How this service works
125 production APIs behind HTTP 402 micropayments. 87 LLMs, Kling V3 and Hailuo video generation, image generation, code execution, travel search, web scraping, TTS, and transaction simulation. Pay with USDC on Base, USDm on MegaETH, or USDC on Solana.
Output
Returns an OpenAI-compatible JSON object with a choices array containing the assistant's message, finish reason, and model identifier. Optionally streams SSE tokens if streaming is enabled. The top-level 'content' field mirrors the first choice's message content for convenience.
Example use cases
Multilingual customer support drafting
“Use MiniMax M3 to draft a polite reply to this customer complaint in both English and Mandarin: 'My order arrived three days late and was damaged.'”
Tool-calling agent reasoning step
“Send this tool-calling message to MiniMax M3 — system: 'You are a data analyst assistant', user: 'What is the revenue trend for Q3?', and include a function definition called get_revenue_data that takes a quarter string parameter.”
Streaming creative writing generation
“Ask MiniMax M3 to write a short sci-fi story opening (about 150 words) about a lone astronaut discovering an alien signal, and stream the response back as it's generated.”

Endpoint
POSThttps://x402engine.app/api/llm/minimax-m3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically want to run inference on MiniMax M3 (a state-of-the-art Chinese-origin frontier model) without managing API keys or subscriptions, paying only per call in USDC or USDm. Ideal for agents that need occasional or bursty LLM access with OpenAI-compatible message formats, tool calling, and optional streaming, billed at a fixed $0.003488 per call.
Side effects
- Payment not settled — 402 response if USDC/USDm micropayment fails
- Invalid messages format — missing required 'messages' array causes 400 error
- Unsupported sampling parameter for MiniMax M3 — ignored or error depending on capability
- Token limit exceeded — model may truncate or return an error
- Streaming interrupted — SSE connection dropped mid-response
