Gemini v1beta

Gemini v1beta is for Gemini CLI, Gemini SDKs and tools compatible with the Gemini protocol.

Base URL

Common paths:

API Key

Gemini-style requests commonly pass the key as a query parameter:

?key=YOUR_QUOTAAPI_KEY

Some clients also support request headers. Prefer the method documented by your client.

Configuration notes

Item	Notes
Base URL	If the client appends /v1beta, set https://quotarouter.ai
Full prefix	If the client expects a full API prefix, set https://quotarouter.ai/v1beta
Model name	Must match a Gemini model enabled in the console
Key	Use the API Key created in the QuotaAPI console

Troubleshooting

• 404: check whether /v1beta was appended twice.
• 401: the key is invalid or missing.
• 403: the API Key does not have access to a Gemini group.
• model not found: model name is not enabled, misspelled, or unavailable for that group.
