The primitives
Every AltPROP feature composes from these six primitives. If a workflow cannot be described in terms of them, we do not ship it.
FSBO, agent-represented, and rentals in one schema. Publishing is gated by the required seller authorization and identity verification. Cooperation modes handle office-exclusive and coming-soon.
Learn moreRegulated identity verification for consumers and professionals. AML posture on both card and stablecoin flows. One identity record, applied across the platform where compliance requires it.
Learn moreBuyer Broker Agreements, co-marketing agreements, and transaction-coordination engagement letters — e-signature-backed and treated as prerequisites, not paperwork.
Learn moreTokenized cards, Apple Pay, and Google Pay for everyday checkout. Custodial and self-custody stablecoin rails available where appropriate. USD is always the unit of account.
Learn moreThe platform charges for the connection, not the data. Provider leads, buyer-agent introductions, seller-side coordination. Same lane, different SKU. No inbox harvesting. No search-intent auctions.
Learn moreA metered credit ledger powers AI actions and higher-tier API use. Bundled monthly with FSBO+ and active PROP Realty agents; overage available in one-time packs.
Learn moreThe developer surface
Qualified sellers and active PROP Realty agents receive REST access, webhooks, and scoped API keys — metered against the same credit ledger that powers the AI tools.
Read/write your own listings, leads, offers, and coordination artifacts. Validated, rate-limited, and safe to retry. A generous monthly free grace before metering applies.
Signed, replay-safe delivery for listing lifecycle, offer events, and lead handoff. Automatic retry on transient failure.
Scope-limited keys issued from your dashboard. Rotate, revoke, and audit without a support ticket. Every request is attributed for compliance and billing.
Export what you have contributed — listings, leads, messages, credit ledger entries — as a signed archive. You own the data. We host the connections.
What makes it different
| Category | Legacy model | AltPROP |
|---|---|---|
| Legacy portals | Sell leads back to the industry | Sell software and services to the participants |
| MLS-only distribution | Access-gated, brokerage-only | Consumer-first with cooperative posture |
| Traditional brokerage | Sells service, absorbs the tech cost | Ships service and software as one product |
| Crypto-native listings | Requires wallets from every consumer | Wallets optional, cards default |
