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 text, finish reason (e.g. 'stop'), token usage breakdown (prompt_tokens, completion_tokens, total_tokens), model name ('gpt-5.4-nano'), a unique completion ID, and a Unix timestamp. Output tokens are capped at 1024.
Example use cases
One-off LLM call without subscription
“I need a quick answer from GPT-5.4-nano: 'Summarize the main differences between TCP and UDP in two sentences.' Pay per call only, no signup — cap the output at 200 tokens.”
Agent reasoning step with lightweight model
“Use the nano GPT model to classify this support ticket as 'billing', 'technical', or 'general': 'I was charged twice last month and can't log into my account.' Just return the category label, limit output to 50 tokens.”
System-prompted content generation
“Send this to GPT-5.4-nano with a system prompt saying 'You are a formal business writer' and a user message saying 'Draft a one-paragraph apology email for a delayed shipment.' Keep the reply under 300 tokens.”

Endpoint
POSThttps://netintel-production-440c.up.railway.app/openai/gpt-5-4-nanoWhen to prefer
Choose this endpoint when you need a single, low-cost GPT chat completion without committing to an OpenAI subscription or API key. Ideal for agents that need occasional LLM inference steps, want pay-per-call billing in USDC, require a standard OpenAI-compatible response format, or must avoid pre-registration with providers. Not ideal for high-volume inference (per-call overhead adds up), streaming responses, or completions longer than 1024 tokens.
Side effects
- Input exceeds ~24000 character limit — request rejected, no charge
- max_completion_tokens exceeds 1024 — capped or rejected
- Malformed messages array (missing role or content) — validation error, no charge
- Upstream OpenAI API failure — server error returned, no charge
- x402 payment failure or insufficient USDC balance — payment rejected before execution
- Invalid bodyType enum value — request rejected
