GPT API & OpenAI Responses gateway
Latest GPT, Responses and Chat Completions through one endpoint.
Use the latest GPT API, the OpenAI Responses API and Chat Completions through a single reliable gateway. Built for coding tools, agents and production apps that need stable, affordable access.
Stable and cost-effective
Multi-channel routing and automatic failover smooth out upstream hiccups, while plans and wallet billing keep per-request cost transparent.
Drop-in for existing OpenAI SDKs
Set the base URL and key — most OpenAI SDKs and tools work unchanged, so integration is a config change, not a rewrite.
Do you support the OpenAI Responses API?
Yes. Both /v1/responses and /v1/chat/completions are supported so you can adopt the Responses API gradually.
Will my existing OpenAI code work?
In most cases yes — point the base URL and API key at the gateway and keep your SDK and request shapes.
How do I control cost?
Pick a subscription plan or bill from wallet balance; usage logs report tokens and cost for every request.
