[Getting started](https://support.reloadly.com/what-can-i-build-with-the-reloadly-top-up-api#get-started) ## How the Airtime API works The Airtime API lets your application send a prepaid mobile top-up to virtually any phone number in the world. Behind a single integration, Reloadly handles the operator detection, pricing, and delivery, so you don't need a direct relationship with each carrier. 600+ Mobile operator networks supported worldwide Instant Top-ups delivered to the recipient's phone in real time 1 API A single integration covers operators across every supported country ℹ️ **Two ways to recharge:** a customer can top up their **own** prepaid line, or send a recharge to someone else's number — which is what makes this such a strong fit for remittance and diaspora use cases. ## 12 industries that use mobile recharge Mobile recharge is a perfect complementary, added-value service for these industries: 💳 Fintech Add airtime top-ups as a feature inside banking or wallet apps, giving users another reason to keep funds in-app. 🌍 Remittance Let senders top up a family member's phone abroad alongside or instead of a cash transfer. ✈️ Travelers Help travelers top up a local SIM the moment they land, without hunting for a kiosk. 🏨 Hospitality Hotels and booking platforms can offer airtime as a guest perk or upsell during checkout. 🎁 Loyalty Use mobile recharge as a reward option inside points and loyalty programs. 📡 Telecom resellers / carriers Resellers and MVNOs can extend their own top-up offering to operators they don't have a direct deal with. 📶 WiFi apps Public WiFi and connectivity apps can bundle airtime as part of a paid or rewarded access plan. 🌐 Diaspora / expat apps, blogs & sites Communities serving expats can let members top up phones back home directly from the platform they already use. 🏛️ Government agencies Agencies can distribute mobile credit as part of social programs or emergency assistance. 🛒 Supermarkets / gas stations Add top-ups at checkout, in-app, or at the till as a convenient extra service for shoppers. 📲 Mobile recharge distributors / resellers Build a dedicated top-up business on top of Reloadly's operator network instead of negotiating with carriers one by one. 🏬 Retail shops Brick-and-mortar and online retailers can sell mobile recharge as an additional product line. ## ⚡ Getting started Every integration follows the same basic pattern, regardless of which use case you're building for: - **Authenticate** against the Airtime API using your client credentials. - **Look up operators** for a given country, or auto-detect the operator from the recipient's phone number. - **Send the top-up** with the recipient's number, operator, and amount. - **Confirm delivery** using the transaction response or webhook.
