Obtain API credentials through a Cotality data licensing agreement and authenticate to the API using the provided OAuth token endpoint
Submit a property lookup by address or APN to the CoreLogic Address Matcher endpoint to retrieve the canonical CoreLogic property identifier (clip ID) for the target parcel
Call the property detail endpoint using the clip ID to retrieve assessed value, land use classification, building characteristics, and owner of record data
Call the tax assessment history endpoint to retrieve multi-year assessed value history, tax amounts, delinquency flags, and exemption types
Call the deed transaction history endpoint to retrieve the chain of title including sale price, grantee/grantor names, document type, and recording date for each transfer
Call the property risk endpoint (if licensed) to retrieve natural hazard risk scores including flood, wildfire, earthquake, and wind, which are relevant for insurance and lending decisions
Known gotchas
CoreLogic's API is licensed by data product; a standard property detail license does not include tax history, deed transactions, or risk scores—confirm which data products are included in your agreement before building integrations that assume access
The Cotality branding (rebranded from CoreLogic in 2025) affects API domain URLs and some product endpoint paths; validate all endpoint base URLs against current documentation rather than using paths from pre-2025 integrations
Property records in counties with delayed recording can have deed transaction data that lags 30–90 days behind actual closing; do not treat a missing recent deed as confirmation that no transfer has occurred
