Estimate the Long-Term Rent of a US Home with Comparable Rentals
Estimate what a US home would rent for on a long-term lease and get back the monthly rent, a low and high range around it, the subject property's own attributes, and the comparable rental listings the estimate rests on — each with its address, attributes, asking rent, listing status and dates, days on market, distance in miles, age in days and a similarity score. Identify the home by full address or by latitude and longitude, and optionally override its property type, bedrooms, bathrooms or square footage, widen the comparable search radius, limit how old comparables may be, or ask for between 5 and 25 of them.

}This Endpoint publishes no output schema. You get the Provider's own response body, unchanged — we do not warrant a shape we cannot guarantee.
How to run it
Two fields identify it: the Provider and the endpoint key. The key looks like a path because it usually mirrors the Provider's own, but it is an opaque identifier — not a URL you can open. The same provider:endpoint pair is what your Policy lists.
Once: paste this into your agent's chat. The Skill installs the CLI and logs in by itself. For an agent that cannot use a shell, connect it over MCP instead.
set up https://glasser.ai/SKILL.mdThen ask for this Endpoint:
Run the RentCast Endpoint /avm/rent/long-term on Glasser with input {"address":"5500 Grand Lake Dr, San Antonio, TX, 78244"}glasser run -p rentcast -e '/avm/rent/long-term' -i '{"address":"5500 Grand Lake Dr, San Antonio, TX, 78244"}' --endpoint-version 1Pinned to version 1, the one this page shows: if a newer version is published first, the Run is refused instead of charged under new terms. Install and log in first on Get Started.
Once per Run:
IDEMPOTENCY_KEY=$(uuidgen)Run it, and copy this same block to send it again:
curl -X POST https://api.glasser.ai/v1/runs \
-H "Authorization: Bearer gl_..." \
-H "Idempotency-Key: $IDEMPOTENCY_KEY" \
-H "Content-Type: application/json" \
-d '{"provider":"rentcast","endpoint":"/avm/rent/long-term","input":{"address":"5500 Grand Lake Dr, San Antonio, TX, 78244"},"endpoint_version":1}'Reuse the same Idempotency-Key to send it again: the second send is a read of the first Run. A new key is a new Run and a new Charge. Pinned to version 1 for the same reason as the CLI.
