How this service works
OpenAI-compatible chat completions over x402, answered by Claude Sonnet 4.6 — send a messages array and get an assistant reply for Q&A, reasoning, agent planning, coding help, summarization, extraction, and classification. Body is OpenAI chat.completions-shaped ({model?, messages:[{role,content}], max_tokens?, temperature?}); response is a chat.completion object. Flat $0.06; inputs capped ~6KB, max_tokens 1024; no streaming in v1.
Output
Returns an OpenAI-compatible chat.completion object containing: one or more choices with the assistant's reply text and a finish_reason (stop, length, content_filter, or tool_calls), a Unix timestamp, the model name, a unique completion ID, and a usage object with prompt_tokens, completion_tokens, and total_tokens counts.
Example use cases
Example prompt
“Ask Claude Sonnet: 'Summarize the key differences between TCP and UDP in plain English' — use a temperature of 0.7 and limit the response to 512 tokens.”
Technical details
Endpoint
POSThttps://netintel.dev/messagesWhen to prefer
Choose this endpoint when you need one-off or low-volume Claude Sonnet inference without committing to an Anthropic subscription or API key — ideal for agents that pay per call via x402 USDC micropayments on Base mainnet. Prefer this over direct Anthropic API when you want usage-based billing with no setup, or when operating in a micropayment-native agentic stack. Not suitable for streaming responses, tool/function calling, or completions requiring more than 1024 output tokens.
Side effects
- Payment not included or insufficient USDC — 402 Payment Required
- Messages array missing or empty — 400 Bad Request
- Unsupported model name specified — 400 or fallback to default
- max_tokens exceeds cap of 1024 — silently capped or error
- Malformed message role (not system/user/assistant) — 400 Bad Request
- Upstream Anthropic API unavailability — 502 or 503
- Rate limit exceeded — 429 Too Many Requests
