List single NEL reports

Report an issue

The reports of POST /analytics/nel one by one, newest first.

One row per report as stored: when and where the request failed, how, the page it was sent from, the visitor and the edge labels. The rows are not weighted, and failure_sampling_rate says how many failures each one stands for. The filters are those of the aggregate route.

Cursor paginated over (timestamp, id), with no total. visitor_id is absent where the report carries no stitch.

Authorization

bearerAuth
headerAuthorizationBearer <token>

API token generated from the fastmon dashboard (Account → API Token) or at organization level (fmo_…, one that outlives its creator). Send as Authorization: Bearer fm_... or paste the full token (including its prefix) into the Authorize dialog.

Path Parameters

Request Body

application/json
  1. body

Request for the single NEL reports, newest first.

time_range*

Time range, on the time the browser saw the error

filters?

The filters of POST /analytics/nel, with its 422 for a filter the table cannot answer

limit?Limit

Max rows per page

Range1 <= value <= 100
Default50
cursor?|

Opaque resume point from meta.next_cursor of the previous page. It carries the last row's timestamp and id, so two reports of the same millisecond page without a gap or a repeat.

Response Body

Successful Response

application/json
  1. response
data*array<>
meta*

Meta for ClickHouse-backed cursor-paginated lists.

total is intentionally absent: COUNT(*) over beacon tables is too expensive. Clients rely on has_more + next_cursor instead.
