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 \

}'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.
