Inspect the historical review dataset before you pay.
Use this page in cold emails to operators and customer-experience teams that want files first. Leave a work email, download the CSV/JSON sample, inspect the chain signal (sentiment momentum across 100% of each chain’s history), audited sentiment fields, sentiment_method, coverage manifest, and latest review timestamp, then decide whether monthly 30-day or weekly 7-day delta packs are worth diligence.
Sample files
Free signal-first sample: no-text evidence rows, chain signals, daily aggregates, licensed sentiment fields, coverage manifest, schema, methodology, source-rights summary, and lite license terms. The files are diligence evidence, not a forecast or performance guarantee.
