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.
One OpenAI-compatible API for 200+ AI models
RouterBase is a drop-in replacement for the OpenAI SDK: change the base URL and route to 200+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, and xAI.
Auto-select the best provider per request by price, latency, or availability, and fall back to another provider in milliseconds when one fails.
Pay against a single balance and get one invoice across every provider instead of juggling a dozen accounts.
Track spend by model, API key, or project, export to CSV, or query via the API, and set per-key monthly spend caps.
