Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

Capabilities

Tools 8

deadmanssnitch_add_tags

WRITE: add one or more tags to a snitch, keeping the existing ones. Returns the snitch's full tag list. POST /v1/snitches/{token}/tags.

Discovered
deadmanssnitch_create_snitch

WRITE: create a new snitch (monitor). Returns it with its check-in URL (https://nosnch.in/<token>), which the job must call on every run; keep it secret. Fails with 402 when the plan's snitch limit is reached. POST /v1/snitches.

Discovered
deadmanssnitch_get_snitch

One snitch with its full details, including the check-in URL (https://nosnch.in/<token>). The check-in URL is a secret: anyone who has it can check in and so silence the alert; share it only where the job runs. GET /v1/snitches/{token}.

Discovered
deadmanssnitch_list_snitches

List the snitches (cron/heartbeat monitors) of the account with status (pending, healthy, failed, errored, paused), interval, alert type, tags and last check-in. Tokens are masked (the token is also the check-in secret); pass the masked token or the name to the other snitch tools. The API has no paging: all snitches come back. Optionally filter by tags (must have all) or status. GET /v1/snitches.

Discovered
deadmanssnitch_pause_snitch

WRITE: pause a snitch, which SILENCES its alerts: a job that stops running goes unnoticed while it is paused. `until` says when alerting resumes: 'healthy' (default: on the next healthy check-in), 'unpaused' (stays paused until deadmanssnitch_unpause_snitch) or a future ISO 8601 time. A snitch that has never checked in (pending) cannot be paused. POST /v1/snitches/{token}/pause.

Discovered
deadmanssnitch_remove_tag

WRITE: remove one tag from a snitch (the snitch itself is untouched). Returns the remaining tags. DELETE /v1/snitches/{token}/tags/{tag}.

Discovered
deadmanssnitch_unpause_snitch

WRITE: resume alerting for a paused snitch (safe on a snitch that is not paused). POST /v1/snitches/{token}/unpause.

Discovered
deadmanssnitch_update_snitch

WRITE: change a snitch. Only the fields you pass change. `tags` REPLACES the whole tag list (use deadmanssnitch_add_tags to add) and `alert_email` replaces the alert recipients (an empty list = all team members). Returns the updated snitch with the token masked. PATCH /v1/snitches/{token}.
