How this service works
Fixed-price chat completions for minimax-m3 on FarOut: flat $0.002 per call (includes up to 4,000 input + 1,000 output tokens). Rate: $0.019/1M input tokens, $0.077/1M output tokens. Pay with USDC on Base using x402. No API key, no account, no prepaid balance.
Output
Returns an OpenAI-compatible JSON object containing one or more choices, each with an assistant message and finish reason, plus a usage block showing prompt and completion token counts.
Example use cases
Autonomous agent coding assistant
“Have the MiniMax M3 model help me write a TypeScript function that debounces API calls, keeping the output under 800 tokens — I want to pay per call from my USDC wallet, no account needed.”
Crypto-native chatbot backend
“Send this user message to MiniMax M3 and get a response: 'What are the risks of providing liquidity in a DEX?' — use up to 300 tokens and stream the reply back to me.”
Reasoning task with pay-per-use billing
“I need MiniMax M3 to reason through this logic puzzle step by step: 'If all bloops are razzles and all razzles are lazzles, are all bloops lazzles?' — give me up to 500 tokens and bill my Base wallet per request.”
Technical details
Endpoint
POSThttps://farouter.tech/v1/models/minimax-m3/chat/completionsWhen to prefer
Choose this endpoint when an autonomous agent or application needs MiniMax M3 specifically, requires pay-per-call USDC billing with no prepaid account or API key, and operates in a crypto-native or x402-compatible environment on Base. Prefer this over OpenAI or Anthropic direct APIs when you need keyless, wallet-based micropayment access to a frontier model.
Side effects
- Payment not received or insufficient USDC balance — returns 402 Payment Required
- Invalid or unsupported model ID — returns 400 Bad Request
- messages array is empty or malformed — returns 422 Unprocessable Entity
- max_tokens exceeds model context limit — returns 400 or truncated response
- Network timeout if streaming connection is dropped mid-response
