Built for the agentic web.

Trust infrastructure
for AI agents

Every service is evaluated against the AgentsOnly certification standard — scored on authentication, MCP support, API quality, and more. So agents know exactly what they can trust.

01Why This Exists

Not for humans.
For agents.

As agentic AI systems proliferate, they need to discover and integrate with services programmatically — not through landing pages and signup flows. AgentsOnly is infrastructure for that layer: a structured, queryable registry that agents can actually use.
