Use structured filings, financial statements, ownership records, economic events, and supported on-chain metrics across research, screening, monitoring, and product applications.
Build company screens, compare reported financial concepts, analyze accounting ratios, and combine issuer metadata with market and historical data.
Retrieve clean 10-K and 10-Q sections, monitor 8-K events, compare Risk Factors across years, and provide structured filing text to search, NLP, or LLM workflows.
Track insider purchases and sales, institutional holdings, beneficial-ownership filings, proxy statements, earnings releases, and other corporate disclosures.
Place company fundamentals alongside economic-event schedules, market prices, DEX liquidity, and verified on-chain metrics in research platforms and internal dashboards.
The Fundamentals API includes company discovery and profiles, SEC filing metadata, filing text and Risk Factors analysis, XBRL financial statements, accounting ratios, cross-sectional screens, insider transactions, institutional holdings, upcoming US economic events, and verified on-chain datasets where supported.
No. Public-company fundamentals are a major part of the product. SiftingIO provides structured SEC filings, XBRL financials, filing-derived text, insider transactions, institutional holdings, and issuer metadata in addition to supported on-chain and macro datasets.
The documented filing endpoints cover 10-K, 10-Q, 8-K, DEF 14A, Schedule 13D and 13G, and earnings-release filings. Filing metadata includes accession numbers, filing dates, reporting periods, document links, and XBRL availability where applicable.
Yes. Filing-text endpoints extract standard 10-K and 10-Q sections from the primary HTML document into clean text. Extraction is best-effort because SEC filing markup varies by issuer and filing.
It compares the latest annual 10-K Risk Factors section with the prior year and groups paragraph-level changes into added, removed, and modified disclosures.
You can retrieve a company's complete reported XBRL bundle, request one concept across every reported period, compare one concept across filers for a selected SEC calendar period, and query accounting ratios derived from reported statements.
Not in the current version. The ratios endpoint is derived from reported XBRL concepts and currently excludes stock-price-dependent valuation ratios such as P/E, P/B, and EV/EBITDA.
Yes. Insider endpoints normalize Form 3, 4, and 5 transactions into row-level records. The institutional-holdings endpoint returns the latest 13F-HR positions for supported filers.
It provides upcoming US economic events such as CPI, NFP, FOMC, and GDP, with official UTC schedule times, impact tiers, affected currency, and issuing-agency metadata. Some release-result fields may remain null until the corresponding release-data pipeline is available.
On-chain availability depends on the currently enabled metric, network, protocol, and entitlement. The page and documentation should list only verified metrics. Pair-level DEX TVL should not be interpreted as proof of protocol-wide supply, holder, fee, or revenue coverage.
Company fundamentals, filing data, XBRL, ownership records, economic events, and current on-chain snapshots are REST datasets. WebSocket is used separately for supported live market-data streams.
Send the SiftingIO API key in the X-API-Key header for REST requests. The same account and API-key system is used across entitled SiftingIO products.
Company fundamentals are currently associated with the US Stocks product unless the active entitlement configuration specifies otherwise. On-chain datasets may use a different entitlement or custom access path.
Usage rights depend on the dataset, plan, and use case. Customer-facing display, bulk extraction, B2B redistribution, sublicensing, or embedded commercial use may require an eligible paid plan or Enterprise agreement.
A Free account can be used to evaluate eligible endpoints without a credit card. Exact dataset access, history, limits, and entitlements depend on the product associated with the endpoint.
