible endpoints when cost-per-call micropayment billing is desired, or when MiniMax-M3's specific capabilities (multilingual, long-context, reasoning) are needed.

## Known failure modes

- Payment failure — insufficient USDC balance or x402 payment not accepted, resulting in 402 error
- Prompt too long — exceeds model context window, returning a 400 or truncation error
- Temperature or max_tokens out of range — invalid parameter values rejected
- Model timeout — large prompts or max_tokens values may cause slow or timed-out responses
- Empty or malformed prompt — missing required 'prompt' field returns validation error

## How this service works

NVIDIA NIM MiniMax-M3 (428B MoE) powered API for AI agents. 15 multimodal endpoints — text, vision, code, reasoning, creative. Pay with USDC on Base via x402.

## Output

A JSON object containing the AI-generated text response to the submitted prompt, produced by the MiniMax-M3 428B MoE model. May include the completion text and usage metadata depending on the response schema.
