Waterfall enrichment

Waterfall enrichment is a lookup strategy that tries multiple data providers in sequence for the same request until one returns a result. RichAPI bills full price only when a provider returns a hit — a miss costs half or less, and a provider failure costs nothing.

Data enrichmentData enrichment is the process of taking a partial record — a name, an email, a LinkedIn URL, a company domain — and filling in the missing fields from external sources: job title, company, location, work history, firmographics. In RichAPI it's a single API call, such as enrich_profile, that returns the structured record.
