Company Overview

API3 is a decentralized oracle solution revolutionizing how blockchain applications access off-chain data. The platform provides 200+ data feeds across multiple networks, distinguished by its first-party oracle model where API providers operate their own nodes, eliminating middlemen and reducing attack vectors.

Core Products

First-Party Oracles (Airnodes)

API providers operate their own oracle nodes directly, eliminating third-party intermediaries. This architecture reduces trust assumptions, lowers costs, and increases data reliability.

dAPIs (Decentralized APIs)

Decentralized data feeds aggregating data from multiple first-party oracles. Provides robust price feeds with built-in redundancy and manipulation resistance.

OEV Network (Oracle Extractable Value)

Innovative system returning value captured during oracle updates back to DeFi protocols. Over $363K in OEV rewards already distributed to lending protocols.

Key Features

Quantifiable Security

API3 provides provable security guarantees through on-chain insurance, offering measurable protection for oracle consumers.

200+ Data Feeds

Comprehensive coverage of crypto assets, forex pairs, and commodities across major blockchain networks.

Multi-Chain Support

Live on Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, and many other networks.

Technical Differentiators

• First-Party Model: API providers run nodes directly, no middlemen
• OEV Capture: Returns MEV-like value to protocols
• DAO Governance: Community-driven development and operations
• Open Source: Transparent, auditable infrastructure

Target Clients

• DeFi protocols requiring reliable price feeds
• Lending platforms seeking OEV revenue
• DEXs needing accurate pricing data
• Cross-chain applications requiring multi-network oracles
