## Before you call either

### Enrich Layer API + MCP

1. Top up once before testing. Trial keys run at 2 requests a minute
2. Set the person profile timeout to at least 100 seconds
3. Ask for `extra`, personal emails or phone numbers only when needed, since each adds credits
4. Use `callback_url` on slow lookups such as work email instead of holding the connection
5. Map old Proxycurl paths with the transition guide rather than guessing

### Lusha API + MCP

1. Batch up to 25 contacts a request. A single bulk request costs 1 credit, not 1 per contact
2. Ask for phones only when needed. A phone is 5 credits against 1 for an email
3. Use the Buying Group endpoint. Decision Makers was retired on 2026-09-04
4. Use `/v3/lookalike/contacts` for contact lookalikes
5. Back off exponentially on 429. Free keys stop at 100 requests a day
