Overview

AI/ML API is a multi-model AI gateway that gives developers access to 400-plus AI models through one API, removing the need to manage separate keys, billing accounts, and SDKs for each model provider. The company was founded in 2021 and has grown to around 50,000 developers in its community.

The service works as a transparent proxy layer compatible with the OpenAI SDK: developers swap in an AI/ML API key and change their base URL, and existing OpenAI-formatted code continues to work while routing to models from OpenAI, Anthropic, Google, Meta, DeepSeek, and Alibaba, among others. Billing runs on a shared credit system (2,000,000 credits per dollar) rather than separate accounts per model provider.

AI/ML API suits developers and teams building AI features who want model flexibility without rebuilding integration code for each provider they test. There's no monthly subscription; new users get free starter tokens up to 10M, after which usage is pay-as-you-go with a $20 minimum prepaid balance.
