  API3 dAPI subscriptions are purchased through the API3 Market on a self-serve, pay-as-you-go
  basis with no contracts or sales conversations required. Pricing reflects estimated operational
  gas costs for maintaining update thresholds and heartbeat — or $0.05/day, whichever is higher.
  Testnet plans run for 7 days; mainnet plans run for 3 months. Unused prepaid gas rolls over as
  a credit on the same chain+feed pair. OEV Rewards integration is free — revenue flows from the
  OEV auction pool rather than from the dApp. Airnode deployment and the HTTP gateway are
  open-source and self-hosted; there are no API3 per-call fees for Airnode gateway usage.

    description: >-
      7-day testnet subscription for a single dAPI feed on a supported testnet network.
      Allows developers to integrate and test Api3ReaderProxyV1 contracts before committing
      to a mainnet plan. No payment required on testnets.
    entries:

    description: >-
      3-month mainnet subscription for a single dAPI feed on a supported EVM network.
      Priced at estimated operational gas costs to maintain the selected deviation threshold
      and heartbeat interval, with a minimum of $0.05/day. Any over-estimated gas accrues
      as credit toward the next renewal on the same chain and feed pair.

    name: OEV Rewards (Revenue Share)
    type: revenue-share
    description: >-
      Free integration tier that enables dApps to receive 80% of OEV auction proceeds
      generated around their oracle updates. Requires deploying a custom OEV-enabled
      Api3ReaderProxyV1 proxy via the API3 Market and registering a recipient wallet with
      an API3 representative. Payouts are in the native gas token of the dApp chain,
      distributed monthly. No upfront cost; revenue comes from third-party MEV capture.
