## Verdicts

**Dropcontact API + MCP.** Pay on success, with credits refunded when no email is found. No OpenAPI spec, llms.txt or changelog.

## Before you call either

### Dropcontact API + MCP

1. Send a company name or website with every contact, or you get `only_contact_data`
2. Send only documented fields. New accounts get a 400 for unknown ones
3. Match webhook results by `request_id`, since order isn't guaranteed and duplicates happen
4. Poll no faster than every 30 seconds, as the not-ready response asks
5. Post an empty contact to read the credit balance at no cost

### 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
