API aggregator
A service that provides access to many separate APIs through a single account and integration, so a consumer does not sign up and integrate with each provider individually.
An API aggregator sits between a consumer and many underlying API providers and offers them through one point of access. Instead of holding a separate account, key, and bill with each provider, the consumer integrates with the aggregator once and reaches every connected API through it. The aggregator handles the fan-out to providers, and often the billing, so the cost of using one more API drops to almost nothing.
Aggregators vary in how much they normalise. Some simply route to each provider's native interface while consolidating access and billing; others present a single normalised schema across providers in the same category. The shared benefit is reduced integration and account overhead: one relationship instead of dozens.
Proxygate aggregates API access for agents and adds a payment and trust layer on top. A buyer holds one identity and one prepaid USDC balance and calls any listed API per request, while the platform injects each provider's key server-side and returns a signed receipt for every call. The agent never collects keys from each provider, and settlement nets across all of them into a single balance.
