Team-scoped (every teammate's active facts, across all hubs), sorted by category then newest first, with no pagination. `confidence` runs 0-1, `channels` names the communication types the fact was learned from, `sourceCount` how many communications back it, `asOf` the most recent of those, and `isOwn` whether the fact came from your own communications. Correct a fact with PATCH or retire it with DELETE; either takes effect in the hubs on the next daily run. Errors: - `429` `RATE_LIMITED` — More than 30 knowledge-hub/campaign requests in a minute (or 1000 in a day). Knowledge hubs share the campaigns bucket. Requires one of the following token scopes: campaigns. ## OpenAPI ````yaml /openapi.json get /business/knowledge-hubs/learned-facts openapi: 3.1.0 info: title: Fuse Business API version: 1.0.0 description: >- External API for lists, campaigns, prospect search and contacts.
