Schedule HTTP requests to be executed in the future.

⚠️ Experimental Service: This is a free, experimental service provided as-is with no guarantees. Use with caution.

import { delay } from "https://esm.town/v/std/delay/client.ts";

// Delay by 5 minutes
await delay.schedule({
  url: "https://myapp.com/webhook",
  delaySeconds: 300,
});

// Or schedule for a specific time
await delay.schedule({
  url: "https://myapp.com/webhook",
  method: "POST",
  headers: { "Authorization": "Bearer token" },
  body: { orderId: 123 },
  executeAt: "2024-12-25T10:00:00Z",
});

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

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

Schedule a delayed HTTP request.

* Either delaySeconds or executeAt is required (not both)

The TypeScript client provides a convenient wrapper around the API.

import { delay } from "https://esm.town/v/std/delay/client.ts";

Schedule a request with full configuration options.

const result = await delay.schedule({
  url: "https://api.example.com/webhook",
  method: "POST",
  headers: { "X-Custom-Header": "value" },
  body: { data: "payload" },
  delaySeconds: 60,
});

Convenience method to schedule by delay duration.

await delay.delayBy("https://api.example.com/webhook", 300);

// With additional options
await delay.delayBy("https://api.example.com/webhook", 300, {
  method: "PUT",
  body: { updated: true },
});

Convenience method to schedule for a specific time.

await delay.delayUntil("https://api.example.com/webhook", new Date("2024-12-25T10:00:00Z"));

// Or with an ISO string
await delay.delayUntil("https://api.example.com/webhook", "2024-12-25T10:00:00Z");
