How this service works
AnswerPool turns SEC EDGAR, the Federal Register, USAspending, NIH, BLS and OpenAlex into structured JSON answers that AI agents and developers fetch in one call. 69 endpoints free, no account; derived analyses $0.02–$0.05 per call by card credits or USDC (x402). MCP server, full provenance.
Output
A JSON object with an as_of timestamp, total matching count, and an array of regulatory documents each containing document number, title, rule type, action description, publishing agencies, publication date, effective date, comment close date, significance flag, abstract, docket IDs, CFR references, topics, a Federal Register URL, deadline flags (e.g. 'significant', 'effective_soon', 'comment_closing_soon'), and integer countdowns for days to effective and days to comment close.
Example use cases
SEC registrant compliance monitoring
“Show me all final rules and proposed rules that have been published in the last 90 days affecting 17 CFR 240, and flag any that are effective soon or have open comment periods.”
Environmental rule deadline tracking
“Get me the newest federal rules and proposed rules touching 40 CFR 112 — I need to know which ones have comment deadlines coming up and how many days I have left.”
Banking regulation change alerts
“Fetch the most recent 50 regulatory documents amending 12 CFR 1026, both final rules and proposed rules, going back to January 1 2025, and highlight anything marked significant.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/regs/cfrWhen to prefer
Choose this endpoint when you need to track regulatory changes at the granular CFR title and part level rather than by agency or broad topic. It is ideal for compliance teams, legal counsel, or AI agents that need to monitor exactly the provisions a regulated entity is subject to — for example, all rules touching 17 CFR 240 for broker-dealers — with built-in deadline countdown flags eliminating manual calendar tracking.
