Centris Batch saved observations API

Read up to 25 saved observations with individual outcomes. Get structured JSON through one RealtyCrawl API key.

Send resources as one to 25 unique operation/id pairs from this account. Use returned RealtyCrawl resource IDs and a read operation supported for the selected source. Each successful read costs one credit; this request makes no source calls and does not renew retention. This operation reads an account-owned retained observation. It does not refresh the source; inspect its collection time and retention limits. Check live capabilities for accepted inputs and availability before running your request.
