One API key for frontier models, 1,000+ AI tools, and one invoice
Point your existing SDK at Flatkey's router URL and select models by ID instead of managing a credential per provider.
Frontier chat models and 1,000+ pay-per-call tools share one auth layer, one balance, and one invoice.
Issue scoped keys per agent or environment, capped by spend and restricted to approved models and tools.
Requests route across five channel classes; when one degrades the router reroutes, backed by a 99.5% SLA document.
Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
