Can I subscribe to incremental updates instead of refetching full collections?

Yes. GET /buckets/{bucket_id}/collections/{collection_id}/changeset takes _expected and _since cursors and returns only the records that have changed since the last sync, which is how Firefox itself stays current without redownloading collections.

What are the rate limits for Remote Settings PROD?

Remote Settings is fronted by a CDN and tuned to serve every Firefox client globally, so realistic developer use is rarely throttled, but Mozilla can rate-limit abusive callers. Use the changeset endpoint with cursors and the /batch endpoint to keep request volume low.

How do I monitor a specific collection through Jentic?

Search Jentic for 'fetch mozilla remote settings collection', load the changeset schema, and execute GET /buckets/{bucket_id}/collections/{collection_id}/changeset on a schedule. The agent stores the latest timestamp and passes it as _since on the next call.

Is Remote Settings PROD free?

Yes. Mozilla operates Remote Settings as public infrastructure for Firefox clients and any developer can read the published collections at no cost.

Can I write to Remote Settings via this API?

No. The production endpoint exposes only read operations to the public. Writes happen on Mozilla's internal authoring servers and are reviewed before being signed and published to this read-only surface.

Can I limit what my agent is allowed to do with the Remote Settings API?

Yes. Because you run Jentic One yourself, your own rules decide which Remote Settings operations and buckets the agent may touch. Remote Settings puts the bucket id in the URL path, so you can pin the agent to a single bucket such as main or security-state and let it read only that bucket's collections, records, and changesets. You also choose the exact operations it may call, so it stays on the public read-only feed and cannot reach any authoring or admin surface.
