Each series is one platform on one chain, keyed by platform and chain. One row per trading card and collectibles platform on one blockchain, keyed by platform and chain: name, platform, chain, project slug and network slug. The id is the series key of the tcg-platforms-by-chain timeseries model. | | | | ---------------- | ----------------------------------------------------------------------------------------------------------------- | | Access | Projects\_protocols\_unified | | Tabular model | `tcg-platform-chains`: primary key `id` | | Timeseries model | `tcg-platforms-by-chain`: intervals `1d`, series key `id` (Platform Chain ID), every series available in one call | ## Endpoints One page of rows with per-column filters, sorting and pagination. Every series in one request, or the named ones. One series over a time window, keyed by its Platform Chain ID. ## Metrics 21 metrics. Use the `Field` value in `selections`; every point starts with the timestamp and continues in this order. | Field | Name | Type | Unit | Description | | ---------------------- | --------------------------- | ------- | ---- | ----------------------------------------------- | | `grossRevenueUSD` | Gross Revenue (USD) | float64 | | Gross platform revenue in USD. | | `netRevenueUSD` | Net Revenue (USD) | float64 | | Net platform revenue in USD. | | `miscRevenueUSD` | Misc Revenue (USD) | float64 | | Miscellaneous revenue in USD. | | `buybackExpenseUSD` | Buyback Expense (USD) | float64 | | Card buyback expense in USD. | | `referralExpenseUSD` | Referral Expense (USD) | float64 | | Referral expense in USD. | | `gmvUSD` | GMV (USD) | float64 | | Gross merchandise value in USD. | | `volumeInclBuybackUSD` | Volume incl.
