What teams use BuildAPI for

Keys that only work where you say, checked on every call, with the record to prove it. Here is how that fits different kinds of product.

Issue a key per storefront, locked to its own domain, with its use counted separately and its own per-minute limit if you want one.

Give each customer a scoped key, and suspend, revoke or rotate it without a deploy. Rotation keeps the old value working for a grace window.

Signed, nonce-bound verification you can prove came from us, and a log of every call with the reason for each refusal.

Ship client sites whose keys keep working on the client's domain and stop working if the site is copied elsewhere.

Scan the DNS, email and web setup of domains you own, watch them for regressions, and push findings to your SIEM or issue tracker.

Serve copy, settings and markup from us at runtime, so a copied site comes up empty instead of showing your content.
