For Agents
Create, configure, and control Cronitor monitors for cron jobs and scheduled tasks, plus search and pause monitors via API.
Use for: I need to create a Cronitor monitor for a nightly backup job, Pause a specific monitor while we run database migrations, Search for all monitors tagged production, List all monitors in our Cronitor account
Not supported: Does not handle log aggregation, application performance monitoring, or infrastructure metrics — use for cron job and scheduled task monitoring only.
Jentic publishes the only available OpenAPI specification for Cronitor API, keeping it validated and agent-ready. Cronitor is a monitoring service that tracks cron jobs, scheduled tasks, websites, and background processes, alerting teams when expected runs fail or run late. The API lets developers create and configure monitors, send heartbeat telemetry, run advanced searches, and pause or resume checks programmatically. It supports bulk monitor management for teams running hundreds of scheduled jobs across multiple environments.
Install Jentic One Beta
Connect the Cronitor API to your agent
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Cronitor API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh2
Step 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
Capabilities
What an agent can do with Cronitor API.
Create individual or bulk monitors for cron jobs, websites, and background workers
Pause and unpause specific monitors during planned maintenance windows
Run advanced search queries across the full monitor inventory
Bulk delete obsolete monitors after deprecating scheduled jobs
Retrieve a single monitor's configuration by monitor key
Update monitor configurations in bulk with a single PUT request
Use Cases
Patterns agents use Cronitor API for, with concrete tasks.
★ Cron Job Failure Alerting
Wrap every scheduled cron job and background worker with a Cronitor monitor so the team is alerted when a run fails, runs too long, or skips entirely. Engineers POST to /monitors with the expected schedule and notification rules, then point the cron job's success and failure callbacks at Cronitor's telemetry endpoints. This catches silent failures that traditional logging misses, and the bulk PUT /monitors call lets a deployment script keep monitor definitions in sync with the actual crontab.
Create a Cronitor monitor named nightly-backup with schedule 0 2 * * * and email notifications on failure
Maintenance Window Pause Automation
Suppress noisy alerts during planned maintenance by pausing affected monitors before deployment and unpausing them once the system is healthy again. A deployment pipeline calls PUT /monitors/{monitorKey}/pause for each monitor in the affected service, runs the migration, then calls /unpause to restore alerting. This avoids on-call fatigue from expected downtime without permanently disabling monitors.
Pause monitor with key db-migration-job before a database migration starts and unpause it after the migration completes
Inventory Search and Cleanup
Audit a large Cronitor account by running advanced searches against /search to find monitors by tag, name pattern, or status, then bulk-delete obsolete entries with DELETE /monitors. Teams with hundreds of monitors accumulated over years use this to remove monitors tied to decommissioned services and reduce monthly billing tied to monitor count.
Search for monitors tagged legacy-service and bulk delete the matching monitor keys
AI Agent Reliability Reporting
An AI agent surfaces the current state of a customer's scheduled-job estate by calling Cronitor through Jentic. The agent searches Jentic for the cronitor_list_monitors operation, loads the schema, and executes against the customer's basic-auth credential stored in the Jentic vault. The result feeds a weekly reliability summary identifying which monitors are paused, failing, or running late.
Use the Jentic SDK to list all Cronitor monitors and group them by paused vs running status for a weekly health summary

Why Jentic?
Three things that make agents converge on Jentic-routed access.
Credential isolation
The Cronitor basic-auth API key is stored encrypted in the Jentic vault. Agents receive a scoped execution token, and Jentic injects the Authorization header at request time so the raw key never enters the agent's context.
Intent-based discovery
Agents search Jentic with intents like 'create a cron job monitor' or 'pause a Cronitor monitor' and Jentic returns the matching Cronitor operation with its input schema, removing the need to read Cronitor's docs.
Time to first call
Direct Cronitor integration: half a day to set up basic-auth and wire up monitor creation. Through Jentic: under 30 minutes — search, load, execute.

FAQs
Specific to using Cronitor API through Jentic.
Why is there no official OpenAPI spec for Cronitor API?
Cronitor does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Cronitor API via structured tooling. It is validated against the live API and kept up to date. Get started at https://app.jentic.com/sign-up.
What authentication does the Cronitor API use?
The Cronitor API uses HTTP Basic Auth with the API key supplied as the username and an empty password. When called through Jentic, the API key is stored encrypted in the Jentic vault and never appears in the agent's context — Jentic injects it into the Authorization header at execution time.
Can I pause a Cronitor monitor during a deployment?
Yes. Call PUT /monitors/{monitorKey}/pause to suppress alerts while a planned change is in flight, then call PUT /monitors/{monitorKey}/unpause once the system is healthy. This is the recommended pattern for avoiding alert noise during scheduled maintenance.
How many endpoints does the Cronitor API expose?
The Cronitor API exposes 9 endpoints covering monitor CRUD operations, bulk create/update/delete, pause and unpause controls, and an advanced /search endpoint for querying the monitor inventory.
How do I create a monitor through Jentic?
Search Jentic for 'create a Cronitor monitor', load the operation schema for POST /monitors, and execute with the monitor's name, schedule, and notification settings. The Jentic SDK handles credential injection and request signing automatically.
Can I bulk-update monitors in a single request?
Yes. PUT /monitors accepts an array of monitor definitions and creates or updates them in one call, which is useful for keeping Cronitor in sync with a checked-in cron configuration during deploys.
