The BuyUKeSIM Partner API
Create real, fulfilled UK Number and Travel eSIM orders from your own systems. Same prices as the website, same instant fulfillment - no fake sandbox, no waiting for approval.
List price: UK Number $25 · Travel eSIM from $0.99. Your account gets a partner discount off these prices (set for you, visible in your dashboard). Fund a prepaid balance in crypto and every order is deducted automatically.
Real fulfillment, not a sandbox
Every order created through the API goes through the exact same eSIM/number provisioning as the website checkout.
Server-side pricing you can trust
You never send a price - it's computed server-side from the live catalog, so integrations can't be mispriced.
Prepaid balance, top up in crypto
Fund your balance once, then create orders instantly with no per-order checkout flow.
Key shown once, hashed at rest
Your API key is shown only at creation time - we store only a one-way hash, never the raw key.
