## Before you call it

1. Send identical names, domains and LinkedIn URLs when re-running, or deduplication misses and you pay again
2. Expect 30 to 90 seconds a contact. Use the webhook or poll `get_enrichment_results`
3. Ask for mobiles only when needed. They cost 10 credits against 1 for a work email
4. Call `list_industries` and `list_seniorities` before filtering search
5. Use the 0-credit test contacts in the docs to check an integration
