## Summary

OpenHeritage provides public genealogy and cultural heritage records including archives, photos, memorials, cemeteries, sources, and research projects accessible via global search and APIs.

## Context

1009 sites in this index share the category "community and nonprofits"; 137 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.
