Where OpenGrants is ahead
- 78,000+ open grants and contracts merged from Grants.gov, all 50 US state portals, municipal programmes and foundations into one search (per opengrants.io/product).
- Their own MCP server and a public API with webhooks on the Developer tier — one of the only other sellers, besides Instrumentl, of an MCP grant-discovery connector.
- A built-in application pipeline — kanban stages, deadline reminders, team notes — alongside discovery, not just a database.
Where we are ahead
- Free eligibility checking with no $9-a-month floor and no card on file, on both sides of the dataset.
- Coverage outside the US: 77 jurisdictions for companies and 25 countries for households — OpenGrants is a US-only database.
- No published rate limit on our free JSON API; OpenGrants caps its Pro tier at 25 requests a day.
What's actually in Unclaimed

- 2,217 household benefits across 25 countries
- A free eligibility check with no sign-up, on both sides
- An MCP server at /mcp for AI assistants, and a static JSON API beside it
- Daily status refresh, so an "Open" badge does not outlive the deadline it describes
