Bold Metrics
Bold Metrics is an AI body data platform for the apparel and fashion industry that uses digital-twin technology to power apparel fit and sizing. From just 4-6 simple body-data inputs it predicts 50+ individual body measurements with tailor-level accuracy, without photos, scanning, or measuring tapes. Its products - Smart Size Chart, Virtual Sizer, Virtual Tailor, Apparel Insights, and the Agentic Sizing Protocol - help brands reduce returns, lift conversion, and increase average order value with personalized size recommendations. The Agentic Sizing Protocol exposes this capability to AI shopping agents while keeping retailer API credentials off the agent and out of any LLM. Bold Metrics has processed 250M+ digital twins and 12B+ body-data points. Backed by Bessemer Venture Partners and Techstars. This profile is maintained in the API Evangelist network; Bold Metrics publishes no public API documentation - integration is gated behind a demo/partner engagement.
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.
API Evangelist profiles Bold Metrics the way a machine reads it — 1 machine-readable artifact, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
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 — Bold Metrics scores 10.8/100 (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.

How we profile Bold Metrics
Each block below is one kind of artifact we hold for Bold Metrics. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
Security Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
