Set up an API provider

An API provider is a service you pay per token, with a key: the Anthropic API, or any service that speaks the OpenAI API.

Anthropic API

  1. Models → Add a provider. Kind: Anthropic API.
  2. API key: your Anthropic key. "Keys are kept in plain text in KOLONİ's local database on this machine." Once saved, the key "is never shown again".
  3. Address: leave it empty for https://api.anthropic.com.
  4. Default model: needed, for example claude-sonnet-5-5.
  5. Workspace ID: "Only needed for a key that is not scoped to a workspace. Copy it from the Anthropic console."
  6. Press Add provider, then Test. For the Anthropic API, Test reads the model's details and spends nothing.

A service that speaks the OpenAI API

  1. Models → Add a provider. Kind: OpenAI-compatible server.
  2. Address: the service's API address, starting with http:// or https://. The field suggests the services KOLONİ knows from its model catalogue; an address that only names a known service is completed to its full API address.
  3. API key: the service's key. The field says what the service calls its key.
  4. Default model: if you leave it empty, KOLONİ uses the first model the server lists.
  5. Press Add provider, then Test. Test sends one small request to see whether the model can use tools, which costs a few tokens on a paid service. It then says "Reachable" and the model, and adds "this model does not take tools" if it cannot use them.

A model that does not take tools can chat, but agents cannot use KOLONİ's tools with it.

After adding

  • At most this many agents at once: 8 by default for a service.
  • On the Models tab, give the models a Tier, and set Agents may use. See Tiers and Agents may use.
  • On the Limits tab, set dollars a day or a month, or mark the key as a plan. See Limits.
  • Prices come from the catalogue unless you set your own. See Usage and budgets.
