GraniteShares
GraniteShares is an independent exchange-traded fund (ETF) issuer that builds alternative, single-stock and thematic investment products for investors who want differentiated exposure. Its lineup spans 2x leveraged and inverse single-stock ETFs (such as NVDL for NVIDIA and TSLR for Tesla), YieldBOOST options-income ETFs, autocallable ETFs, physically-backed gold and broad commodity ETFs, and diversified income and equity strategies across U.S. and European markets. GraniteShares publishes no public developer or data API program; this API Evangelist profile catalogs the company's public web surface and the machine-readable discovery documents (OpenID Connect / OAuth 2.0 member authentication for its Umbraco-powered site) that were probed from its domain. It was surfaced as a portfolio company of Bain Capital Ventures.
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 GraniteShares the way a machine reads it — 2 machine-readable artifacts, 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 — GraniteShares scores 14.0/100 (minimal), with a separate agent-readiness read of 14/100 (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 GraniteShares
Each block below is one kind of artifact we hold for GraniteShares. 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 2
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.
