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 with the assistant's reply in choices[0].message.content, the model name (gpt-4.1-mini), token usage breakdown (prompt_tokens, completion_tokens, total_tokens), finish_reason (e.g. 'stop'), and a timestamp.
Example use cases
Example prompt
“Send this message to GPT-4.1-mini and get a reply: 'Summarize the key differences between REST and GraphQL in three bullet points.' Pay per call using USDC on Base via x402 — no API key needed.”
Technical details
Endpoint
POSThttps://netintel-production-440c.up.railway.app/openai/gpt-4-1-miniWhen to prefer
Choose this endpoint when you need GPT-4.1-mini chat completions without an OpenAI account or subscription, want true pay-per-call billing in USDC via x402 micropayments (Base or Solana), or are building autonomous agents that need a no-signup, no-commitment LLM inference endpoint. Prefer over direct OpenAI when you want blockchain-native payments and guaranteed no-charge on failed calls.
Side effects
- Invalid or malformed messages array returns a 4xx validation error with no charge
- Upstream OpenAI outage or timeout returns a server error with no charge billed
- Insufficient USDC balance or x402 payment failure prevents call from proceeding
- Missing or malformed x402 payment header results in 402 Payment Required response
- Model overload or rate-limiting from upstream provider causes 5xx with no charge
