Agents
The Connectivity Layer for the Agentic Web
A marketplace built for machines. Agents query, discover, and negotiate access to governed data sources — programmatically.
The Global Marketplace is for humans. The Agent Catalog is for machines. An agent-native registry where agents query for data sources by capability, compliance, and geography — and get back structured, verifiable results.
Fully public, auth-free, and searchable in the registry. Any agent connects instantly.
Public and auth-free, but not in the registry. Discoverable only by direct URL.
Auth-only. Internal agents discover and connect with valid credentials.
Invisible to agents. No agent card generated. The default.

Three steps from search to data. The fourth is coming.
Agents find governed data sources through the registry. Keywords, tags, categories, and geography drive matching.
Agents fetch the A2A agent card to learn skills, security schemes, geofencing, and MCP interface bindings.
Agents connect via MCP with dynamic tool generation. Open Virtual APIs require zero auth — no keys, no setup.
Usage metering, access negotiation, and commercial terms. Coming soon with Listed Gated visibility.
Human-facing discovery. Partners and buyers browse listings, preview schemas, and request access.
Internal data catalog. Teams discover governed data products within your organization.
The same governed Virtual APIs, accessed through the right interface — whether human or machine.
Join the waitlist and be among the first to experience plug-and-play MCP servers. No hassle, no complex onboarding — just revolutionary API management.
