Cronhost REST API

The Cronhost REST API allows you to programmatically manage scheduled HTTP requests using familiar cron syntax. Build integrations, automate workflows, and manage your schedules through a simple, RESTful interface.

​
Base URL

All API requests should be made to: 
https://cronho.st/api/v1

​
What You Can Do

With the Cronhost API, you can:
  • Create schedules to automatically execute HTTP requests on a cron schedule
  • Manage schedules with full CRUD operations (create, read, update, delete)
  • Control execution by enabling, disabling, or manually triggering schedules
  • Monitor jobs to track execution history, success rates, and error details
  • Query job history with filtering and pagination

​
Quick Example

Here’s a simple example of creating a schedule that checks an API’s health every hour: 
curl -X POST "https://cronho.st/api/v1/schedules" \
  -H "x-api-key: your-api-key" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Hourly Health Check",
    "description": "Check API health every hour",
    "cronExpression": "0 * * * *",
    "timezone": "UTC",
    "endpoint": "https://api.example.com/health",
    "httpMethod": "GET",
    "maxRetries": 3,
    "timeoutSeconds": 30
  }'

Interactive Documentation

This documentation is built from our OpenAPI specification and includes:
  • Live examples you can test directly in the browser
  • Complete request/response schemas with validation
  • Multiple example scenarios for each endpoint
  • Error response examples to help with debugging

​
Core Concepts

​
Schedules

A schedule defines when and how to make HTTP requests. Each schedule includes:
  • Cron expression for timing (e.g., 0 9 * * * for daily at 9 AM)
  • HTTP details like method, endpoint, headers, and body
  • Retry logic with configurable attempts and timeouts
  • Timezone support for accurate scheduling

​
Jobs

A job represents a single execution of a schedule. Jobs track:
  • Execution status (PENDING, RUNNING, SUCCESS, FAILED)
  • HTTP response details including status codes and response bodies
  • Timing information like start time, completion time, and duration
  • Error details for failed executions

​
Getting Started

  1. Get your API key from the Cronhost dashboard
  2. Review authentication in the next section
  3. Explore the endpoints using the interactive documentation below
  4. Try the examples directly in your browser or with curl

​
Rate Limits

The API has the following rate limits:
  • 100 requests per minute per API key
  • 1000 requests per hour per API key
Rate limit headers are included in all responses:
  • X-RateLimit-Limit: Your rate limit ceiling
  • X-RateLimit-Remaining: Number of requests left in current window
  • X-RateLimit-Reset: UTC timestamp when the rate limit resets
