delay.val.run

Schedule HTTP requests to be executed in the future

POST https://delay.val.run

\n\n \n

How It Works

Send a POST request

Include the target URL, timing (delay or specific time), and optional request config

We store and schedule it

Your request is saved and queued for execution at the specified time

Request fires automatically

When the time comes, we send the HTTP request to your target URL

\n\n \n

Quick Start

\n \n

Using the TypeScript Client

import { delay } from \"https://esm.town/v/std/delay/client.ts\";\n\n// Delay by 5 minutes\nawait delay.schedule({\n  url: \"https://myapp.com/webhook\",\n  delaySeconds: 300,\n});\n\n// Or schedule for a specific time\nawait delay.schedule({\n  url: \"https://myapp.com/webhook\",\n  method: \"POST\",\n  headers: { \"Authorization\": \"Bearer token\" },\n  body: { orderId: 123 },\n  executeAt: \"2024-12-25T10:00:00Z\",\n});

\n\n

Using fetch directly

await fetch(\"https://delay.val.run\", {\n  method: \"POST\",\n  headers: { \"Content-Type\": \"application/json\" },\n  body: JSON.stringify({\n    url: \"https://myapp.com/webhook\",\n    delaySeconds: 300,\n  }),\n});

\n\n

Using cURL

curl -X POST https://delay.val.run \\\n  -H \"Content-Type: application/json\" \\\n  -d '{\"url\": \"https://myapp.com/webhook\", \"delaySeconds\": 300}'

\n\n \n

API Reference

Field	Type	Required	Description
`url`	string	Yes	Target URL to send the request to
`method`	string	No	HTTP method (default: \"POST\")
`headers`	object	No	Headers to include in the request
`body`	any	No	Request body (JSON or string)
`delaySeconds`	number	*	Seconds to delay before executing
`executeAt`	string	*	ISO 8601 timestamp to execute at

* Either delaySeconds or executeAt is required (not both)

\n\n

Response

{\n  \"id\": \"550e8400-e29b-41d4-a716-446655440000\",\n  \"scheduledFor\": \"2024-01-15T10:05:00.000Z\",\n  \"status\": \"scheduled\"\n}

Use Cases

⏰ Delayed Webhooks

Send a notification after a cooldown period

📧 Reminder Systems

Trigger follow-up emails at specific times

🔄 Retry Logic

Schedule a retry attempt after a delay

📅 Scheduled Tasks

Execute API calls at future dates

\n\n \n

Limitations

\n ⚡\n ~1 minute precision: Requests are processed every minute, so execution may be up to 60 seconds after the scheduled time\n

\n 🔁\n No retries: If a request fails, it will not be automatically retried\n

\n ❌\n No cancellation: Once scheduled, requests cannot be cancelled\n

\n 🔓\n No authentication: This is an open service with no API keys\n

\n 🧪\n Experimental: This service may change or become unavailable without notice\n
