This is deliberately NOT full parity. Financial Datasets returns 21,005 distinct CIKs here (measured 2026-09-04) because it also covers filers with no listed ticker; this server returns the 8,005 it can actually source, every one of which is present in Financial Datasets' list too. Fetched through Monid's context.dev scraper, and cached, for the same reasons as /filings/ciks. ## OpenAPI ````yaml /api-reference/openapi.json get /company/facts/ciks openapi: 3.1.0 info: title: Monid Finance API version: 1.0.0 summary: A Financial Datasets-compatible finance REST API backed by Monid providers. description: >- US equities fundamentals, prices, filings, news, insider trades, and a stock screener, generated faithfully from this repository's Go source (go/httpapi/rest.go, go/service, go/fd). This server is drop-in compatible with the Financial Datasets REST and MCP interface: the same route shapes, the same query parameters, and response objects whose field names and field order match the Financial Datasets contract, captured 2026-09-04. It is an independent, Monid-backed implementation; it is not affiliated with or endorsed by Financial Datasets, and no Financial Datasets data or outputs are used. **Bring your own Monid API key.** Every request carries the caller's own key in the `X-API-KEY` header. Usage bills that caller's own Monid wallet; this server never stores or logs the key. Get a key at https://monid.ai. **Coverage.** All 54 Financial Datasets REST paths are registered. all 54 return data; most call live Monid providers, and a handful (the static catalogs and the accept-universe coverage lists; see each operation's description) never call Monid at all. Every registered path answers from a live source; there are no not_implemented stubs. /kpi/metrics/sectors returns the screener provider's own industry taxonomy and /index-funds/tickers the upstream fund universe, both scraped through Monid on demand. See docs/compatibility.md for every deliberate deviation and docs/openapi-notes.md for how this document was derived. **Errors and soft failures.** Every failure — real HTTP error and zero-cost soft failure alike — uses the two-key body `{"error": , "message": }`. Some routes answer `not_found` with HTTP 200 rather than a 4xx status (see each operation's description). **Pagination.** List routes return a wrapped envelope (e.g. `{"income_statements": [...], "next_page_url": "..."}`) with opaque, server-minted base64url `cursor` tokens. Pages hold 10 records (100 for /prices). `next_page_url` is an absolute URL on this deployment's own host, present only when more records remain. **Ticker coverage lists are accept-universes, not data-coverage claims.** The eight `*/tickers` routes (e.g. /company/facts/tickers, /kpi/metrics/tickers) all answer from the same ~3,227-ticker US equity catalog: the tickers a route will ACCEPT as input, never a promise that every one of them has data for that particular dataset - this server has not measured per-dataset coverage. Their own `limit` (default 1000, max 5000) and `cursor` query parameters page through that shared universe independently of every other route's pagination convention above. contact: url: https://docs.financialdatasets.rip license: name: MIT identifier: MIT servers: - url: https://financialdatasets.rip description: Production (Fly.io). security: - ApiKeyAuth: [] tags: - name: Financial statements description: Income statements, balance sheets, cash flow statements. - name: Financial metrics description: Historical financial metrics and the live snapshot. - name: Earnings description: Earnings records composed from SEC filing events. - name: Filings description: SEC filing index and extracted filing sections. - name: Prices description: Historical OHLCV prices and the live price snapshot. - name: News description: Ticker-matched news. - name: Insider trades description: SEC Form 4 insider trading transactions. - name: Screener description: Stock screener and its executable filter catalog. - name: Company description: Company facts. - name: KPIs description: >- KPI-taxonomy metrics, forward guidance, and non-GAAP metrics extracted from SEC filings. - name: Macroeconomics description: Central bank policy interest rates. - name: Index funds description: ETF / index-fund holdings. - name: Institutional holdings description: SEC Form 13F institutional-holdings rows. - name: Ownership description: Insider, beneficial (13D/13G) and activist ownership state. - name: Not implemented description: >- Routes registered for Financial Datasets route parity; always a zero-cost not_implemented stub today. paths: /company/facts/ciks: get: tags: - Company summary: Available CIKs for company facts description: >- The CIK universe this server can resolve company facts for: SEC's company-ticker file, deduplicated, zero-padded to 10 digits, sorted ascending.
