description: >-
  FinOps view of Linea API consumption. The cost model is mixed: the public JSON-RPC endpoint and
  Token API are free-at-point-of-use (no subscription fee) but carry IP-level rate limits that
  push production workloads toward paid private node providers (Infura, Alchemy, QuickNode) billed
  on their own plans. The Lineascan explorer API follows the Etherscan V2 subscription ladder
  ($0 Free → $49 Lite → $199 Standard → $299 Advanced → $399 Professional → custom Enterprise),
  unified across all 50+ supported EVM chains under one API key and billing account. Teams should
  budget: (1) a Lineascan tier for explorer data needs, (2) a private RPC node plan for
  transaction submission and eth_* queries at scale, and (3) minor egress/compute for on-chain
  gas fees when submitting transactions.

principles:
  - name: Visibility
    description: >-
      Tag each Lineascan API key and private RPC endpoint to a single owning workload or team.
      Separate keys per service enable accurate usage attribution and quota isolation.
  - name: Allocation
    description: >-
      Allocate Lineascan subscription cost to the products consuming explorer data. Allocate
      private RPC costs to the workloads making RPC calls. Track on-chain gas separately as
      a transaction cost line item.
  - name: Optimization
    description: >-
      Right-size the Lineascan tier based on peak calls/second and daily volume. Cache Token API
      responses to stay within the 60 req/min free limit. For RPC, choose the cheapest node
      provider tier that meets your p99 latency and throughput requirements; avoid the public
      RPC in production.
  - name: Accountability
    description: >-
      Assign a billing owner to the Lineascan account and to each private RPC provider
      subscription. Review at monthly renewal; cancel unused API keys promptly.
  - name: Forecasting
    description: >-
      Model explorer API cost as a step function at the Lite/Standard/Advanced/Professional
      boundaries. Forecast RPC costs based on transaction volume and read-call frequency.
      On-chain gas is variable; use linea_estimateGas before submitting to bound per-transaction cost.
