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 text inside choices[0].message.content, a finish_reason ('stop'), the model used (claude-sonnet-4-6), token usage breakdown (prompt_tokens, completion_tokens, total_tokens), a unique completion ID, and a Unix timestamp. No streaming — single synchronous response.
Example use cases
Example prompt
“Ask the NetIntel AI chat endpoint 'What is the capital of France?' and give me back the assistant's reply along with how many tokens were used — pay the per-call fee in USDC automatically.”
Technical details
Endpoint
POSThttps://netintel-production-440c.up.railway.app/messagesWhen to prefer
Choose this endpoint when you need a pay-per-call AI chat completion with no signup, no API keys, and automatic no-charge on failed calls. Ideal for agents that want to query Claude on-demand using USDC micropayments on Base mainnet via x402, especially in agentic pipelines where predictable per-call billing and zero-friction onboarding matter. Prefer over traditional OpenAI/Anthropic direct APIs when you need crypto-native payment rails without subscription overhead.
Side effects
- Input validation rejection — returns error without charge if message format is invalid
- Upstream model failure — no charge on server or provider errors
- Payment failure — x402 micropayment not completed, request not processed
- Malformed request body — missing required messages field
- Rate or quota issues on upstream Claude provider

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
