About API3

API3 is a decentralized oracle protocol that enables API providers to run their own oracle nodes using Airnode technology, eliminating intermediaries. Its core business includes offering dAPIs (decentralized APIs) for smart contracts and an OEV (Oracle Extractable Value) mechanism that auctions update rights, returning 80% of proceeds to dApps.

The market pain point is that traditional oracles like Chainlink rely on third-party relayers, creating opacity and value leakage. API3 solves this by letting data sources operate nodes directly, ensuring transparency, verifiable signatures, and lower costs. Its competitiveness lies in first-party oracles, broad chain coverage (40+ chains, 200+ feeds), and the OEV revenue-sharing model.

In the past six months (Feb-Aug 2026), API3 expanded integrations with lending protocols like Compound and Moonwell, and OEV rewards surpassed $281,000, with a target of $1 million by year-end. However, in 2023, API3 faced criticism over token price volatility and delayed mainnet launches, and its governance token saw significant drawdowns. No major security incidents were reported in the period.

API3 launched in December 2020 as a first-party oracle network, enabling data providers to run nodes directly via Airnode, eliminating third-party intermediaries and achieving verifiability down to the data source.

In January 2024, API3 introduced the OEV Network concept to capture oracle extractable value (OEV) through order-flow auctions and return it to dApps. In May of the same year, it completed a $4 million financing round led by DWF Labs to support the mainnet launch.

Subsequently, the OEV Network pivoted to building on Arbitrum Orbit to improve execution efficiency, scalability, and cost-effectiveness. The OEV Network mainnet then officially launched, becoming the first L2 network to return protocol MEV through on-chain auction mechanisms.

Additionally, API3's TVS surpassed $1 billion, indicating widespread adoption of its data feeds in the DeFi ecosystem.

Positive factors: DAO approved allocating OEV, curator fees, and ETH staking yields to recurring market purchases (Sep 2026). Q3 2026 funding proposal passed, earmarking funds for treasury management and monthly API3 buybacks.

Negative factors: 24-hour trading volume was zero, indicating thin liquidity and subdued market activity.
