Equals the total when `window=block`. | ## OpenAPI ````yaml openapi/v2-onchain.json GET /network/contract-calls-count openapi: 3.0.0 info: version: 2.0.0-beta title: CryptoQuant Data API v2 — On-chain description: >- On-chain endpoints of the CryptoQuant Data API v2 — network activity, exchange and mining pool flows, indicators, and capitalization, for Bitcoin and for Ethereum with the ERC-20 and stablecoin assets issued on it. One path serves every asset: the asset is a query parameter, not part of the path. Built on the v1 conventions: the `status`/`result` envelope, Bearer token authentication, and the `window`/`from`/`to` time parameters. termsOfService: https://cryptoquant.com/terms-of-service contact: name: API Support email: contact@cryptoquant.com servers: - url: https://api.cryptoquant.com/v2 description: Default server security: [] tags: - name: Network Data - name: Exchange Flows - name: Mining Pool Flows - name: Inter-Entity Flows - name: Indicator - name: Market Data paths: /network/contract-calls-count: get: tags: - Network Data summary: Contract Calls Count description: >- The number of contract calls in the window, internal and external together. operationId: V2NetworkContractCallsCount parameters: - name: asset in: query required: true description: >- Asset to query, by its CryptoQuant alias (no chain suffix — `usdt`, not `usdt_eth`). 1 asset is available on this endpoint, across the asset class `eth`.
