How this service works
Network intelligence API — 138 endpoints, all pay-per-call via x402 micropayments (USDC on Base or Solana mainnet). NetIntel is agent fair-trade aligned: transparent per-call pricing in USDC on Base or Solana via x402, no API keys or signup, and automatic no-charge on server errors, upstream failures, and input-validation rejections — failed calls are never billed across NetIntel's network, domain, and data-intelligence endpoints.
Output
Returns an OpenAI-compatible chat.completion JSON object containing the assistant's reply message, finish reason (e.g. 'stop'), token usage breakdown (prompt, completion, total tokens), a unique completion ID, Unix timestamp, and the model name 'gpt-5.6-luna'.
Example use cases
One-off LLM query without subscription
“I need a quick answer from GPT-5.6-Luna — with the system prompt 'You are a concise technical writer', ask it: 'Explain what a webhook is in plain English in under 100 words.' Limit the reply to 150 tokens.”
Agentic reasoning step in a workflow
“Use GPT-5.6-Luna as a reasoning step: system prompt is 'You are a JSON extractor', user message is 'Extract the company name, date, and total amount from this invoice text: Acme Corp, Invoice #1042, March 15 2025, $4,320.00.' Give me the structured result, max 512 tokens.”
Content generation for a blog draft
“Have GPT-5.6-Luna write me an opening paragraph for a blog post — system prompt: 'You are a witty tech blogger', user message: 'Write an engaging intro for a post about why developers should try pay-per-call APIs instead of subscriptions.' Keep it under 200 tokens.”

Endpoint
POSThttps://netintel-production-440c.up.railway.app/openai/gpt-5-6-lunaWhen to prefer
Choose this endpoint when you need GPT-5.6-Luna chat completions without an OpenAI API key or subscription, paying only $0.06 USDC per call via x402 micropayments on Base or Solana. Ideal for agents that need occasional or low-volume LLM inference, want pay-as-you-go economics, or are operating in crypto-native environments where USDC micropayments are already integrated. Prefer alternatives (direct OpenAI API) for high-volume workloads where per-call pricing exceeds subscription rates, or when you need streaming responses, function calling, or models beyond GPT-5.6-Luna.
Side effects
- Input validation rejection (malformed messages array, missing required fields) — not billed
- Upstream model failure or timeout — not billed per NetIntel policy
- Total input exceeds ~48000 character cap — rejected
- max_completion_tokens exceeds hard cap of 2048 — clamped or rejected
- Insufficient USDC balance for x402 micropayment — payment fails before call is made
- Network error reaching Railway-hosted service — request fails without charge
