Infrastructure primitives as APIs

Functions, queues, schedulers, cron, key-value and object storage. Pay per use. No servers to run.

Functions KV Object Storage Queue Scheduler Cron

Compose primitives

JavaScript

// Upload file → Store metadata → Enqueue job → Function processes

// 1. Get upload URL from Storage
const { uploadUrl } = await fetch('/v1/storage/upload-url', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer API_KEY' },
  body: JSON.stringify({ key: 'uploads/report.pdf' })
}).then(r => r.json());

// 2. Store metadata in KV
await fetch('/v1/kv/file:report.pdf', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer API_KEY' },
  body: JSON.stringify({ value: { uploaded: Date.now() } })
});

// 3. Enqueue processing job → triggers Function
await fetch('/v1/queue', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer API_KEY' },
  body: JSON.stringify({
    webhook: 'https://fn.rocketstack.dev/fn_process',
    payload: { file: 'report.pdf' }
  })
});

// 4. Schedule nightly sync via Cron
await fetch('/v1/cron', {
  method: 'POST',
  headers: { 'Authorization': 'Bearer API_KEY' },
  body: JSON.stringify({
    expression: '0 2 * * *',
    webhook: 'https://fn.rocketstack.dev/fn_sync'
  })
});

Compose Primitives highlighted: common flow

Primitives that work together

Queues trigger functions. Cron schedules jobs. KV stores state. Compose what you need — no glue code required.

Compose primitives:Build workflows without managing infra.
Reliable by default:Retries, timeouts, idempotency, audit trails.
Any stack:REST + SDKs generated from OpenAPI.

Start with a single API key.

The APIs

Build with powerful primitives

Functions, queues, schedulers, cron, storage — no infrastructure to run.

Functions API

# Deploy functions from an MCP-enabled client.

# Deploy a function via MCP
mcp.call("rocketstack.functions.deploy", {
  "name": "stripe-webhook",
  "runtime": "nodejs",
  "entry": "index.ts",
  "bundlePath": "./dist.zip",
  "triggers": [{ "type": "http" }]
})

# Get the deployed function
mcp.call("rocketstack.functions.get", { "id": "fn_123" })
# → { "id": "fn_123", "url": "https://fn.rocketstack.dev/fn_123", ... }

# List all functions
mcp.call("rocketstack.functions.list", {})

# Invoke a function
mcp.call("rocketstack.functions.invoke", {
  "id": "fn_123",
  "payload": { "event": "payment.success" }
})
