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 JSON chat completion object containing: a unique completion ID, the model name (gpt-4o-mini), the assistant's reply text inside choices[0].message.content, finish_reason (e.g. 'stop'), and a usage block with prompt_tokens, completion_tokens, and total_tokens.
Example use cases
Keyless LLM in an agent pipeline
“I need to call GPT-4o-mini from my automation script without storing an API key — can you run this prompt through the pay-per-call chat completions endpoint: 'Summarize the following support ticket in one sentence: customer says checkout keeps failing on mobile.'”
One-off AI answer for a user query
“My user just asked 'What's the difference between USDC and USDT?' — fire that off to the AI chat completions endpoint and return the answer, billing me the $0.10 per-call fee in USDC.”
Prototyping a chatbot without a subscription
“I'm testing a chatbot idea and don't want to set up an OpenAI account yet — can you send 'You are a friendly cooking assistant. User: How do I make a roux?' to the chat completions endpoint and show me what comes back?”

Endpoint
POSThttps://netintel-production-440c.up.railway.app/api/v1/chat/completionsWhen to prefer
Choose this endpoint when you need OpenAI-compatible chat completions without managing API keys or subscriptions, want transparent pay-per-call USDC billing (no failed-call charges), and are building on an x402-enabled agent stack using Base or Solana mainnet. Ideal for sporadic or low-volume LLM calls where a monthly subscription is wasteful, or for agents that need to self-fund inference costs autonomously.
Side effects
- Invalid or malformed messages array — returns 4xx validation error, no charge
- Upstream OpenAI service unavailable — returns server error, no charge per NetIntel policy
- Malformed JSON request body — rejected at input validation, no charge
- Model name not recognized — validation rejection, no charge
- x402 payment not included or insufficient — payment required error before processing
