Proof of Usefulness Score
Gaining Momentum

WorldTimeAPI is a widely recognized infrastructure utility in the IoT space, verifying the massive claim of 20 billion responses/month. While it demonstrates exceptional 'Evidence of Traction' through sheer volume and community adoption (ESP8266/Arduino tutorials), the project lacks commercial structure (zero revenue, donation-based) and suffers from reported reliability issues. The submission quality was poor (confusing 'marketcap' data, lazy descriptions), but the verifiable real-world utility of the API sustains a high score comparable to established media brands.
