How this service works
OpenAI-compatible chat completions gateway — standard /v1/chat/completions path and request shape, model chosen in the body: any gpt-* chat model (not Claude/embeddings), each at its own price. Priced per model, $0.005–$0.65 per call in USDC via x402, no API key: POST unpaid and the 402 quotes your model's exact price. Supports response_format json_object. GET /v1/models (free) lists every model with its endpoint and price.
Output
Returns a standard OpenAI chat completion object with a choices array containing the assistant's message, a model field, usage token counts (prompt_tokens, completion_tokens, total_tokens), and a unique completion ID — identical in shape to the OpenAI /v1/chat/completions response.
Example use cases
One-off LLM call without subscription
“I need to call gpt-4o to classify this support ticket as 'billing', 'technical', or 'general' — I don't have an OpenAI account, just pay the $0.10 per call with USDC. Ticket: 'My invoice this month looks wrong, I was charged twice.'”
Agent pipeline LLM reasoning step
“Use gpt-4.1 to extract all action items from this project update email and return them as a JSON list — pay per call, no API key needed: 'Alice will finalize the spec by Friday, Bob needs to review the staging deploy, and Carol should send the client the revised proposal.'”
Cheap nano-model summarization at scale
“Summarize this product review in one sentence using gpt-4o-mini — keep max_tokens at 60 to keep it short: 'This blender is incredibly powerful, handles ice and frozen fruit with ease, but the lid pops off occasionally at high speed which is a bit worrying.'”
Technical details
Endpoint
POSThttps://netintel.dev/v1/chat/completionsWhen to prefer
Choose this endpoint when you need OpenAI-compatible chat completions without setting up an OpenAI account or managing API keys — especially useful in agent pipelines that pay per invocation using x402/USDC micropayments. Prefer it over the model-specific sibling endpoints (e.g. /v1/gpt-4.1) when you want a single flexible endpoint that selects the model via the request body. Avoid if you need streaming responses, function calling, or vision inputs not confirmed supported here.
Side effects
- Payment not included or insufficient USDC — returns 402 Payment Required
- Unsupported model ID — returns 400 with model not found error
- Messages array missing required role or content fields — returns 400 validation error
- max_tokens exceeds model cap — clamped silently or returns 400
- Model capacity exceeded or upstream OpenAI timeout — returns 503 or 504
- Malformed JSON body — returns 400 parse error
