How this service works

Schedule a signed webhook to wake an AI agent later: ISHOB POSTs your JSON payload to your https callback at deliver_at or after delay_seconds (60 s to 30 days ahead), retrying failed deliveries (1, 5, 15, 30, 60 min). Each delivery carries X-ISHOB-Signature (HMAC-SHA256 with the signing_secret returned once). Free status: GET /v1/alarm/{id}; free cancel: POST /v1/alarm/{id}/cancel. Charged only when the alarm is accepted.

Output

Returns a JSON object with alarm_id (unique identifier), status ('scheduled'), scheduled_for (ISO-8601 timestamp of planned delivery), status_url (path to check alarm status for free), and signing_secret (HMAC-SHA256 secret for verifying incoming webhook authenticity — shown only once).

Example use cases

Delayed agent wakeup after task

“Set an alarm to wake me up in 10 minutes by POSTing this JSON — {"task":"summarize_emails","run":true} — to https://myagent.example.com/resume, with 3 retries if it fails.”

Scheduled reminder at exact time

“Schedule a signed webhook to hit https://crm.example.com/follow-up at 2026-11-01T09:00:00Z with payload {"contact_id":"c_123","action":"send_reminder"} and allow up to 5 retries.”

Time-boxed workflow step trigger

“I need you to fire a callback to https://pipeline.example.com/next-step in exactly 3600 seconds carrying the payload {"pipeline_id":"p_99","step":"validate"}, with 2 retry attempts if the first delivery fails.”

Endpoint

When to prefer

Choose this endpoint when an AI agent or automation needs to defer execution or re-trigger itself after a specific delay or at a precise future time, especially when reliable signed delivery and automatic retry logic are required. Ideal for agentic workflows where the agent must sleep, for scheduling reminders, or for orchestrating multi-step pipelines with time gaps — without running your own cron infrastructure.

Side effects

callback_url is not a valid public HTTPS URL — request rejected
deliver_at and delay_seconds both omitted or both provided — ambiguous scheduling
delay_seconds outside 60–2592000 range — validation error
payload exceeds 8192 bytes — rejected
All retries exhausted if callback endpoint returns non-2xx repeatedly
Invalid ISO-8601 or Unix timestamp in deliver_at — parse error
