What are the pros of API3?

First-party model removes third-party oracle middlemen. OEV lets protocols recapture oracle value. Transparent, source-direct data feeds. Broad multi-chain feed coverage.

What are the cons of API3?

EVM-first; no native Solana program integration. Solana access is only indirect via Neon EVM. OEV and dAPI concepts add integration complexity.

How much does API3 cost?

API3 is completely free to use.

API3 Review | Honest Verdict (2026)

API3 is a first-party oracle network that lets data providers run their own oracles and deliver real-world data on-chain without third-party middlemen. It also pioneered Oracle Extractable Value (OEV), letting projects recapture value from oracle updates that would otherwise leak to searchers. Providers operate Airnode-based first-party oracles that feed dAPIs (decentralized API data feeds), with over 100 feeds and an OEV auction mechanism that returns rewards to the integrating protocol. Projects browse and integrate feeds through the API3 Market. API3 targets DeFi builders who want transparent, source-direct price and data feeds. Importantly, API3 is an EVM-first project: its feeds and OEV Network deploy across dozens of EVM chains, and its only Solana-adjacent availability is through Neon EVM, an EVM compatibility layer on Solana, rather than native SPL/Solana-program integration. Teams building directly on native Solana should verify that API3 fits their stack before relying on it.
