Parcl

Parcl is a New York-based company that publishes live U.S. residential housing market data. Its website presents daily-updated metrics for markets nationwide — year-over-year price change, months of supply (MSI) and the share of listings with price cuts — at the national, state, metro, county, city and zip level. The company describes coverage of 150 million properties, 70,000 markets and 1.5 million investors, with more than 20,000 daily price feeds and roughly 1.6 million active listings priced on the day of capture.

The product set advertised on the site comprises four components: Parcl HQ, for accessing live price, mortgage, seller-motivation and rental data for U.S. markets; Housing Research, publishing data-driven reports on U.S. housing trends; Data Vault, which delivers property, market and investor data via API or MCP; and a Prediction Markets section that tracks how housing prediction markets resolve, verified against Parcl price indices. Users can create watchlists to track selected markets.

Parcl also maintains developer documentation for Parcl v3, described as a perpetuals exchange for real estate synthetics supporting cross-margined perpetual trading on real estate markets, with liquidity providers contributing to a single LP pool per exchange, absorbing trader PnL and earning trading fees. Market index prices used by the exchange are price feeds created by Parcl Labs, streamed on-chain through Pyth oracles operated by the Parcl development team; that documentation page was last updated roughly a year before capture. An earlier company description on Built In NYC characterizes Parcl as a blockchain-based platform for investing in a "digital square foot" of physical real estate in neighborhoods worldwide, tracked by the Parcl Price Index, with no investment minimum, immediate liquidity and low transaction fees.
