Get 13F Institutional Holdings by Stock Ticker or Investor CIK (Financial Datasets)
Get 13F institutional holdings two ways: by ticker for the institutional investors that hold a stock, or by filer_cik for the positions one investment manager holds. Supply ticker or filer_cik (at least one), and narrow by report_period or a report period range. Each holding returns the investor, the ticker, the report period, shares held and market value. Up to 100 holdings per page with a cursor.

}This Endpoint publishes no output schema. You get the Provider's own response body, unchanged — we do not warrant a shape we cannot guarantee.
How to run it
Two fields identify it: the Provider and the endpoint key. The key looks like a path because it usually mirrors the Provider's own, but it is an opaque identifier — not a URL you can open. The same provider:endpoint pair is what your Policy lists.
Once: paste this into your agent's chat. The Skill installs the CLI and logs in by itself. For an agent that cannot use a shell, connect it over MCP instead.
set up https://glasser.ai/SKILL.mdThen ask for this Endpoint:
Run the Financial Datasets Endpoint /institutional-holdings on Glasser with input {"limit":1,"ticker":"AAPL"}glasser run -p financialdatasets -e '/institutional-holdings' -i '{"limit":1,"ticker":"AAPL"}' --endpoint-version 1Pinned to version 1, the one this page shows: if a newer version is published first, the Run is refused instead of charged under new terms. Install and log in first on Get Started.
Once per Run:
IDEMPOTENCY_KEY=$(uuidgen)Run it, and copy this same block to send it again:
curl -X POST https://api.glasser.ai/v1/runs \
-H "Authorization: Bearer gl_..." \
-H "Idempotency-Key: $IDEMPOTENCY_KEY" \
-H "Content-Type: application/json" \
-d '{"provider":"financialdatasets","endpoint":"/institutional-holdings","input":{"limit":1,"ticker":"AAPL"},"endpoint_version":1}'Reuse the same Idempotency-Key to send it again: the second send is a read of the first Run. A new key is a new Run and a new Charge. Pinned to version 1 for the same reason as the CLI.
