Deal-level US multifamily real-estate data for AI agents, pay-per-call in USDC on Base (x402 v2, Coinbase CDP facilitator). Typed underwriting on every record (NOI, DSCR, HUD-SAFMR-underwritten cap rate), Hot/Warm/Pass scoring with machine-readable rationales, county tax-delinquency distress signals, sheriff-sale auction calendar, scored off-market seller leads, and a per-address lookup. Every absent value carries a typed reason, and a query that matches nothing returns free — you never pay for a blank.
Pay from $0.01 to $1.00 in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

] OVER TIME
All charts share the 7d window selected here. Every series is also served as JSON at /api/v1/services/dwelldata-multifamily-real-estate-deals-feed/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
