POSThttps://your-instance.com/v1beta/models/{model}:generateContent

Gemini's own request format, passed through. The streaming variant is :streamGenerateContent, and both take the same body.

Authentication

Three credential styles are accepted here: an x-goog-api-key header, a normal bearer token, or a key query parameter. Prefer one of the headers — a key in the URL tends to end up in proxy logs and browser history.
