name: Vesper Finance API FinOps
description: Vesper Finance REST API is free to access with no usage-based charges.
  Cost considerations for integrators relate to on-chain transaction fees when
  interacting with Vesper smart contracts directly, and to infrastructure costs for
  running data pipelines that consume the public API.
costs:
  - name: API Access
    description: The Vesper Finance REST API (api.vesper.finance) is publicly
      accessible at no charge. No subscription, API key, or payment is required.
    amount: 0.00
    currency: USD
    unit: request
  - name: On-Chain Interaction Gas Fees
    description: Direct interaction with Vesper smart contracts (deposit, withdraw,
      rebalance, claimVsp) requires Ethereum or EVM-compatible gas fees paid in the
      native chain token (ETH, MATIC, AVAX). Gas costs vary by network congestion
      and operation complexity.
    amount: null
    currency: ETH
    unit: transaction
    notes: Gas fees are network-dependent and not controlled by Vesper Finance.
      Withdrawal and deposit operations on Ethereum mainnet typically cost between
      0.005 and 0.05 ETH depending on pool complexity and strategy count.
  - name: Vesper Protocol Performance Fee
    description: Vesper pools charge a 2% annual performance fee on deposited
      principal, taken at rebalance events, capped at 50% of earned yield. This fee
      is embedded in APY figures and is not a separate API charge.
    amount: 2.00
    currency: percent
    unit: year
    notes: Fee applies to protocol users, not API consumers. APY data returned by
      the API already reflects post-fee yields.
savings:
  - name: No Authentication Infrastructure
    description: Since the API requires no keys or OAuth, integrators save on
      credential management, rotation, and secure storage overhead.
  - name: Open Source Contracts
    description: Smart contracts are open source at github.com/vesperfi/vesper-contracts,
      reducing due diligence costs for integrations.
  - name: Public Subgraph
    description: The Vesper subgraph on The Graph provides an alternative free
      data access layer for historical on-chain data, reducing dependency on the
      centralized REST API.
