API Aggregator
A service platform that routes requests to multiple large model providers through a single API interface, offering automatic failover, unified billing, and simplified integration. It helps developers avoid the overhead of multi-provider approval processes and per-request payment management.
Timeline (last 90 days)
API aggregators sit between applications and multiple model vendors, maintaining a unified request format, authentication, and billing layer, and routing requests to different backends based on latency, error rate, or cost policies.
API aggregators introduce extra hops, typically adding tens of milliseconds of latency; failover may cause the same prompt to produce inconsistent outputs across different models; and the aggregator itself is a single point of dependency.
API aggregators began to emerge in mid-2025, routing multiple vendors with a single API key to achieve automatic failover.
