How this service works
LLM inference API: OpenAI-compatible chat completions for 136 AI models (Claude, GPT, Gemini, Grok, DeepSeek, Qwen, Kimi, GLM), paid per call in USDC on Base with x402. No account, no API key, automatic refund if the model fails.
Output
Returns an OpenAI-compatible chat completion JSON object containing the assistant's reply text, role, finish reason (e.g. 'stop'), token usage breakdown (prompt, completion, total), model identifier ('minimax/minimax-m3'), and a unique completion ID.
Example use cases
Crypto-native LLM inference for agents
“Use MiniMax M3 to answer this question for me without needing any API account — just pay the micro-fee automatically: 'What are the top three strategies for reducing customer churn in a SaaS business?'”
Multilingual content generation
“Ask MiniMax M3 to translate and naturally rephrase this product description into fluent Mandarin Chinese: 'Our noise-cancelling headphones deliver studio-quality sound with 30-hour battery life.'”
Automated reasoning in an agent pipeline
“I need to chain MiniMax M3 into my agent workflow — send it the system prompt 'You are a JSON-only data extractor' and the user message 'Extract name, date, and amount from: Invoice from Acme Corp, March 15 2025, $4,200' and return the completion.”

Endpoint
POSThttps://agent402-arb.rosariovitale0096.workers.dev/llm/minimax-m3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need MiniMax M3 specifically (known for strong multilingual and long-context capabilities) and want a no-account, no-API-key setup using crypto micropayments. Ideal for AI agents in Web3-native pipelines that already handle x402/USDC payments, or for developers who want to experiment with MiniMax M3 without signing up for any service. Prefer alternatives (e.g. direct MiniMax or OpenRouter) if you need streaming responses, fine-tuned models, or fiat billing.
Side effects
- Payment failure if USDC balance is insufficient or x402 payment header is malformed
- 400 Bad Request if the request body does not conform to the OpenAI chat completions schema
- Model unavailable or gateway timeout if the MiniMax M3 backend is unreachable
- Rate limiting or quota errors from the underlying model provider
- Invalid bodyType or method enum causes schema validation failure at gateway level
