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
Returns a JSON object containing the AI-generated text response from the MiniMax-M3 428B MoE model, based on the submitted prompt and generation parameters.
Example use cases
On-demand code generation for agents
“Ask MiniChan to write me a Python function that parses nested JSON and flattens it into a CSV — keep it under 600 tokens and use a low temperature of 0.2 so the output is deterministic.”
Creative storytelling with large MoE model
“Use MiniChan to write the opening chapter of a sci-fi short story about a rogue AI on a generation ship — I want it creative, around 900 tokens, with temperature set to 0.9.”
Complex reasoning and problem solving
“Have MiniChan reason through this logic puzzle step by step: if Alice is taller than Bob, Bob is taller than Carol, and Carol is taller than Dave, who is the shortest? Use temperature 0.3 and give me a thorough explanation.”

Endpoint
POSThttps://app-minichi.vercel.app/api/chat?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need access to a very large (428B parameter) mixture-of-experts model for high-quality reasoning, code generation, or creative tasks, and want to pay per-call in USDC without a subscription. Prefer it over smaller hosted models when task complexity demands a frontier-scale model. Particularly useful for AI agents with crypto payment infrastructure already in place.
Side effects
- Payment failure: USDC payment on Base rejected or insufficient balance, returns 402
- Prompt too long: exceeds model context window, returns error
- max_tokens out of range: invalid token count causes parameter error
- Temperature out of bounds: value outside 0-1 range may cause validation error
- Model unavailability: NVIDIA NIM backend outage causes 503 or timeout
- Empty prompt: missing required 'prompt' field causes 400 validation error
