# How do we build an enrichment waterfall without wasting credits?

Order providers by cost and hit rate for the specific field, stop at first match, and never call a provider for a record you already resolved. Enrich only the fields your routing, scoring and territory rules actually read — everything else is spend with no decision attached.

Track hit rate per provider per field so the order can be re-tuned with evidence rather than vendor claims. Add an enrich-status field and a fallback queue: the records nobody can resolve need an owner, or they become the invisible pile that makes routing look broken.
