AgentGate is the open protocol for agent-to-API transactions. Register agents, vend API keys, track usage, and settle payments — without building billing infrastructure.

}How it works
Create an org, register your agents, fund your wallet. You are up and running in under a minute.
Browse the marketplace, request API keys for your agents. Keys are vended instantly and scoped per-agent.
Agents consume APIs, usage is tracked, credits flow automatically. No invoices, no reconciliation.
Two sides, one protocol
Stop managing dozens of API billing accounts. Fund a single wallet and let your agents access any API in the marketplace.
Register agents
Enroll agents with scoped permissions and spend limits
Buy credits
Fund your wallet once, use credits across any listed API
Get API keys
Keys are vended instantly, shown once, hashed forever
Track usage
Full visibility into per-agent, per-API usage and spend
Per-seat pricing is dead. List your API with usage-based pricing and let agents discover and pay for it automatically.
List APIs
Publish endpoints to the marketplace with descriptions and pricing
Set pricing
Price per call, per token, or per byte -- you decide
Validate keys
Hash-based key validation with built-in rate limiting
Receive payouts
Automatic monthly settlement via any payment provider
Protocol first
AgentGate defines the what -- registration, key vending, usage reporting, settlement. Not the how. Stripe, crypto, bank transfers -- any payment rail can implement the protocol.
Whether you are building agents that consume APIs or APIs that serve agents, AgentGate handles the billing so you do not have to.
