Reverse lookup against the same Top 1,000 manager seed window as /filings/13f/by-manager. The result is not the full set of 13F filers holding the ticker — only those within the seeded universe.

​
Endpoint

​
GET
string
https://api.llmquantdata.com/filings/13f/by-ticker

​
Parameters

​
ticker
string
required
U.S. ticker symbol (e.g. NVDA). Case-insensitive; normalized server-side (BRK.B → BRK-B).
​
period
string
Quarter-end date YYYY-MM-DD. Omit for the latest seeded quarter.
​
limit
integer
default:100
Maximum holders to return (max 1000). Use higher limits if the consumer wants the full Top 1000 holder list and will trim by manager AUM proxy client-side.

​
Response

​

Caching

  • Backed by the local canonical.sec_13f_holdings index used for the manager-direction route.
  • Permanent cache (seed-only, no upstream refresh).
  • Cache misses (ticker absent from every Top 1000 manager’s seeded quarters) return empty holders + meta.scope_notice.

Current Limitations

  • Top 1,000 manager scope only — not full-market ownership
  • No aggregate ranking (e.g. “this quarter’s top net buys”)
  • No long-tail managers
  • No confidential holdings
