}LinkedIn → Hashed Emails
Get hashed email variants for a profile, ready for ad-platform matching.
linkedin_slug accepts either a bare slug (e.g. alice-123) or a full profile URL (e.g. https://www.linkedin.com/in/alice-123). On a match, the response contains the hashed email variants known for the profile (e.g. md5_1, sha256_1, md5_2, …); ready for ad-platform audience matching.
Billing: 1 credit per successful match (HTTP 200). Misses (404) and request errors (4xx) are not billed.
