What It Is

Last10K is a site focused on SEC disclosure filings for U.S.-listed companies. Its page title highlights “Company SEC Filings for 10-K Annual Reports and 10-Q Quarterly Reports,” and it also offers an “SEC Filings API.” Judging by the navigation, it covers not only 10-K annual reports and 10-Q quarterly reports, but also stock screening, earnings, trends, insider transactions, manager holdings, sentiment analysis, Late NT, Footnoted, and other sections. Overall, it is positioned more as a financial research and data analysis tool than a traditional marketing or SEO platform.

Core Features and Data

Based on the crawled text, its confirmed core value is the ability to search and access SEC Filings via API, especially 10-K and 10-Q filings. This can be useful for investment research, financial statement analysis, compliance monitoring, and tracking information on public companies. It is worth noting that the text does not disclose the number of companies covered, historical data depth, update frequency, field structure, API limits, or data quality details, making it difficult to assess the scale and stability of its dataset.

Pricing, Platform, and Integrations

The available text does not mention pricing, plans, free trials, or payment methods. In terms of support channels, only links such as About, Contact, Help, API, Privacy, and Terms are visible, indicating that the site at least provides help and contact pages, but it does not specify SLA, ticket support, email support, or live chat. For integrations, the SEC Filings API is the clear highlight, but there is no description of authentication methods, examples, SDKs, Webhooks, or third-party platform integrations.

Pros and Cons

Its strengths are clear positioning around SEC filings and public company disclosure data, plus the availability of an API, making it suitable for embedding financial disclosure data into internal investment research, risk control, or analytics systems. The multiple financial analysis sections in the navigation also suggest it may support broader research use cases. The downside is the limited publicly available information, especially around pricing, trials, data coverage, rate limits, and support commitments, so further verification is needed before procurement.

Best Fit and Access from China

Last10K is better suited to financial data teams, investment research analysts, compliance teams, quant teams, and data engineering teams, rather than as a general SEO or marketing tool. Access from mainland China cannot be determined from the available text alone, and API stability and payment availability are also unknown. If access or procurement is limited, alternatives worth comparing include SEC EDGAR, BamSEC, AlphaSense, Intrinio, and Financial Modeling Prep.
