# Get an incident

POST https://api.respan.ai/api/pulses/incidents/{incident_id}/
Content-Type: application/json

Returns one incident with exact counts, the error groups behind it, the providers, models, endpoints and customers it hit, and its latest failed requests. Send an empty body.

Reference: https://respan.ai/docs/apis/errors/get-incident

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.

## Request

### Path parameters

- `incident_id` (string, required) — Incident ID, from List incidents.

## Response

### 200

The incident.

- `incident` (ErrorIncident, required) — The incident, with exact `impact`, `error_count` and `request_count`, and `dominant_fingerprint` set from the top error group.
- `affected` (ErrorIncidentAffected, required)
- `contributors` (ErrorIncidentContributors, required)
- `occurrence_preview` (list of ErrorIncidentOccurrence, required) — The 20 most recent failed requests.
- `data_status` (ErrorIncidentDetailDataStatus, required)
- `links` (ErrorIncidentDetailLinks, required)

## Errors

### 403 Forbidden Error

Forbidden: the API key is missing, invalid or expired; the key doesn't grant `logs:read` (Read access does).

- `detail` (string, required)

### 404 Not Found Error

No incident with this ID in your organization.

- `error` (string, required)

### 429 Too Many Requests Error

Rate limited. This endpoint allows 60 requests per minute per organization.

- `detail` (string, required)

## Types

### ErrorIncident

A window where one environment's error rate for one fault domain rose well above its usual level.

- `id` (string, required) — Incident ID.
- `title` (string, required) — Main error class and environment, in words.
- `environment` (string, required)
- `fault_domain` (enum, required) — Whose fault the failure is, derived from `error_class`: `user` (your requests or your own provider keys), `provider` (the upstream provider), `respan` (Respan's gateway or managed capacity), or `none` (client cancellations).
  - Allowed values: `user`, `respan`, `provider`, `none`
- `started_at` (datetime, required)
- `ended_at` (datetime, required, nullable) — End of the last elevated minute, or `null` while ongoing.
- `duration_seconds` (integer, required) — From `started_at` to `data_through_at`.
- `data_through_at` (datetime, required) — How far the evidence goes: `ended_at` once past; for an ongoing incident, the latest minute that is fully ingested.
- `state` (enum, required)
  - Allowed values: `ongoing`, `past`
- `resolution_reason` (enum, required, nullable) — Why it ended: the rate recovered, requests stopped, or the scope went silent. `null` while ongoing.
  - Allowed values: `recovered`, `no_traffic`, `stale`
- `severity` (enum, required)
  - Allowed values: `low`, `medium`, `high`, `critical`
- `trigger` (enum, required) — `spike` for a sudden jump, `drift` for a sustained smaller rise.
  - Allowed values: `spike`, `drift`
- `peak_error_rate` (double, required) — A fraction from 0 to 1.
- `baseline_error_rate` (double, required) — A fraction from 0 to 1.
- `error_count` (integer, required)
- `request_count` (integer, required)
- `hot_bucket_count` (integer, required) — Minutes that tripped the detector.
- `error_class_breakdown` (map from string to integer, required) — Failed requests per error class.
- `dominant_error_class` (string, required) — Most common error class.
- `dominant_fingerprint` (string, required, nullable) — Error group with the most failures. Usually `null` in List incidents; Get an incident fills it.
- `impact` (ErrorIncidentImpact, required)
- `primary_error` (ErrorIncidentPrimaryError, required)
- `acknowledged_at` (datetime, required, nullable)
- `is_acknowledged` (boolean, required)
- `notes` (string, required) — Team notes. Visible to everyone in the organization.
- `created_at` (datetime, required)
- `updated_at` (datetime, required) — When the detector last evaluated the incident. Acknowledging or editing notes doesn't change it.

- `data_through_at` (datetime, required)
- `reason` (string, required, nullable) — `analytics_unavailable` when `is_partial` is `true`, else `null`.
