What to pick in your tool's settings so it runs through Zukko.
You need: a fetch_... key (create one) and a balance from $1 (top up). One key works for both modes.
1The rule
| Provider in the tool | Base URL | Models |
|---|---|---|
| OpenAI / OpenAI Compatible | https://api.zukko.pro/v1 — with /v1 | Any |
| Anthropic | https://api.zukko.pro — without /v1 | Claude |
Get /v1 wrong and every request returns 404. The exception is OpenCode (Anthropic, but with /v1).
