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 an OpenAI-compatible JSON object containing one or more choices, each with the assistant's message content and a finish_reason (e.g. 'stop'), plus a usage object reporting prompt_tokens and completion_tokens consumed.
Example use cases
One-off LLM call for an autonomous agent
“I need to call Kimi-K3 to classify this customer support ticket into one of these categories — billing, technical, or general — keep the response under 50 tokens, and just deduct the micropayment from my wallet automatically.”
Crypto-native chatbot without API subscription
“Build me a quick chatbot that uses Kimi-K3 for replies, pays per message in USDC on Base so I don't need to manage API keys, and allows up to 300 tokens per response.”
Ad-hoc reasoning task with budget cap
“Use Kimi-K3 to think through this logic puzzle step by step — cap the output at 500 tokens — and handle the payment automatically so I don't have to set up an account anywhere.”
Technical details
Endpoint
POSThttps://farouter.tech/v1/metered/models/kimi-k3/chat/completionsWhen to prefer
Choose this endpoint when you need Kimi-K3 specifically (strong multilingual and long-context reasoning) and want true pay-per-call billing in USDC with no API account, no subscription, and no pre-purchased credits. Prefer it over OpenAI or Anthropic direct APIs when the caller is a crypto-native agent that can handle x402 payment flows, or when avoiding account creation is a hard requirement. Use a different sibling endpoint on farouter.tech if you prefer GPT, Gemini, DeepSeek, GLM, or MiniMax instead of Kimi.
Side effects
- 402 Payment Required if wallet has insufficient USDC — the quote is returned but no charge is made
- 400 Bad Request if messages array is missing or malformed
- model not found if the model ID does not match an available metered model
- timeout or 503 if the upstream Kimi provider is unavailable
- stream connection drop if SSE streaming is enabled and the network is interrupted mid-response
