Kaopu API is an AI-powered API gateway that gives developers one standard interface to many large language and image models. It is built on the open-source New API platform and includes a web console and dashboard.
Instead of managing separate accounts and keys with each model provider, users call a single unified endpoint. The site shows support for chat, responses, Claude and Gemini style protocols, with example requests using curl.
A Model Square page lists the 21 models currently enabled, grouped by provider: OpenAI, Anthropic and Google. Each model shows its input, output and cached token prices, and the page can be filtered by vendor, group, type and tag.
Key features include one-click configuration for supported apps such as Cherry Studio and CC Switch, a documentation link, sign-in and sign-up pages, a user dashboard, and a language and theme toggle.
Pricing: Usage is billed per token, with prices listed per million tokens for each model and a rate multiplier shown for each model group.
It is suited to developers and teams who want to route requests to several AI models through one API and compare model prices in one place.
