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.

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.
