This is a sibling of the provider listing, not a child of it: an issuer and an underlying asset are two independent cuts of the same data. Latest values are read from the most recent point in the last 30 days; an asset that reported nothing in that window returns nulls and a null asOf. Sourced from Blockworks Research. ## OpenAPI ````yaml GET /metrics/v2/protocols/etfs/assets openapi: 3.0.0 info: description: OpenAPI specification for the entire Messari API title: Messari API - Metrics V2 version: 1.0.0 servers: - description: Messari API url: https://api.messari.io security: [] paths: /metrics/v2/protocols/etfs/assets: get: tags: - metrics/protocols/etfs summary: List ETF Assets description: >- Returns one row per underlying crypto asset held through ETFs, with the asset's latest values split by product type, by region and by strategy.
