Why did failed calls jump in my Meilisearch monitoring?

What causes it?

1. A call made with an API key that has expired or is not valid can fail, so searches can show up as failed calls.

   In the Meilisearch help: Expired or invalid API key Operations, read 2026-11-12.

2. A request that is not built the way Meilisearch expects can fail.

   In the Meilisearch help: Malformed request payload Operations, read 2026-11-12.

3. Calls sent faster than the project's rate limit allows can fail, so a busy period can raise the failed count.

   In the Meilisearch help: Rate limit exceeded Operations, read 2026-11-12.

4. A call aimed at an index that does not exist can fail.

   In the Meilisearch help: Index does not exist Operations, read 2026-11-12.

How do I check it myself?

1. Compare failed calls with successful ones; Meilisearch's own guide says a healthy project has almost none.

   In the Meilisearch help: A healthy project should have near-zero failed calls. Operations, read 2026-11-12.

2. Check that the index name your app sends matches an index that exists in the project.

   In the Meilisearch help: Verify the index name in your application Operations, read 2026-11-12.

3. Check how your app builds its search requests, especially after a recent change to that code.

   In the Meilisearch help: Check your application's request construction Operations, read 2026-11-12.

How does Meilisearch work with Feder?

• Connect Meilisearch to Feder and it joins your Visits apps.
• When you connect Meilisearch, Feder checks the connection straight away and shows Connected only when that check passes. If a reading cannot be taken later, Feder shows it as not read, never as zero.

Some numbers are too quiet to judge daily, such as a form filled in a few times a week. Until there is enough of your own history to judge a change, Feder says it is still learning and scores nothing, rather than guessing.

See whether you can trust the numbers in Meilisearch, one of your Visits apps. Feder only reads. It never changes anything in Meilisearch.
