The id is the platform's Blockworks Research slug and can be passed straight back as the platformIdentifier of the platform time series route; each chain carries the series key of its platform-chain pair, which is the id the time series endpoints return. projectSlug and networkSlug are the Messari mappings and are null where the platform or chain maps to no Messari record. Paging is over platforms, so a multi-chain platform is never split across two pages. Sourced from Blockworks Research. ## OpenAPI ````yaml GET /metrics/v2/protocols/tcg 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/tcg: get: tags: - metrics/protocols/tcg summary: List TCG Platforms description: >- Returns one row per Blockworks Research trading-card and collectibles platform, each with the chains it runs on.
