Access is prepaid with usage charged according to the selected model and group. Vouchers start at CNY 5. There is no free tier or free trial. The website is in Chinese. Before choosing a group, users can review the available models and current rates on the official site.

What problem it solves

Developers need a single OpenAI-compatible API base URL for the GPT models available in the current GO, PLUS and PRO groups, with prepaid usage.

Apidog is an all-in-one API development platform that brings designing, testing, mocking and documenting APIs together in a single, collaborative tool. Working with APIs typically involves several different tools — one for design, another for testing, others for mocking and documentation — which fragments the workflow and makes it hard to keep everything in sync. Apidog unifies these into one platform, so teams can manage the entire API lifecycle in one place, keeping design, tests, mocks and docs consistent and reducing the friction of switching between tools.

The platform lets you design APIs (defining endpoints, schemas and specifications), test them by sending requests and validating responses, automatically generate mock servers so frontend and backend teams can work in parallel before an API is fully built, and produce documentation that stays in sync with the API design. By integrating these capabilities, Apidog ensures that your API specification, tests, mocks and documentation all reflect the same source of truth, which improves accuracy and collaboration across teams. It's positioned as a comprehensive alternative to using multiple separate API tools, with collaboration features for teams.

Apidog is used by developers and teams who work with APIs and want a single, cohesive tool to handle the whole API workflow — design, testing, mocking and documentation — rather than juggling several products and fighting to keep them aligned. By unifying these tasks and keeping everything in sync, it streamlines API development and improves collaboration between frontend, backend and QA teams. Its all-in-one approach addresses a real pain point for teams whose API work is currently spread across disconnected tools. As APIs remain central to modern software and teams seek to work more efficiently and consistently, integrated API platforms are increasingly attractive. For developers and teams that want to design, test, mock and document their APIs in one collaborative platform, Apidog offers a capable, comprehensive and genuinely useful solution.
