September 2026
- Added dedicated REST references for the Profile, Profile Posts, Company, and Company Posts APIs. Each endpoint accepts a known public record and returns a synchronous structured response.
- Added a four-API overview and a Profile API quickstart with bearer-key authentication, query parameters, response examples, and error guidance.
- Updated the dashboard to present these four APIs and their usage in one place.
- New accounts receive 10 non-expiring starter credits for API and MCP use.
August 2026
- Added compact company, people, current-employment, and company-trend workflows designed for multi-company research.
- Moved long-tail raw operations behind progressive discovery so clients retain full catalog access without loading more than one hundred schemas per task.
- Added OAuth offline access for refresh-token capable clients, reducing repeat interactive authorization after the first connection.
- Fixed false duplicate-request errors when separate tasks reuse a JSON-RPC ID.
- Published the expanded Superdata documentation site.
- Documented Codex, Claude Desktop, Cowork, Claude Code, Cursor, and direct MCP setup.
- Documented OAuth and API-key authentication.
- Added typed company, people, contact, and LinkedIn workflows.
- Added interactive, non-billable people, company, job, and company-brief result cards.
- Retained progressive capability discovery, inspection, and execution as the fallback for unfamiliar and newly released operations.
- Corrected tool annotations so read-only research does not request mutation approval.
- Added references for capability contracts, operation-specific pagination, mutation confirmation, credits, usage, and public error codes.
