Full profile per reactor — headline, current company, profile URL included by default.
Classified errors — every error is tagged client (your input/access) or transient (our side or upstream), so your retry logic stays clean.
No LinkedIn account — zero account-burning risk.

Errors & limits

INVALID_INPUT — malformed post URL.
POST_NOT_FOUND — post is private, deleted, or you don't have access.
RATE_LIMITED — temporary throttle; retry with backoff.
