One API to the top AI models, billed the way you can pay
altrouter is an OpenAI-compatible gateway to GPT-5, Claude, Gemini and dozens of other top text and image models through one key and one endpoint.
One gateway to every model
We route requests to upstream model providers and serve them through one OpenAI-compatible interface. We do not build the models ourselves - our job is to make reaching them simple, cheap and available.
Two walls between a developer and a model
The official OpenAI, Anthropic and Google APIs - and aggregators such as OpenRouter - run into two walls.
Foreign card only.
A separate signup and billing with every vendor.
altrouter removes both:
Card, bank transfer or crypto.
One signup - with us.
The same models, below the vendor price.
Instead of five separate subscriptions and billings.
One line of your code changes
You get one API key and change only the base URL - the rest stays OpenAI SDK compatible.
Requests fail over between providers automatically, so one provider going down does not take your service with it.
You top up a balance and requests are charged against it. Spend limits, keys and full request logs live in the dashboard.
A discount off the official price, not a markup
Every model's price is shown on its own page and in the catalog, derived from the provider's official price, with the discount stated outright. We take no markup over official rates - we charge less.
