1. Waterfall enrichment follows a cascading query pattern with configurable logic. “Providers are ranked by accuracy, coverage, and cost for each data type.” Sequential querying sends each record to the first provider. If the provider returns data for all requested fields, the record is complete and no further queries are needed. If some fields remain empty (no phone number found, or no verified email), the record passes to the next provider with only the unfilled fields requested.

If some fields remain empty (no phone number found, or no verified email), the record passes to the next provider with only the unfilled fields requested. “Match confidence scoring evaluates the quality of each provider's response.” Deduplication and conflict resolution handles cases where multiple providers return different values for the same field. Rules determine which provider's data wins: some organizations prioritize the most recently verified data, others prefer specific providers for specific fields, and some use majority-vote logic (if 2 of 3 providers agree, that value is used).
