# Paginated model-failover events

`GET /agents/{agent_id}/failover-events`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/agents/{agent_id}/failover-events`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-Mnemom-Api-Key`
  - API key in cookie `mnemom_session`

Reads `model_failover_events`: rows recorded at checkpoint-write time whenever the (provider, model) reported on a checkpoint differs from the immediately preceding checkpoint in the same session. Each row is strictly an OBSERVED provider/model change — this API has no visibility into *why* the change happened, so `reason` is always null today. Same owner-scoped read gate as GET /v1/agents/{agent_id}/checkpoints (no new authorization surface).

## Path parameters

- `agent_id` string, required

## Query parameters

- `limit` integer
- `offset` integer
- `from` string, date-time
- `to` string, date-time

## Response `200`

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Forbidden
- `404`: Resource not found
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
