● The Problem

Developers building integrations discover rate limits only after deploying to production. Documentation is often wrong or vague about exact throttling behavior.

● The Solution

A testing tool that probes API endpoints to map actual rate limit behavior. Reports burst limits, sliding windows, retry-after headers, and generates client-side throttling configs.
