I built Tethyr Cloud for the AWS AIdeas competition - it's a B2B agent federation platform addressing a problem I see emerging: agent discovery is fragmenting across proprietary registries with vendor lock-in.
The architecture has two parts:
open-tethyr (OSS): Agent discovery server implementing the Agent Exchange (AX) protocol draft by Aaron Sempf. Free, decentralized discovery that prevents corporate gatekeeping.
Tethyr Cloud (commercial): Trust layer for B2B commerce - subscriptions, rate limiting, usage metering. Built on the discovery network but doesn't own the data.
Key design decisions:
Peer-to-peer agent execution - payloads never touch Tethyr infrastructure
Stateless JWT validation with <200ms p95 latency
Fire-and-forget usage reporting off the hot path (SQS buffering)
Dual-API boundary (AppSync for dashboard, API Gateway REST for SDK)
