A SEC-API.io alternative for research-ready financial data
SEC API is specialized EDGAR infrastructure with broad form coverage and fast filing delivery. Equibles narrows the problem to US-listed investment research, then joins filings to financials, ownership, trading activity and earnings intelligence. [1] [2] [4] [6]

Quick verdict
The short answer
Choose SEC API when exhaustive EDGAR coverage, raw filing infrastructure and low-latency delivery are the product. Choose Equibles when your end goal is cited company research across SEC documents and other investment datasets, delivered through MCP, REST and a research interface. [1] [2] [4] [6]

Beyond the checklist
Infrastructure breadth versus research depth
SEC API exposes a large slice of EDGAR as developer infrastructure: filings and attachments back to 1993, hundreds of form types and fast new-filing delivery. Equibles deliberately serves a smaller research universe—US-listed companies—but adds normalized documents, cited search, extracted analysis, financial statements and non-SEC datasets. The right choice depends on whether your application sells SEC infrastructure or uses SEC evidence to answer investment questions. [1] [2] [4] [6]
Bottom line
Who should choose Equibles instead?
Choose Equibles when your application would otherwise need to combine a filing API with separate fundamentals, institutional holdings, insider trades, short data and earnings-call sources. Stay with SEC API when obscure form coverage, all EDGAR filers, attachment-level access or ingestion latency is the central requirement. Both products now expose MCP capabilities, so MCP alone is not a differentiator. [1] [2] [4] [6]
