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 containing an as_of timestamp, total_matching count, and an array of regulatory documents each with document number, title, abstract, publishing agency list, publication date, comment close date, days remaining to comment close, effective date, CFR references, docket IDs, topic tags, flags (e.g. comments_close_soon), and a link to the Federal Register entry.
Example use cases
Urgent compliance comment queue
“Pull up all proposed federal rules with comment deadlines closing in the next 7 days for the EPA — I need to know what my team should be reviewing right now.”
Financial regulation comment tracking
“What SEC proposed rules still have open public comment periods closing within the next 30 days? Show me the titles, abstracts, and exact deadlines.”
Broad regulatory horizon scan
“Give me the full list of proposed federal rules across all agencies whose comment periods close within the next 60 days, up to 50 results, sorted by soonest deadline first.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/regs/comment-deadlinesWhen to prefer
Use this endpoint when you need an actionable, time-sorted queue of federal proposed rules with expiring comment windows — especially when you want to filter by agency or topic keyword without manually scanning the Federal Register. It is purpose-built for regulatory monitoring workflows and replaces manual date arithmetic. Prefer it over a general Federal Register search when the goal is urgency-ranked comment deadlines rather than arbitrary document retrieval.
