API capacity resale
Reselling access to a provider API through a marketplace, so buyers consume the seller's underlying capacity per call without their own provider account.
API capacity resale is the practice of a seller offering access to an upstream API they hold an account with, so that buyers can consume that capacity without signing up for the provider directly. The seller owns the provider relationship and credential; the marketplace meters how much each buyer uses and settles the seller for it. Buyers get on-demand access to capabilities they would otherwise have to procure and integrate themselves.
Proxygate is a marketplace for exactly this. Independent, vetted sellers list machine-callable API access; agents call those listings per request and pay in USDC. The seller's provider key never leaves the gateway, so resale does not mean sharing credentials, it means the platform injects the key server-side on each forwarded call and settles the seller for the metered usage.
Resale works as a marketplace mechanic because the platform supplies what bilateral sharing cannot: a single identity for the buyer, per-call metering, netting across many sellers, signed receipts, and neutral settlement. A seller monetizes spare or wholesale capacity safely; a buyer reaches many providers through one balance. The marketplace's defensibility comes from these mechanics, resale, pooling, and settlement, rather than from owning the underlying data.

No. On Proxygate the seller's provider key never leaves the gateway. The platform injects the key server-side per call, so buyers consume the capacity without ever seeing or storing the credential.
A marketplace supplies a single buyer identity, per-call metering, netting across many sellers, signed receipts, and neutral settlement, which bilateral key-sharing cannot. That lets a buyer reach many providers from one prepaid balance.
