description: >-
  FinOps framework definition for the Arbiscan API surface. Provides a FOCUS-aligned mapping for cost
  allocation, usage measurement, and unit-economics reporting for teams consuming Arbitrum One blockchain
  data via the Etherscan V2 unified platform. Arbiscan API billing flows through Etherscan's Stripe-based
  subscription system with monthly auto-renewal.
principles:
  - name: Visibility
    description: >-
      Make Arbiscan API consumption costs visible to engineering, product, and finance teams in near
      real-time, including daily call volume against quota for each pricing tier.
  - name: Allocation
    description: >-
      Tag every chargeable API call with the consuming team, environment, application, and feature so
      cost can be allocated across teams querying Arbitrum One blockchain data.
  - name: Optimization
    description: >-
      Continuously evaluate request patterns, caching, batching, and tier selection to reduce cost per
      useful unit of blockchain data retrieved. Consider multicall batching and response caching where
      Arbitrum data is re-queried frequently.
  - name: Accountability
    description: >-
      Establish budget owners and chargeback or showback flows for each team consuming Arbiscan API
      capacity, aligned to the Etherscan V2 subscription tier in use.
