Integrations: Claude Code, Codex, Cursor and more

With a single Kadraris key, your coding agent, in an editor or a terminal, can write code using Claude, GPT and Gemini, and it can also make video, images and music. Use this page as an index: every tool has a short setup line here and a link to its detailed guide.

Three ways to connect

You can use any of these on its own or several at once.

• A different base URL. The tool sends its model requests to Kadraris rather than straight to the vendor. For Claude Code that is the Anthropic-style address https://kadraris.com; for everything else it is the OpenAI-style https://kadraris.com/v1.
• MCP server at https://kadraris.com/mcp. The agent gains tools for listing models, estimating cost, generating video and images, and reading the balance. This is the route to media from inside an agent. See MCP server.
• AGENTS.md. A text file in your repository that documents the Kadraris API, so any agent working there knows how to call it. See AGENTS.md file.

Before anything else: a key

1. Create an account and add funds (from $10, paid by card).
2. In the dashboard, open API keys.
3. Name the key after the tool, for example claude-code, and set a Monthly limit. Somewhere around $10-20 is enough to begin with.
4. Press Create key and copy the sk-kd-... value immediately, as it will not be shown again.

Give every tool its own key. If one of them misbehaves, you revoke that key and the others carry on.

Setup per tool

Where you see a dash, either the tool lacks that option or I have not checked its configuration against the vendor's own documentation.

Tools not listed here

Most apps have a setting labelled along the lines of "OpenAI-compatible", "custom endpoint" or "base URL". Enter these values:

If the app can connect to a remote MCP server (Streamable HTTP transport), use https://kadraris.com/mcp with the header Authorization: Bearer sk-kd-....

Why Codex cannot run on Kadraris models

Kadraris accepts chat in two formats: POST /v1/chat/completions (OpenAI) and POST /v1/messages (Anthropic). It does not implement /v1/responses. Codex CLI currently only allows wire_api = "responses" for a custom model provider, which rules out using a Kadraris model as the model Codex thinks with. MCP still works, so Codex can generate video and images, look up prices and query other models through the chat tool. Details in Codex CLI with Kadraris.

Quick key check

Confirm the key is valid before you configure anything.

macOS and Linux:

curl https://kadraris.com/v1/balance -H "Authorization: Bearer sk-kd-..."

Windows PowerShell:

Invoke-RestMethod -Uri "https://kadraris.com/v1/balance" -Headers @{ Authorization = "Bearer sk-kd-..." }

If it works, you get your balance back, something like {"balance":"12.40","available":"12.40","currency":"USD",...}. A 401 tells you the key is wrong or has been revoked.
