Realtor MLS ID Lookup API - Resolve Public Listing References

Pass a known MLS listing reference as mlsId; page and pageSize are optional numeric inputs. The documented example is a listing number, not a city name. This lookup was not live-tested, so returned property fields, reference ambiguity and pagination have not been confirmed. Check any returned identity against the intended property and geography before linking records. MLS reference lookup does not provide direct MLS access, an IDX license, comprehensive MLS coverage or permission to redistribute a listing.

API Features

MLS-number request key Supply the listing reference as mlsId rather than substituting a property_id or a location string.

Reference reconciliation scope The route is intended for public listing lookup; confirm any returned identity before joining records.

Optional result paging inputs Numeric page and pageSize remain available for evaluation without a verified pagination guarantee.

No MLS access implication A reference lookup is distinct from a licensed MLS/IDX data feed or republication authorization.

Frequently asked questions

Are mlsId and property_id interchangeable?

No. mlsId is a known MLS listing reference, while property_id identifies a property. Use the correct input and verify returned address and property identity.

Does an MLS number guarantee a unique property match?

No. Reference ambiguity and response behavior were not live-tested. Check geography and property identity before joining records; do not match solely on the reference number.

Does MLS reference lookup grant MLS or IDX rights?

No. Public reference lookup does not grant MLS data access, an IDX license or permission to republish photos and text. Establish applicable rights separately.
