About this data

This page measures how many public API documentation links return 404 errors, indicating obsolete or removed resources. It also tracks the median response time of these links to assess their reliability. The data comes from periodic scans of public API ecosystems, highlighting the fragility of developer-facing documentation. Understanding this decay helps maintain trust in API ecosystems and informs better documentation practices.

Why this isn't published anywhere else

No existing source tracks the specific metric of 'Global Dead-End Public API Documentation Link Ratio' as a live dashboard or recurring dataset. Related tools (e.g., API Graveyard) focus on API deprecation, not documentation link decay.

Uniqueness score 1.00 — assessed against live web search results when this subject was created.
