Get started

Ship your first call in 90 seconds.

Three steps. No waitlists, no sales call, no "schedule an integration review". Sign in, change a base URL, call any model.

Sign in with GitHub →API reference For coding agents

STEP 00

One command (optional)

If you'd rather skip everything below, the CLI walks through it. `aig init` prompts for a key, writes it to .env, and scaffolds a working starter file in TypeScript, JavaScript, or Python — whichever your project already uses.

npx aigateway-cli init
# or install globally
npm i -g aigateway-cli && aig init

STEP 01

Sign in + get a key

One click with GitHub or Google. Your first test key lands in your clipboard. No card required.

# .env
AIGATEWAY_API_KEY=sk-aig-...

STEP 02

Install both SDKs, point at our base URL

aigateway-py gives you sub-accounts, evals, replays, jobs, and webhook verify. The OpenAI SDK handles chat/embeddings/images/audio — it's drop-in compatible once you change base_url.

# pip install aigateway-py openai
# aigateway-py: sub-accounts, evals, replays, jobs, webhook verify.
# openai SDK: chat/embeddings/images/audio — drop-in compat per our SDK's own guidance.
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["AIGATEWAY_API_KEY"],
    base_url="https://api.aigateway.sh/v1",
)

resp = client.chat.completions.create(
    model="anthropic/claude-opus-4.7",
    messages=[{"role": "user", "content": "hello"}],
)

STEP 03

Swap any model, any modality

Same shape for text, images, audio, embeddings. Change the slug, nothing else.

# image
client.images.generate(model="black-forest-labs/flux-2-klein-9b", prompt="...")

# stt
client.audio.transcriptions.create(model="deepgram/nova-3", file=open("a.mp3","rb"))

# tts
client.audio.speech.create(model="deepgram/aura-2-en", voice="asteria", input="...")

# embeddings
client.embeddings.create(model="baai/bge-m3", input="hello")
