## Before you call either

### FullEnrich API + MCP

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

### LeadMagic API + MCP

1. Call `preview_cost` before bulk work. It's free
2. Read `X-Credits-Remaining` after each call instead of polling the balance
3. Treat 402 as out of credits and wait out Retry-After on 429
4. Keep credit-free search under 13,333 calls a day per account
5. Retry `unknown` validations later. They cost nothing
