Python API integration with GetAPI.ONE: OpenAI SDK and Responses

Install the official OpenAI Python SDK, point it at the ONE base URL, make a controlled Responses request, and verify the result without putting credentials in source code.

Start here

This Python example sends a text request through the Responses endpoint. You need a GetAPI.ONE API key and a model that explicitly supports this endpoint. Keep the key in your process environment; the example does not apply to every image or video model.

Prepare the project and credential

Python 3.10 or newer and a virtual environment.
An enabled GetAPI.ONE API key with a deliberate expiry and quota.
A model ID copied from the current catalog whose declared endpoint is Responses.

powershell

python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade openai

Configure and send the request

Set GETAPI_ONE_API_KEY in the process environment; do not paste the key into the file.
Create the client with https://www.getapi.one/v1 as base_url.
Replace the conspicuous model placeholder with an exact current catalog ID that declares Responses.
Run the script only when you accept that the request may be billed.
The first verification disables SDK retries. Add only bounded, observable retries after deciding which operations are safe to repeat.

python main.py

import os
from openai import OpenAI

api_key = os.environ.get("GETAPI_ONE_API_KEY")
if not api_key:
    raise RuntimeError("Set GETAPI_ONE_API_KEY before running this program")

with OpenAI(
    api_key=api_key,
    base_url="https://www.getapi.one/v1",
    timeout=30.0,
    max_retries=0,
) as client:
    response = client.responses.create(
        model="<MODEL_ID_FROM_CURRENT_CATALOG>",
        input="Reply with one short readiness check.",
    )
    print(response.output_text)

Understand the contract

Field	Required value
base_url	https://www.getapi.one/v1
api_key	GETAPI_ONE_API_KEY from the server environment
model	Exact ID from the current catalog
method	client.responses.create

Verify the expected result

The process exits without an authentication or endpoint error.
response.output_text contains the requested short answer.
The GetAPI.ONE console shows a matching request or usage record for the key.

Fix common errors

Symptom	Check
401 or authentication error	Re-copy the ONE key, confirm it is enabled, and verify the environment variable belongs to this process.
404	Keep exactly one /v1 in base_url and use the Responses method only for a model that declares that endpoint.
Model unavailable or incompatible	Copy the exact ID again from the current catalog; do not infer aliases.

Keep the integration safe

Run the SDK only in trusted server or local tooling code, never in browser JavaScript.
Exclude .env files from version control and rotate a key immediately if it is exposed.
Use separate bounded keys for development and production.
