Description

RelaySwitch serves as a centralized API gateway for developers, enabling them to access AI models from various providers via a unified endpoint and account. It offers an API that is compatible with OpenAI and accommodates the Anthropic Messages format for Claude models, which allows developers to easily integrate their preferred SDKs and tools by simply updating the base URL and API key. The platform features a diverse catalog that includes chat, image, video, speech, and 3D models, along with detailed model identifiers and token pricing. Billing is conducted using a prepaid USD balance, where separate rates for input and output are provided, and in some cases, utilizing cached input may be more economical. Users can replenish their balance through various accepted payment methods, including credit cards and digital assets, without the need for a monthly subscription. RelaySwitch is specifically designed for developers and teams focused on creating applications and agents utilizing hosted AI models, and it includes extensive API documentation, comprehensive model listings, and setup instructions to facilitate integration with supported SDKs and tools. Additionally, the platform aims to streamline the development process, making it easier for users to leverage advanced AI capabilities in their projects.
