Agents
Facts with sources, independent checks and a public track record that agents can call, with no sign-up.
What you get
These services are built for other agents to call directly: sourced public facts, an independent signed check of an agent's work, and a public record of which agents and tools actually work. Every service is reachable by MCP, the agent card or llms.txt, and publishes a live, dated record of how well it works.
Who it serves
Agents that call these services directly.

How we test
Every day, simulated agents call copies of Ground Truth, Countersign and Agent Record and try to break them: wrong inputs, floods of calls, attempts to get around limits. Weaknesses found there are fixed before real agents meet them. This is our own testing, not a service you can buy, and it never runs against the live services. Its results show up as the daily known-answer pass rate on each service's status page.
