How this service works
Pay-per-call LLM inference over x402. Frontier models (GLM, GPT, Gemini, Kimi, DeepSeek, MiniMax) billed per request in USDC on Base or Solana mainnet. No API key, no account. The 402 quotes your exact request; failed calls are never charged.
Output
Returns a JSON object with a choices array containing the assistant's reply message, finish reason (e.g. 'stop'), and a usage object with prompt_tokens and completion_tokens counts. The response follows the standard OpenAI chat completions format.
Example use cases
On-demand AI summarization for agents
“Use DeepSeek-V4-Flash to summarize this article in three bullet points: 'The Federal Reserve held interest rates steady today, citing concerns about persistent inflation and mixed signals from the labor market.' — charge my crypto wallet per call, no API key.”
Autonomous agent reasoning step
“I need my agent to decide the next action in a workflow — send this reasoning prompt to DeepSeek-V4-Flash: 'Given the user wants to book a flight and a hotel, what should I do first?' and pay the $0.001 USDC fee per request.”
Rapid Q&A without an LLM subscription
“Ask DeepSeek-V4-Flash: 'What are the main differences between supervised and unsupervised machine learning?' — I want to pay per call in USDC on Base instead of maintaining an API account.”
Technical details
Endpoint
POSThttps://farouter.tech/v1/metered/models/deepseek-v4-flash/chat/completionsWhen to prefer
Choose this endpoint when you need DeepSeek-V4-Flash chat completions and want true pay-per-call billing in USDC via x402 with no API key, no subscription, and no account — ideal for autonomous agents or occasional inference workloads where pre-paying for tokens or managing API credentials is impractical. Prefer alternatives if you need streaming responses, very high throughput, or a model other than DeepSeek-V4-Flash.
Side effects
- Payment failure: x402 micropayment rejected or wallet has insufficient USDC — call is not charged and request is not processed
- Model unavailable: DeepSeek-V4-Flash endpoint down or overloaded — returns server error
- Malformed request: missing or invalid messages array — returns 400 bad request
- Network timeout: inference takes too long — connection dropped, no charge if payment not settled
- Invalid x402 payment header — 402 response with a fresh payment quote returned instead of completion
