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 response containing a choices array with the assistant message content and finish reason, plus a usage object showing prompt_tokens and completion_tokens consumed for the request.
Example use cases
Agentic task with no API subscription
“I need you to answer 'Summarize the key differences between REST and GraphQL in two sentences' using the FarOut GPT-5.6 Solana endpoint — just pay the micropayment from my wallet and give me the response, no API key setup needed.”
One-off code generation snippet
“Ask GPT-5.6 via FarOut to write me a Python function that validates an email address — use the Solana pay-per-call option so I'm only charged for this single request.”
Cost-controlled multi-step reasoning
“Run this reasoning prompt through FarOut's GPT-5.6 Solana model: 'List three pros and cons of microservices architecture' — I want to pay per call in USDC so I can track exact inference costs without a monthly subscription.”
Technical details
Endpoint
POSThttps://farouter.tech/v1/metered/models/gpt-5.6-sol/chat/completionsWhen to prefer
Choose this endpoint when you need GPT-5.6 chat completions without an OpenAI account or API key, want true pay-per-call billing settled in USDC on Solana, or are building an autonomous agent that must pay for AI inference atomically via x402 without pre-purchasing credits. Prefer it over standard OpenAI API when avoiding subscription lock-in or when operating in a crypto-native payment environment.
Side effects
- Payment insufficient or wallet balance too low — 402 response with exact price quote, request not charged
- Invalid or malformed messages array — 400 error returned
- Model temporarily unavailable — 503 or provider-side error
- Solana network congestion causing payment confirmation delay
- Max tokens exceeded for the model context window
- Request times out before completion — caller not charged per the no-charge-on-failure guarantee
