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 a standard OpenAI chat.completion JSON object containing the assistant's reply message, finish reason (e.g. 'stop'), model used, and token usage breakdown (prompt_tokens, completion_tokens, total_tokens). The choices array holds the generated message content.
Example use cases
Agent reasoning step via LLM
“Using the NetIntel chat completions endpoint with gpt-4o, send this system prompt: 'You are a helpful data analyst.' and this user message: 'Given quarterly revenue of $1.2M and expenses of $980K, what is the net profit margin?' — pay with USDC via x402.”
Keyless LLM call for startup prototype
“I don't have an OpenAI API key set up yet — can you call the NetIntel chat completions API with gpt-4o-mini, send the user message 'Write a one-paragraph product description for a reusable silicone food wrap', and bill it per-call in USDC?”
LLM-powered classification in pipeline
“Send this to gpt-4o via the NetIntel x402 chat completions endpoint — system: 'You classify support tickets into: billing, technical, or general.' user: 'My invoice shows a double charge from last month.' — return the category and a short explanation.”

Endpoint
POSThttps://netintel-production-440c.up.railway.app/v1/chat/completionsWhen to prefer
Choose this endpoint when you need OpenAI-compatible chat completions without signing up for an API key or committing to a subscription — ideal for autonomous agents that pay per call in USDC via x402 on Base or Solana. Prefer it over direct OpenAI when you want per-call billing with automatic no-charge on failures, or when operating in a crypto-native payment environment.
Side effects
- Invalid model ID returns validation error (not billed)
- Malformed messages array or missing required fields returns input-validation rejection (not billed)
- Upstream OpenAI failure returns server error (not billed per NetIntel policy)
- Insufficient USDC balance or x402 payment failure blocks the call
- max_tokens clamped silently to model's cap if exceeded
