One OpenAI-compatible API key for 500+ AI models
Replace separate OpenAI, Anthropic and Google credentials with a single key and switch models by changing one line of code.
Route text, reasoning, coding, image, audio and video workloads through one OpenAI-compatible base URL without rewriting your app.
Line-item pricing per model with discounts below official vendor rates, pay-as-you-go with no monthly subscription or minimum spend.
A real-time dashboard tracks spend, latency and call volume so you can set budget alerts and compare models side by side.
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.
