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 an OpenAI-compatible chat completion structure: a choices array containing the assistant's message content and finish_reason, plus a usage object with prompt_tokens and completion_tokens counts.
Example use cases
Agent reasoning without API subscription
“I want you to use DeepSeek V4 Pro to reason through this business decision for me — should I expand to a second location this quarter? Just pay the micropayment from my USDC wallet, I don't want to sign up for anything.”
Serverless LLM for a crypto-native app
“My app needs to call DeepSeek V4 Pro to summarize user-submitted articles on demand. Use FarOut's pay-per-call setup so we never pay for idle capacity — charge each call at $0.001 USDC on Base.”
Autonomous agent one-off task
“Have the DeepSeek V4 Pro model draft a cold outreach email for my SaaS targeting mid-market CFOs — one call, pay the micropayment, no API account setup.”

Endpoint
POSThttps://farouter.tech/v1/metered/models/deepseek-v4-pro/chat/completionsWhen to prefer
Choose this endpoint when you need DeepSeek V4 Pro chat completions with zero account setup, want to pay only per successful call in USDC, or are building a crypto-native or autonomous agent that needs trustless, key-free LLM access. It is ideal for bursty or experimental workloads where a subscription would be wasteful and for agents that hold a crypto wallet and need to invoke LLM inference as a paid action.
Side effects
- Payment rejected or insufficient USDC balance — call is not charged
- Invalid or malformed message array — 400 error returned
- x402 payment handshake fails due to network issues on Base or Solana
- Model temporarily unavailable — upstream inference error
- Rate or quota limits on the underlying DeepSeek model
