Supported providers
Add provider keys under Settings → API keys → Provider keys (BYOK). Each key is validated with one tiny live model call before it’s saved — so a typo’d key, a key for the wrong provider, or a key with no credit fails immediately rather than at your customer’s first message.
Launch providers
Section titled “Launch providers”Zapito supports exactly three providers:
| Provider | Key looks like | Models in the agent picker |
|---|---|---|
| OpenAI | sk-proj-… | GPT-4o, GPT-4o Mini |
| Anthropic | sk-ant-… | Claude Sonnet, Claude Haiku |
AIza… | Gemini 2.5 Pro, Gemini 2.5 Flash |
You pick the model per AI Agent node, so different bots — or different agents in one flow — can run on different models. New agents default to Claude Haiku, a fast and economical choice for FAQ-style support.
If an agent’s model belongs to a provider you haven’t added a key for, the turn returns an error naming the missing key — you’ll see it in Test chat before your customers ever could.
