About APIAssert

API monitoring that catches what 200 OK misses

APIAssert was built out of frustration with existing API monitoring tools that only check if your endpoints return a 200 status code.

The Problem

Traditional uptime monitors tell you your API is "up" even when it's returning empty arrays, wrong data, or malformed responses. By the time you notice, your users have already been affected.

Our Solution

APIAssert validates the actual content of your API responses. Check JSON paths, verify headers, validate response times, and catch bugs before your users do.

Built for Developers

We're developers building tools for developers. APIAssert is designed to be simple to set up, powerful when you need it, and priced fairly for teams of all sizes.
