Coupon API: frequently asked questions

What is the Coupon API?

The coupon API is a unified REST endpoint that aggregates verified discount codes and store cashback percentages across verified retail shopping networks in real time.

Which sources and retailers are supported?

Our API aggregates data from verified global shopping networks and retailer engines, covering tens of thousands of merchants across fashion, electronics, travel, and beauty.

How does coupon ranking and success count work?

Every coupon returned includes a rank score and a success_count showing how many shoppers recently saved money with that code, allowing you to test winning codes first.

Can I use this for Chrome extensions without user sign-in?

Yes. Extension clients can connect to /api/ext/v1/coupons with origin verification, enabling instant guest lookups at checkout without requiring user authentication.

Yes. When cashback programs are active for a store, the API provides the minimum and maximum cashback percentages alongside coupon codes.

How fresh is the coupon data?

Store results are cached in fast Redis memory for 2 hours to provide sub-10ms response times for repeat checks while keeping coupon codes fresh and active.

How is the coupon API billed?

Billed at 0.5 credits ($0.0005) per request. New developer accounts receive free trial credits upon verification.
