+### `admin/upload/inspect`
+
+Get information about a content CID. This does not return the actual data identified by the CID, just metadata our
+system tracks, e.g. the spaces the content identified by a given CID has been uploaded to and the dates the uploads happened.
+
+#### inputs
+
+`root: CID`
+
+#### returns
+
+The `uploads` property will be a list of spaces the given root CID's content has been uploaded to, along
+with the date it was uploaded.
+
+```typescript
+{
+  uploads: Array<{space: SpaceDID, insertedAt: Date}>
+}
+```
+
+### `admin/store/inspect`
+
+Get information about a shard (i.e., a CAR that contains part of an upload) CID. This
+does not return the actual data identified by the CID, just metadata our system tracks,
+e.g. the spaces the CAR identified by a given CID has been stored in and the date it was stored.
+
+#### inputs
+
+`link: CID`
+
+#### returns
+
+The `stores` property will be a list of spaces the specified shard was stored in, along with the date on
+which it was stored.
+
+```typescript
+{
+  stores: Array<{space: SpaceDID, insertedAt: Date}>
+}
+```
