API integration

How to use
the FLUX.2 klein API.

Use the Blade model ID flux-2-klein and keep your API key in your backend environment. Verify account access and supported parameters before connecting production traffic.

Create a Blade API key in the console.
Run pip install openai and set BLADE_API_KEY.
Check the model list below, then use the console’s confirmed inference example for this model.

Read the API reference ↗

python

import os
from openai import OpenAI

client = OpenAI(
    base_url="https://api.models.blade.sh/v1",
    api_key=os.environ["BLADE_API_KEY"],
    timeout=120.0,
)

model_id = "flux-2-klein"
models = client.models.list()
match = next(
    (item for item in models.data
     if item.id == model_id),
    None,
)
if match is None:
    raise RuntimeError("Model not listed for this account")
print(match.model_dump_json(indent=2))

Install openai and set BLADE_API_KEY. This checks the account’s model list; it does not run inference. Copy the confirmed model-specific inference request from the console before integrating.
