Managed Oracle Services
dAPIs are data feeds built entirely on-chain
from first-party, API provider-operated oracles
with decentralized governance.
where it matters
API3 data feeds are governed by an open DAO of stakeholders, industry experts and project partners. This allows dAPIs to be operated with maximal transparency, minimal required trust in centralized operators, and no centralized attack surfaces. API token holders can take a direct part in governing the project by staking API3 tokens into the API3 coverage staking contract, which grants them voting power in the API3 DAO.
by API providers
Without third-party node operators, API3 data feeds are never exposed to data tampering by middlemen or denial of service attacks. This enables them to reach higher cost-efficiency, while having a smaller attack surface. Source-level decentralization of dAPIs is enabled by Airnode, a fully serverless oracle node that can be deployed by any API provider for free, and requires minimal day-to-day management.
API3 provides dAPI users with on-chain coverage from risk, powered by the API3 token and Kleros’ decentralized courts. API3’s coverage feature gives dAPI users a quantifiable safety net in the event of a malfunction, holds the API3 DAO directly accountable for the security of the dAPIs and incentivizes a security-first governance approach for dAPIs and the API3 project as a whole.
to any blockchain
As a multi-layer, cross-platform data solution, dAPIs can be bridged to any blockchain, in order to provide smart contracts on various platforms with reliable access to premium real-world data. API3’s cross-platform approach enables any smart contract platform to leverage API3’s ecosystem of dAPIs and data-integration tools by simply creating a bridge between API3 and the network.
