Overview

Acts as a self-hosted, non-custodial gateway that maps your existing API into agent-to-agent discovery, invocation, and payment flows. Implements agent-commerce and payments primitives so agents can discover services, request access, and settle micropayments without custodial infrastructure. Notable features include support for ACP/AP2-style mandates and EIP-3009-style off-chain payment flows for agent-enabled micropayments. This aligns with the Agent-to-Agent Protocol (A2A) standards to enable seamless cross-agent interactions.

Key Benefits

As agents transact and delegate work to third-party APIs, having a non-custodial bridge for discovery and payments reduces trust friction and centralization. Until now, enabling agents to pay and call third-party services required bespoke integrations or custodial payment rails; a protocol gateway standardizes those interactions and emits clear signals (service availability, payment receipts, mandates) that can feed reputation and evaluation systems. That transparency makes it easier to link financial interactions to agent track records and multi-agent trust metrics. See how this relates to Capability Discovery to understand how agents locate compatible services and protocols.

Ideal For

Developers building agent ecosystems who need a protocol-level, non-custodial bridge for agent discovery, access control, and micropayments. This gateway supports standard patterns like the Agent Protocol to ensure interoperable integrations and can also benefit from Agent Communication to align messaging with trust and reputation systems.

Real-World Examples

Expose an existing API to autonomous agents with non-custodial payment and mandate flows
Enable agents to discover and securely invoke paid services while preserving billing transparency
Emit payment and access events that feed agent reputation and evaluation pipelines
