RouteMux

RouteMux is an AI gateway with one API key and one OpenAI-compatible endpoint, with OpenAI, Anthropic and Vertex protocol support. It routes text, image and video requests, and works with Claude Code, Codex and Cursor. Code examples are given in cURL, Python, JavaScript, Go, Java and PHP.

Pricing is a prepaid balance with no subscription or seats, billed only for successful requests, and unused balance can be withdrawn. Signup gives a trial credit of $0.1 with no card needed and 18 models available at once. The other 40 models unlock after a first top-up of any amount. The site has a console, docs, a model catalog with prices and a status page.
