Property Data API Without Subscription

Look up valuations, rents, and comparables with RentCast pay-per-request — check coverage and current pricing for each lookup.

How do I get property data without a data subscription?

Short answer: query RentCast through Locus and pay per lookup from one balance. Check current endpoint prices, geographic coverage, and data freshness before a research batch. Automated estimates are inputs to research and do not replace an appraisal or due diligence.

What property data can I get pay-per-use?

Why investors fit pay-per-request

•Deal-based usage — You analyze properties when deals appear — a few lookups per deal, then nothing. Plans charge between deals too.
•Side-project friendly — Testing an investor tool or building a search agent should cost dollars in data, not a plan signup.
•Agent underwriting — An AI agent that pulls valuation, rents, and comps into a deal memo pays per lookup inside the workflow.

Build a property research brief

A typical flow: valuation plus rent estimate plus a handful of comparables for the subject property, summarized by an LLM into a one-page memo. A few lookups per deal at catalog per-request prices keeps the data cost far below the value of one avoided bad offer.

Connect and control usage

Locus Pro uses prepaid credits. Start with the agent connection guide, review current plans, and configure spending controls before scaling a workflow. Pay With Locus is the separate on-chain wallet product.
