Unified API
A single interface that normalises access to many underlying providers in the same category, so one integration works across all of them.
A unified API is one interface that stands in front of several providers offering similar functionality and presents them through a common schema. A consumer integrates once against the unified shape and can then switch or combine underlying providers without rewriting their integration. The unified API absorbs the per-provider differences in fields, auth, and quirks behind a consistent contract.
The distinction from a plain aggregator is normalisation. An aggregator can consolidate access and billing while still exposing each provider's native interface; a unified API goes further and makes the providers look the same to the caller. That uniformity is most valuable where many providers do roughly the same thing and the consumer wants resilience or choice without integration churn.
Proxygate gives an agent a uniform way to discover, price, pay for, and call any listed API, while preserving each upstream API's own request and response shape through a transparent proxy. The uniform layer is identity, discovery, pricing, payment, and receipts; the data contract of each endpoint stays its own. This keeps integration to a single pattern, call_api with a listing and endpoint, without flattening away what each provider actually returns.

Proxygate unifies identity, discovery, pricing, payment, and receipts, so the buying pattern is the same for every listing. It preserves each upstream API's own request and response shape through a transparent proxy rather than flattening the data contract.
