Complete API intelligence in six layers.

Each layer is independently useful. Together they give you visibility no other tool provides.

1

The CLI Scanner

Start with a coverage report in one command.

The EndpointLens CLI scanner parses your OpenAPI specification and recursively scans your frontend source directory for references to every endpoint. It uses three-pass pattern matching across React, Next.js, Vue, Angular, Svelte, and any framework that makes HTTP calls as strings.

The Interceptor SDKs

One import. Zero latency. Live traffic in seconds.

Install the EndpointLens interceptor SDK for your backend framework. It captures every request asynchronously after the response has been sent. Your users never wait for EndpointLens. The SDK adds under one millisecond of overhead on average.

The Unified Dashboard

Coverage and traffic in one view.

The dashboard fuses your static coverage data with live traffic data. For every endpoint you see its coverage status, file references, call count, average response time, error rate, and last seen timestamp.

Intelligence Signals & API Surface Score

Four signals. One score. Complete clarity.

Dead Wired. Orphaned. Redundant. Healthy. Four signals computed from the combination of your static coverage and live traffic. All four combine into the API Surface Score — a single number from 0 to 100.

Notifications & Alerts

Get alerted the moment something changes.

The Notifications Worker evaluates all active projects every 5 minutes. When a signal fires it dispatches through every configured channel simultaneously.
