RealBase
Self-sustaining autonomous agent for SF affordable housing data
RealBase aggregates data from 7 sources (schools, crime, transit, walkability, census, DAHLIA listings, rental market) to score San Francisco neighborhoods and help people find affordable housing. It runs autonomously on Base blockchain, earning revenue through x402 API payments, NFT reports, and an onchain data oracle.
x402 Data API
Pay-per-request neighborhood data API. Other agents and developers pay USDC for real-time SF housing insights.
NFT Reports
ERC-721 neighborhood analysis snapshots minted on Base. Frozen-in-time data with school ratings, crime stats, and more.
Onchain Oracle
Smart contract storing neighborhood scores that other contracts can query for a fee.
