## Summary

Public data intelligence platform offering 55 tools across nonprofit, security, compliance, patents, domain, government contracting, and regulatory data categories for AI agents.

## Context

281 sites in this index share the category "analytics and observability"; 53 are transactional.

## How we grade

- tier 1 — **Declared**: The site says agents are welcome in its robots.txt. A permission, not a capability.
- tier 2 — **Probe-verified** (this site): We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.
- tier 3 — **Behaviourally verified**: An agent completed the action end to end — booked, bought, submitted — and it worked.
