"What is Api3?
Api3 delivers first-party oracles that pay you.
By connecting real-world data providers directly to smart contracts, Api3 eliminates intermediaries, ensuring unmatched transparency and security. With pioneering mechanisms to recapture Oracle Extractable Value (OEV), Api3 empowers dApps with reliable data while minimizing and reclaiming the value they would otherwise leak to external actors. Api3 is redefining the oracle space by elevating oracles from mere data providers to entities that help builders retain the value they create.

Api3: First-Party Oracles That Pay You
Api3 is redefining the oracle space by delivering first-party oracle infrastructure designed to minimize trust, maximize transparency, and return value to builders.
Instead of relying on third-party intermediaries, Api3 enables real-world data providers to operate their own oracles—offering direct, native access to off-chain data with unmatched integrity and reliability. By eliminating middlemen, Api3 removes central points of failure and enhances on-chain data provenance.
At the heart of the Api3 stack is the OEV Network, a groundbreaking innovation that enables pioneering mechanisms to recapture Oracle Extractable Value (OEV)—value that protocols typically lose to MEV bots. With Api3, that value is reclaimed at the oracle level and returned to the dApps that generate it, aligning incentives and enabling a new era of economically optimized oracle feeds.
Key Features:
- First-Party Oracles
Real-world data providers run their own oracles directly on-chain, eliminating intermediaries and enhancing transparency, security, and trust.
- dAPIs (Decentralized APIs)
Aggregated, verifiable, and on-chain accessible APIs built from first-party data sources. Simple to integrate, powerful in practice.
- The OEV Network
Capture Oracle Extractable Value through the oracle itself, not external bots. The OEV Network supports 43+ chains and over 150 asset feeds, unlocking new value flows for dApps that integrate with Api3.
- DAO Governance
Api3 is governed by its DAO, with proposals, funding, and protocol upgrades driven by community stakeholders in a transparent, decentralized manner.
Getting Started with Api3
- Explore the Api3 Market (market.api3.org)
Browse live oracle feeds and integrate them with just a few lines of code.
- Read the Docs
Check out our Developer Documentation for in-depth guides, references, and integration examples.
- Enable OEV Rewards
Integrate with the OEV Network and start reclaiming the value your dApp generates—because oracles should pay you, not others.
- Join the DAO
Participate in shaping the future of oracle infrastructure through open governance and community collaboration.
Use Cases:
- DeFi Lending & CDP Protocols
Access native, tamper-resistant price feeds that reduce slippage, minimize MEV exposure, and return OEV rewards directly to your protocol.
- Any dApp That Depends on Real-World Data
Whether you’re building prediction markets, synthetic assets, or advanced automation tools, Api3 ensures your data source is verifiable, secure, and economically aligned with your protocol.
Conclusion
Api3 is not just an oracle provider—it’s a platform for reclaiming control and value in Web3.
By combining first-party oracle infrastructure with mechanisms to recapture OEV, Api3 empowers builders to create smarter, safer, and more profitable dApps. Whether you're launching a DeFi protocol or scaling across multiple chains, Api3 gives you oracles that pay you."
