Access
Choose the endpoint your client expects
Use OpenAI-compatible Chat Completions, Responses-compatible, and Messages-compatible endpoints. Check whether your client asks for a full endpoint or a Base URL first.
For common Chat Completions clients
A general compatibility endpoint for SDKs, plugins, and third-party clients that speak the Chat Completions format.
https://gpt-agent.cc/v1/chat/completions- Use this when a client asks for the full endpoint
- Start here when the client type is unclear
For newer response-style clients
Use this endpoint when your client or workflow expects the Responses API shape.
https://gpt-agent.cc/v1/responses- Good for agent-style workflows
- Works well with compatible developer tools
For Messages-format clients
Use this endpoint when your client expects the Messages request shape.
https://gpt-agent.cc/v1/messages- Messages-compatible clients
- Use the full endpoint when required
Base URL tip
Some clients ask for a Base URL instead of a full endpoint. Start with https://gpt-agent.cc/v1； and use the site root only when the client expects it: https://gpt-agent.cc。
