Search 13F Institutional Holdings by Manager CIK or Report Period (SEC API)
Search Form 13F filings of institutional investment managers and funds with a Lucene-style query over named fields such as cik (the manager's CIK), periodOfReport and filedAt (for example cik:1067983). Each row is one 13F filing with every holding the fund reported: CUSIP, number of shares and market value per position. Rows can be large, so the default page is 10 filings; up to 50 per page with a from offset, sorted by filedAt.

}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 SEC API Endpoint /form-13f/holdings on Glasser with input {"size":2,"query":"cik:1067983"}glasser run -p secapi -e '/form-13f/holdings' -i '{"size":2,"query":"cik:1067983"}' --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":"secapi","endpoint":"/form-13f/holdings","input":{"size":2,"query":"cik:1067983"},"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.
