Decentralized APIs for Web 3.0
Create powerful decentralized applications with API3’s decentrally governed and quantifiably secure data feeds.
Connect Smart Contracts to Real-World Data
API3 data feeds, dAPIs, aggregate data from first-party oracles, operated by some of the world’s premier API providers.
Features
DAO - Governed
Decentralized, trust-minimized and transparent governance.
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 insurance staking contract, which grants them shares in the API3 DAO.
Data Provider - Operated
First-party oracles instead of third-party middlemen.
Without third-party node operators, API3 data feeds are never exposed to data tampering and denial of service attacks by middlemen. This enables them to reach higher cost-efficiency, while having fewer attack surfaces. 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.
Quantifiably Secure
Users insured against data feed malfunctions.
API3 provides dAPI users with the option of on-chain insurance, powered by the API3 token and Kleros’ decentralized courts. API3’s insurance feature gives dAPI users a quantifiable safety net in the event of a malfunction, holds the API3 DAO directly responsible for the security of the dAPIs and incentivizes a security-first governance approach for dAPIs and the API3 project as a whole.
Cross - Platform
Real-world data for any smart contract platform.
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.
API3 TOKEN
The Governance Token of the API3 DAO
API3 is the native token of the API3 project. It gives its holders the right to take part in the governance of the API3 ecosystem through the API3 DAO. To generate shares in the API3 DAO, token holders have to stake the API3 tokens into the insurance pool, which also gives them access to weekly staking rewards.
Insurance staking pool
By staking your API3 tokens into the insurance staking pool, you take part in providing API3 users with quantifiable security guarantees in the form of insurance. Insurance staking pool funds are used to cover potential financial losses from dAPI malfunctions that the dAPI consumer might incur. As you stake API3 to the insurance pool, you generate shares in the API3 DAO.
