Query active US for-sale property listings by location, price, property type, and more via pay-per-call MPP.
What it does
The RentCast Sale Listings endpoint returns current for-sale property listings across the United States. It is one of several endpoints in the RentCast suite hosted on the Locus MPP gateway, which also includes property records, AVM valuations, rent estimates, rental listings, and market statistics.
This specific endpoint (`/rentcast/sale-listings`) accepts POST requests with filters such as full address, city, state, zip code, latitude/longitude with radius, property type (Single Family, Condo, Townhouse, etc.), bedroom/bathroom counts, square footage, lot size, year built, listing status (Active/Inactive), listed price, and days on market. Ranges (e.g., `1:3`) and pipe-separated multiples (e.g., `1|3`) are supported for numeric filters. Results are paginated with `limit` (1–500, default 50) and `offset` parameters, and an optional `includeTotalCount` flag adds an `X-Total-Count` response header.
Payment is handled via the MPP protocol using the Tempo method (pathUSD on Tempo L2). Each call costs 33,000 base units; assuming pathUSD uses 6 decimals, that equates to $0.033 per request. The endpoint requires a POST with a JSON body — HEAD and GET probes returned 404, which is expected for a POST-only route. The broader RentCast API reference is available at developers.rentcast.io, and an LLM-oriented skill file is published at paywithlocus.com/skill.md.
Capabilities

- —Monitoring days-on-market trends for specific neighborhoods
- —Feeding listing data into an AI agent that recommends properties to buyers
- —Aggregating sale listing counts across zip codes for market coverage dashboards
Fit
Best for
- —AI agents needing programmatic, pay-per-call access to US sale listings
- —Developers building real estate search or comparison tools
- —Investors screening properties by price, size, and location filters
Not for

}Endpoint
Quality
Full OpenAPI schema with detailed request parameters and payment info is available. However, the endpoint returned 404 on HEAD/GET (expected for POST-only), no actual 402 challenge was captured for this specific path, no response schema or example response is documented, and crawled pages all returned generic 404 JSON. Pricing is inferrable but the currency token address is not fully confirmed as pathUSD with 6 decimals.
Warnings
- —No 402 challenge was captured for this endpoint; HEAD and GET returned 404. The endpoint is POST-only, so liveness could not be confirmed via the probe methods used.
- —No response schema is documented in the OpenAPI spec — only a generic '200: Successful response' description.
- —The currency token address (0x20c000000000000000000000b9537d11c60e8b50) is assumed to be pathUSD with 6 decimals based on the Tempo method context, but this is not explicitly confirmed in the probe data.
- —All crawled pages returned 404 with a redirect to skill.md / llms.txt — no additional documentation was retrievable.
