Gemini Native Format

Call Gemini models using a Gemini-style request body when your integration expects Google-native semantics.

Endpoint

POST https://123api.co/v1beta/models/{model}:generateContent

Example


curl --request POST \
  --url 'https://123api.co/v1beta/models/gemini-2.0-flash:generateContent' \
  --header 'Authorization: Bearer <token>' \
  --header 'Content-Type: application/json' \
  --data '{
    "contents": [
      {
        "parts": [
          { "text": "Write a two-sentence product introduction." }
        ]
      }
    ]
  }'

Use this format only if your upstream client or tooling expects Gemini-native requests. Otherwise, the general chat endpoint is easier to standardize.
