FAQ

Understand the evidence.
Put it to work.

What is API abuse?

API abuse is the repeated or automated use of an API outside its intended limits, such as farming free credits or exhausting a product quota. This page focuses on abuse tied to visitors and accounts in a web product.

How does ShieldLabs help prevent API abuse?

ShieldLabs detects browser bots, masked visits and multi-accounting around signup and access. Use those results with your own API entitlement and usage records before granting more quota.

Does ShieldLabs inspect every server-to-server API request?

No. ShieldLabs identifies browser visitors and returns risk results for your web journey. Your API gateway and application enforce endpoint limits, authentication and request-level controls.

Can one user restart an API free tier with a new email?

Multi-accounting detection can link accounts registered under different email addresses. Your product supplies the account and quota records needed to enforce free-tier eligibility.
