For agencies and tools

API & resellers

Order programmatically, report under your own brand, and pay less per link than the public rate card.

The API in one request

A single POST creates an order. You get an order ID back immediately, and a webhook when the build finishes with the same rows you would see in the dashboard CSV. Keys are issued from your account settings; the sandbox key is free and returns synthetic reports.

curl -X POST https://api.cloudstacking.io/v1/orders \
  -H "Authorization: Bearer sk_live_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "quantity": 50,
    "targets": [
      { "url": "https://example.com/shoes",
        "anchor": "best trail running shoes" },
      { "url": "https://example.com/",
        "anchor": "Example" }
    ],
    "webhook_url": "https://yourapp.com/hooks/cloudstacking"
  }'

REST + JSON

Four endpoints: create order, read order, list orders, list providers.

Webhooks

Signed callbacks on build start, build complete and day-14 index recheck.

Rate limits

60 requests a minute per key, 500 orders a day. Higher on request.

Reseller programme

Built for agencies who already sell link building and want the fulfilment handled quietly. The qualifying threshold is 200 links a month, or a documented pipeline that reaches it within a quarter.

  • Rate card below the public $3 tier, fixed for 12 months
  • White-label CSV reports with your logo and no Cloud Stacking branding
  • Sub-accounts so each of your clients has an isolated order history
  • Invoiced monthly in arrears once volume history is established
  • Named contact who answers within the working day
  • Early access to new provider pools before they go public
