# Weilos

**Canonical:** https://apis.io/providers/weilos/  
**APIs profiled:** 0

Weilos was a health and wellness startup surfaced as an a16z portfolio company and added to the API Evangelist network as a stub for enrichment. As of the 2026-07-21 enrichment pass the company no longer operates independently — weilos.com issues a 301 redirect to weightwatchers.com, indicating Weilos has been absorbed into WeightWatchers (WW). No independent developer surface exists — the hosts api.weilos.com, developer.weilos.com, and docs.weilos.com do not resolve in DNS, and there is no public API, OpenAPI specification, SDK, or developer portal to catalog. This profile is retained as an acquired/defunct lead with no API artifacts.
