The networkID is the series key of the blockchains timeseries model. ## OpenAPI ````yaml api-reference/data-api/openapi.json GET /query/tabular/blockchains/{networkID} openapi: 3.0.0 info: description: >- The Blockworks Data API is a unified, read-only REST interface to Blockworks' warehouse-modeled crypto dataset, powered by Messari's research and data infrastructure. It serves two kinds of models: tabular models, which return current, filterable, sortable rows for entities such as assets, networks, protocols, exchanges, stablecoins, and ETFs; and timeseries models, which return historical metric series at a chosen granularity for one or many entities. Every endpoint shares the same query grammar (column projection, per-column filters, sorting, and pagination) and returns the standard `{ "error": ..., "data": ... }` envelope. Authenticate by sending your API key in the `X-Blockworks-API-Key` header. title: Blockworks Data API version: 0.1.0 servers: - description: Blockworks API url: https://api.blockworks.com security: -
