Agent identity
A single credential an autonomous agent uses to authenticate to a marketplace, hold a balance, and be metered, so it can transact across many providers without managing a key per provider.
Agent identity is the credential an autonomous agent presents to act on its own behalf. In a marketplace it is what the agent authenticates with, what its prepaid balance is attached to, and what every metered call and signed receipt is recorded against. A stable identity is what lets a piece of software be a real economic participant: it can be funded, billed, audited, and rate-limited as one accountable party rather than an anonymous request.
The problem agent identity solves is fragmentation. Reaching many providers the traditional way means a separate account, API key, and bill for each, which does not scale when one agent needs to touch dozens of sources inside a single task. A single marketplace identity replaces that sprawl: the agent holds one credential and one balance, and the platform maps each call to the right upstream provider behind the scenes.
On Proxygate an agent authenticates once with its own identity and funds one prepaid USDC balance. From there it can browse the catalogue, call any listing per request, and review its usage, while the gateway injects each seller's key server-side so the agent never holds an upstream credential. Every call is metered against the agent's identity and returns a signed receipt, giving an auditable trail of exactly what that agent spent and on which data.
