Each series is one issuer, keyed by its issuer id. One row per bridged bitcoin issuer, keyed by the issuer's short name: name, the issuer's project slug and project id. The id is the series key of the bridged-bitcoin-by-issuer timeseries model. | | | | - | - | | Access | Stablecoins-dataset | | Tabular model | `bridged-bitcoin-issuers`: primary key `id` | | Timeseries model | `bridged-bitcoin-by-issuer`: intervals `1d`, series key `id` (Issuer ID), series must be named (up to 10 per call) | ## Endpoints > [card] [List Bridged Bitcoin Issuers](https://docs.blockworks.com/api-reference/data-api/bridged-bitcoin/tabular-bridged-bitcoin-issuers.md) > > One page of rows with per-column filters, sorting and pagination. > [card] [Batch Get Bridged Bitcoin Issuer timeseries](https://docs.blockworks.com/api-reference/data-api/bridged-bitcoin/timeseries-bridged-bitcoin-by-issuer.md) > > Up to 10 series in one request, named by Issuer ID in `series`. > [card] [Get Bridged Bitcoin Issuer timeseries](https://docs.blockworks.com/api-reference/data-api/bridged-bitcoin/timeseries-bridged-bitcoin-by-issuer-by-id.md) > > One series over a time window, keyed by its Issuer ID. ## Metrics 36 metrics.
