Flatkey AI

Flatkey provides a single API gateway that routes requests across multiple AI models and tools. It is built for developers, startups, and AI teams, offering access to numerous providers through one account, balance, and invoice. The service emphasizes unified access and centralized control over usage and costs.

The product describes a model and tool router that lets users switch providers and models without changing their integration. It emphasizes one key, one base URL, and a consistent API experience across providers, with budgets and allowlists to control usage.

Flatkey highlights its architecture with a shared balance and integrated billing, where successful work contributes to the prepaid pool and failed calls incur no charges. It presents a public SLA and aims for operational reliability and governance across providers.

The documentation and pages outline introductory steps and a gateway that enables developer workflows through a single API, SDKs, a CLI, and integration guides, all centered on a unified access model.
