# List project signals

`GET /v1/projects/{projectSlug}/signals`

Returns a cursor-paginated page of signals in the project. Each item includes lifecycle `states` plus time-window stats: `firstSeenAt`, `lastSeenAt`, `occurrences`, `affectedSessionsPercent`, `trend`, and `tags`.

## Path parameters

- `projectSlug` string, required — Project slug (human-readable identifier)

## Query parameters

- `cursor` string — Opaque cursor returned in a previous response's `nextCursor`. Omit on the first page.
- `limit` integer — Page size. Defaults to 50; max 200.
- `query` string — Free-text semantic search across the signals' names and descriptions.
- `lifecycleGroup` 'active' | 'archived' — `"active"` for signals that are neither resolved nor ignored; `"archived"` for resolved or ignored signals. Omit to include both.
- `sortBy` 'lastSeen' | 'occurrences' | 'state' — Sort field. `lastSeen` orders by most recent occurrence; `occurrences` by total count in the time window; `state` by lifecycle priority.
- `sortDirection` 'asc' | 'desc' — Sort direction. Defaults to `desc`.
- `fromIso` string, date-time — Lower bound (inclusive) of the time window. Defaults to ~6 days ago.
- `toIso` string, date-time — Upper bound (inclusive) of the time window. Defaults to now.

## Response `200`

Page of signals

- PaginatedSignals
  - `items` Signal[], required — Page of items, in the requested sort order.
    - `id` string, required — Stable signal identifier.
    - `organizationId` string, required — Organization that owns this signal.
    - `projectId` string, required — Project this signal belongs to.
    - `slug` string, required — URL-safe slug derived from `name`. Unique within the project.
    - `name` string, required — Human-readable name.
    - `description` string, required — Description of the signal.
    - `source` 'annotation' | 'flagger' | 'custom', required — Where the signal originated from.
    - `states` string[], required — Active lifecycle states. A signal may carry multiple states at once (e.g. `escalating` + `new`).
    - `resolvedAt` string, nullable, required — ISO-8601 timestamp at which the signal was resolved, or `null`.
    - `ignoredAt` string, nullable, required — ISO-8601 timestamp at which the signal was ignored, or `null`.
    - `regressedAt` string, nullable, required — ISO-8601 timestamp at which a new occurrence reopened the resolved signal, or `null`.
    - `mutedAt` string, nullable, required — ISO-8601 timestamp at which notifications were muted, or `null`. Muting only silences notifications; incidents still open.
    - `createdAt` string, required — ISO-8601 timestamp of creation.
    - `updatedAt` string, required — ISO-8601 timestamp of the last update.
    - `trend` SignalTrendBucket[], required — Daily occurrence counts over the past 14 days.
      - `bucket` string, required — UTC day bucket (`YYYY-MM-DD`).
      - `count` integer, required — Number of occurrences within the bucket.
    - `tags` string[], required — Tags seen on the signal's occurrences.
    - `firstSeenAt` string, required — ISO-8601 timestamp of the earliest occurrence in the time window.
    - `lastSeenAt` string, required — ISO-8601 timestamp of the latest occurrence in the time window.
    - `occurrences` integer, required — Number of occurrences in the time window.
    - `affectedSessionsPercent` number, required — Fraction of project sessions affected by this signal in the time window, in `[0, 1]`.
  - `nextCursor` string, nullable, required — Opaque cursor for fetching the next page. `null` when there are no more pages. Pass it back in `cursor` to continue.
  - `hasMore` boolean, required — `true` when there is at least one more page after this one.

## Other responses

- `400` — Validation error
- `401` — Unauthorized
- `404` — Not found
