Technical details
Endpoint
GEThttps://filingspulse.theaslangroupllc.com/api/filings/ownership?utm_source=zero.xyzWhen to prefer
Use this endpoint when an investing or equity research agent needs to understand who owns a US-listed stock, track institutional buying/selling trends, identify activist or hedge-fund involvement, or monitor smart-money positioning shifts quarter over quarter. Prefer this over general financial data APIs when the specific need is EDGAR-sourced 13F/SC 13D ownership intelligence with fund-flow analysis.

- Unknown or delisted ticker returns no data or 404
- Non-US-listed company ticker not supported
- Very recent quarter data not yet available if 13F deadline not passed
- Rate limiting or payment failure returns 402 or 429
- Malformed ticker symbol returns validation error
