One balance · One key · Every model
Fill up a single prepaid balance, get one API key, and call text, image, video, voice and embedding models from every major lab — through one OpenAI-compatible endpoint. No more six dashboards and six bills.
from openai import OpenAI
client = OpenAI(
base_url="https://api.thesourceai.dev/v1",
api_key="src-••••••••••••", # one key
)
# swap the model string — that's the whole migration
reply = client.chat.completions.create(
model="anthropic/claude-…", # or openai/…, google/…
messages=[{"role": "user", "content": "Hello"}],
)
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://api.thesourceai.dev/v1",
apiKey: process.env.SOURCE_KEY, // one key
});
const reply = await client.chat.completions.create({
model: "google/gemini-…", // any model, same call
messages: [{ role: "user", content: "Hello" }],
});

Providers on the launch roadmap
Fill up
Pick any amount from $5 to $10,000. Credits land on your balance instantly and every key on your account draws from it. The bigger the fill-up, the lower the fee — and models from the big labs are billed at their own list price.
Checkout opens at launch. Credits are valid for 12 months.
How it works
Add credits once with a card or bank transfer, or turn on auto-refill so you never hit zero mid-launch.
Create as many keys as you like — one per app, teammate or client — each with its own spending cap.
Point your existing OpenAI SDK at our endpoint and change the model name. We route, fail over and meter every call.
The map
The flagship reasoning and chat models.
Llama, Qwen, DeepSeek, Mistral — routed to the fastest, cheapest healthy host.
Generate visuals and clips from the same key, billed per image or per second.
Text-to-speech, speech-to-text and voice agents.
Search, RAG and recommendations.
Answers with live web citations.
Built for people who ship
If a provider is down or rate-limited, your call moves to the next healthy host automatically.
Hard spending caps per key. A leaked key or a runaway loop can never drain your whole balance.
Set a floor and a refill amount. Your apps stay online without anyone watching a balance.
Fill up once, hand each client a capped sub-key, and get a clean per-client usage report to bill from.
Spend by model, key, app and day. Export to CSV whenever accounting asks.
Already have provider contracts? Plug them in and still get one endpoint, routing and analytics.
Pricing
Models from the big labs cost exactly their list price. Open-weight models run at our posted price, routed to the fastest healthy host. We earn a small fee when you fill up.
$0/month
$29/month

FAQ
Not on the big labs: OpenAI, Anthropic, Google and xAI models are billed at their published list price. Open-weight models (Llama, Qwen, DeepSeek and others) are served by many hosts, so we post our own price for those and route each call to the fastest healthy host. Every price is shown before you call.
Ours. The Source AI holds its own commercial accounts with each provider and pays them directly. You never handle provider keys, and we never share or resell anyone else's account.
Credits are valid for 12 months from purchase. We email you well before anything expires.
We never sell your prompts or train on them. At launch every model will be labelled with its provider's data policy, and you'll be able to restrict a key to providers that don't train on API traffic.
Our refund policy for unused credits will be published before checkout opens, and it will apply to every purchase.
We're onboarding the first private-beta accounts now. Join the list and you'll get your key as soon as your spot opens.
Private beta is opening in waves. Leave your email and we'll send your key when your spot is ready.
