Gemini API - Access Google Gemini Models via AIsa - AIsa

AIsa gives you access to Google’s Gemini models with one AIsa API key. Gemini models use the Gemini-compatible POST /v1beta/models/{model}:generateContent endpoint, so the Google Gen AI SDK works after you change its base URL.

Supported Gemini models

Model ID	Type	Endpoints
`gemini-3.8-flash`	Text	`/v1beta/models/{model}:generateContent`
`gemini-4-argon`	Text	`/v1beta/models/{model}:generateContent`

Current prices for these models are on aisa.one/models.

Quickstart

AIsa reads the key from Authorization: Bearer or x-api-key, not from Google’s x-goog-api-key header, so pass it as an extra header.

from google import genai
from google.genai import types
import os

key = os.environ["AISA_API_KEY"]
client = genai.Client(
    api_key=key,
    http_options=types.HttpOptions(base_url="https://api.aisa.one", headers={"x-api-key": key}),
)

response = client.models.generate_content(model="gemini-3.8-flash", contents="Explain vector databases in three sentences.")
print(response.text)

Request and response fields are in Gemini Generate Content.
