Available CIKs for SEC filings
Every CIK in SEC EDGAR’s published company-ticker file, in SEC’s own row order and unpadded. Verified byte-identical to Financial Datasets’ live /filings/ciks response on 2026-09-04: same 10,412 entries, same order, same formatting. Duplicates are intentional - a company with several share classes appears once per ticker, exactly as it does upstream. Sourced free from SEC, so this route makes no Monid call and costs nothing. The file is fetched through Monid’s context.dev scraper rather than by a direct HTTP call, so the request is billed to the caller’s wallet, writes a receipts-ledger entry and is checked against the discovery allowlist like every other upstream call. Measured cost $0.0009, cached for six hours.
Authorizations
The caller's own Monid API key (get one at https://monid.ai?fpr=dhruv-15136b). Passed straight through to Monid on every call, so usage bills the caller's own wallet — this is never a shared server-side credential, and the server never logs or stores it. Missing, empty, or malformed values answer 401 unauthorized before any paid call is attempted.
Response
CIK enumeration.
A CIK enumeration: {"resource", "ciks"}. Sourced from SEC EDGAR's free company_tickers.json, never from a paid provider, so these routes cost the caller nothing (see go/service/secciks.go). Returned whole, with no pagination, matching Financial Datasets' own behaviour.
