Weilos
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.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
Weilos is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Weilos scores 5.7/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

Weilos is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
