Event APIs

The Event API pushes platform events — alerts firing/resolving, incidents opening, ArcIn root-cause findings — to your systems in real time, so you react to change instead of polling for it.

Streaming events#

Subscribe over Server-Sent Events or a webhook. SSE is ideal for a live consumer:

curl -N -H "Authorization: Bearer $ARC_TOKEN" \
     https://applicare.yourco.com/api/v1/events/stream?types=alert,incident

Event shape#

{
  "type": "alert.fired",
  "severity": "critical",
  "entity": "checkout-api",
  "tags": { "env": "prod", "team": "payments" },
  "root_cause": { "cause": "deploy v412", "confidence": 0.91 },
  "ts": "2026-06-01T14:22:07Z"
}

Delivery guarantees#

Events are delivered at-least-once; each carries a unique id so you can de-duplicate. For push-based delivery to a URL, use Webhooks instead of holding a stream open.
