[October 2025] - Legacy Format Deprecation Notice + Realtime Data
BREAKING CHANGE: The legacy response format will be deprecated on November 1st, 2025.The modern format is significantly more complex with 97+ profile fields, nested models, and detailed type safety. Review the full type definitions before migrating.
🚀 New: Realtime Data Updates
All API endpoints now return realtime data:- Profile information is continuously updated
- Company details reflect current status
- Engagement metrics (connections, followers, posts) are live
- Experience changes are tracked and identified in real-time
- No more stale data - always get the most current information available
Affected Endpoints
GET /api/search- Search PeopleGET /api/search/deep_research/{job_id}- Get Deep Research StatusGET /api/enrich/linkedin- Get LinkedIn Profile
Migration Complexity Warning
The modern format contains significantly more data than the legacy format. A single profile response can include:
- 97 profile fields (vs 10-15 in legacy)
- 48 experience fields per job (vs 10-15 in legacy)
- Complex nested objects for breakdowns and change tracking
- Detailed company information including financials, stock data, geographic details
- Structured date fields with separate year/month instead of formatted strings
- Type-safe arrays instead of string representations
Implementation Details
Response Format Migration
The API supports both formats during the transition period:- Default (Modern): Full type-safe models with extensive data
- Legacy: Simplified format using transformation functions
- Migration Period: Both formats supported until November 1st, 2025
