OpenCode

Works fully: OpenCode takes any OpenAI-compatible endpoint as a custom provider in its config file.

The kano-proxy CLI does not set up OpenCode. Set it up by hand.

Set it up by hand

Create a key on the Access page.
Put this in ~/.config/opencode/opencode.json for all projects, or in opencode.json at a project root for one project. The model ids are examples; list ids from your own Models page.

json

{
  "$schema": "https://opencode.ai/config.json",
  "provider": {
    "kano": {
      "npm": "@ai-sdk/openai-compatible",
      "name": "Kano Proxy",
      "options": {
        "baseURL": "https://<your-domain>/openai/v1",
        "apiKey": "{env:KANO_PROXY_API_KEY}"
      },
      "models": {
        "claude-code/claude-opus-5": { "name": "Claude Opus 5" },
        "codex/gpt-5.6-sol": { "name": "GPT-5.6-Sol" }
      }
    }
  },
  "model": "kano/claude-code/claude-opus-5"
}

Export the key in the shell you start OpenCode from:

macOS / LinuxWindows

bash

export KANO_PROXY_API_KEY=<your-api-key>

powershell

$env:KANO_PROXY_API_KEY = "<your-api-key>"

Start opencode.

What each setting does

kano is your name for the provider. Model references are <provider name>/<model key>, so the slash inside claude-code/claude-opus-5 is fine.
models lists the ids you want in the picker. The display name is free text. Model id rules are in Endpoints and model ids.
{env:VAR} reads an environment variable at startup. A missing variable becomes an empty string with no error, so an auth failure usually means the export did not happen.

Anthropic format instead

OpenCode can also talk to the Anthropic base by loading @ai-sdk/anthropic. That SDK appends /messages, so the base must end in /v1:

json

{
  "provider": {
    "kano-anthropic": {
      "npm": "@ai-sdk/anthropic",
      "name": "Kano Proxy (Anthropic)",
      "options": {
        "baseURL": "https://<your-domain>/anthropic/v1",
        "apiKey": "{env:KANO_PROXY_API_KEY}"
      },
      "models": {
        "claude-code/claude-opus-5": { "name": "Claude Opus 5" }
      }
    }
  }
}

Use a provider name other than anthropic.

Why not the name anthropic

Overriding the built-in anthropic provider makes OpenCode add Anthropic-specific beta headers. The OpenCode docs describe only the OpenAI-compatible custom provider; the Anthropic form is verified from the source and a third-party gateway guide, not from the docs.

Check it

Send a message in OpenCode with one of the listed models. The request appears on the Logs page within seconds. If it fails with an auth error, check that KANO_PROXY_API_KEY is exported in that shell.

Limits

No known limits through the proxy.
