Get Index Fund and ETF Holdings by Fund Ticker or Holding Ticker (Financial Datasets)
Get the holdings of an index fund or ETF by the fund's ticker, or find which index funds hold a given stock by passing holding (at least one of ticker or holding). Optionally set as_of for a past date and asset_class to equity or bond. Each row pairs one fund with one holding and its position as of that date. Up to 100 holdings per page, paged with offset or 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 /index-funds on Glasser with input {"limit":1,"ticker":"SPY"}glasser run -p financialdatasets -e '/index-funds' -i '{"limit":1,"ticker":"SPY"}' --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":"/index-funds","input":{"limit":1,"ticker":"SPY"},"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.
