View ChartThis article covers the API3 oracle project and its API3 token on Ethereum; it is unrelated to any other project using a similar name. API3 (API3) is an Ethereum-based cryptocurrency and oracle infrastructure project that powers decentralised APIs, known as dAPIs, connecting real-world data providers directly to smart contracts. The project's core technology is first-party oracles, in which data providers run their own oracle nodes on-chain rather than routing data through third-party intermediaries. This design is intended to improve security, transparency, and data-source integrity. The API3 whitepaper was unveiled in September 2020, and the token went live in early December 2020 following a token sale. API3 operates as a DAO, meaning token holders govern the network's direction and upgrades. The token has no fixed maximum supply, and the founding team holds a 30.00% allocation. API3 has raised $3M in funding from Placeholder, and the token sale generated tens of millions of dollars. The project employs 23 people. API3's positioning centres on a simple proposition: oracles that pay you, with revenue from OEV, Curator fees, and ETH staking yield channelled back into the ecosystem.
API3 is a Cayman Islands-based decentralised technology organisation (based in George Town) that develops first-party oracles and decentralised APIs. API3 was co-founded by Heikki Vänttinen, who serves as CEO, and Burak Benligiray, who authored the project's whitepaper titled "Decentralised APIs for Web 3.0." Saša Milić is also identified as a co-founder. Heikki Vänttinen is based in Bangkok, Thailand, and has been associated with Zippie, Equilibrium Labs, and Aava & Bang. The project's founding team holds a 30.00% token allocation. The team has grown to 23 employees. The whitepaper, authored by Burak Benligiray, has been cited 33 times and presents a structured plan for creating secure, cost-efficient, and transparent decentralised APIs.
API3 replaces legacy third-party oracle networks with first-party oracle solutions. In this model, real-world data providers operate their own oracle nodes directly on-chain, eliminating intermediaries and improving transparency and trust. These data sources are aggregated into dAPIs, which are verifiable and accessible on-chain, and can be integrated with just a few lines of code. The OEV Network is a core innovation that recaptures Oracle Extractable Value, which protocols typically lose to MEV bots. By reclaiming this value at the oracle level and returning it to the dApps that generate it, API3 aligns incentives and creates more economically optimised oracle feeds. The OEV Network supports 43+ chains and over 150 asset feeds, while API3 reports 100+ data feeds on every chain. API3 also offers AirnodeHub, an early-access marketplace where agents can discover, call, and pay for APIs autonomously, with data sources compensated for every response.
API3's primary differentiator is its first-party oracle architecture, which removes intermediaries between data providers and smart contracts. This approach is designed to deliver more security, efficiency, and data-source integrity than legacy third-party networks. The OEV Network further distinguishes API3 by enabling dApps to recapture value that would otherwise leak to MEV bots, turning oracles from a cost centre into a potential revenue source. The project's tagline, "Oracles that pay you," reflects this value proposition. API3's stated goal is to allow decentralised versions of APIs to be built, managed and monetised at scale. With 100+ data feeds on every chain and a DAO governance model, API3 offers builders a transparent and economically aligned data infrastructure.
API3 powers the API3 project, which connects traditional APIs with the blockchain ecosystem. The token is used within a DAO where holders govern the network's direction and upgrades, with proposals, funding, and protocol upgrades driven by community stakeholders. API3 is also central to the project's value flows: OEV revenue, Curator fees, and ETH staking yield are channelled into recurring market buys of API3, per an approved DAO decision. The token supports the broader ecosystem, including dAPIs, the OEV Network, and AirnodeHub. Target users include DeFi lending and CDP protocols, prediction markets, synthetic assets, advanced automation tools, and any dApp that depends on real-world data. API3's infrastructure is designed for builders launching DeFi protocols or scaling across multiple chains.
The API3 ecosystem is expanding through several active components. The Api3 Market allows users to browse live oracle feeds and integrate them with minimal code. The OEV Network supports 43+ chains and over 150 asset feeds. Total OEV Rewards Paid stand at 416,069 USD, with totals updated through the 7th of each month. AirnodeHub is in early access as a marketplace for agents to discover, call, and pay for APIs, with data sources earning revenue for every response. API3 reports 100+ data feeds on every chain. API3 operates as a DAO, and voting power is snapshotted during proposal creation. Recent governance activity includes an approved DAO decision to channel OEV revenue, Curator fees, and ETH staking yield into recurring market buys. API3 trades on around 250 active markets (Yahoo Finance).
API3 is not mined. It is an ERC-20 token on Ethereum secured by Ethereum's proof-of-stake consensus, and holders participate through DAO governance rather than block rewards. ETH staking yield is channelled into recurring market buys of API3 per an approved DAO decision. Data providers can run first-party oracle nodes and earn revenue for their services, while dApps can integrate dAPIs and potentially earn OEV Rewards.
Keeping API3 safe requires attention to several risk factors. Smart contract risk is a concern, as vulnerabilities in smart contracts may be exploited and lead to significant losses. Scam risk is also present, with bad actors potentially launching tokens with no real intention of developing the project. Data risk exists because some protocols rely on external data sources that may be vulnerable to attack, which could result in disruption and devaluation. Protocol complexity can make DeFi protocols challenging to understand. As Revolut warns, don't invest unless you're prepared to lose all the money you invest; this is a high-risk investment and you should not expect to be protected if something goes wrong. Crypto is not regulated or protected and is volatile. Thin liquidity can amplify price drops, so trade sizes should be sized with care. Using reputable wallets, verifying contract addresses, and staying informed about exchange delistings and regulatory events are practical precautions.
API3 is listed on several major exchanges; liquidity varies by venue and should be checked before trading. API3 can be purchased on a reputable, regulated platform after completing identity verification.
