Api3 Plans
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.
Api3 Plans is the machine-readable pricing-plan profile for API3 on the APIs.io network, conforming to the API Commons Plans specification.
It defines 3 plans, covering trial, usage-based, and revenue-share tiers, with named plans including Testnet Trial Plan, Mainnet Standard Plan, OEV Rewards (Revenue Share).
Tagged areas include Blockchain, Oracle, Data Feeds, dAPI, and OEV.

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.
- Custom OEV-enabled proxy contract
