Gemini Native API (v1beta)

Subset of Gemini native endpoints supported by ONR.

In addition to OpenAI-style endpoints, ONR supports a subset of Gemini native endpoints:

• POST /v1beta/models/{model}:generateContent
• POST /v1beta/models/{model}:streamGenerateContent (SSE; alt=sse is added if missing)
• GET /v1beta/models

Example (force provider via header):

curl -sS http://127.0.0.1:3300/v1beta/models/gemini-2.0-flash:generateContent \
  -H "Authorization: Bearer change-me" \
  -H "x-onr-provider: gemini" \
  -H "Content-Type: application/json" \
  -d '{"contents":[{"role":"user","parts":[{"text":"hello"}]}]}'
