+# Reconciliation with Limit Snapshots
+
+A central concept in TROLIE is the Clearinghouse. [Ratings
+Providers](../concepts#ratings-provider) propose ratings, and the [Clearinghouse
+Provider](../concepts#clearinghouse-provider) determines operating limits:
+**ratings in, limits out**.
+
+<img src="../images/reconciliation.excalidraw.png" alt="Reconciliation Diagram" width="600">
+
+Crucially, the limits determined by the Clearinghouse Provider may differ from
+the ratings proposed by any individual Ratings Provider.  In this article we
+will briefly describe the API affordances that support reconciliation of limits
+(produced by the Clearinghouse) with the ratings proposed by the Ratings
+Provider. Our example with focus on real-time ratings, but the basic approach
+applies to forecast ratings as well.
+
+We have discussed [Real-Time Rating Submittal](submitting-realtime-ratings) and
+[Querying in-use Real-Time Limits](in-use-realtime-limits) elsewhere. Here we
+will focus on making use of the provenance information in
+`application/vnd.trolie.realtime-limits-detailed-snapshot.v1+json`. For more
+details on the different response messages available in TROLIE, see the article
+on [Media Types](../articles/media-types#read-requests).
+
+
+#### Request
+```bash
+curl -H "Accept: application/vnd.trolie.realtime-limits-detailed-snapshot.v1+json" \
+  $TROLIE_SERVER_URL/limits/realtime-snapshot?monitoring-set=my-monitoring-set
+```
+
+#### Response
+
+Some headers are elided for clarity, but a successful response will start with:
+
+```http
+HTTP/1.1 200 OK
+Content-Type: application/vnd.trolie.realtime-limits-detailed-snapshot.v1+json
+```
+
+Here's an example of the body of the response:
+
+```json
+{% include_relative examples/realtime-limit-set-detailed.json %}
+```
+
+#### Discussion
+
+The `proposals-considered` array contains the salient details of the ratings
+proposals that were considered.  Note that in this example the continuous,
+"lte", and "ste" limits were determined by UTILITY-A but the "dal" limit was set
+by UTILITY-B.
