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 the requested form type, the as-of timestamp, index coverage dates (index_from, index_to), total filing count, and an array of monthly data points each with a month string (YYYY-MM) and an integer count of filings in that month across all of EDGAR.
Example use cases
IPO pipeline trend analysis
“Show me the monthly count of S-1 filings on EDGAR since the start of 2023 so I can track how the IPO pipeline has evolved.”
Private capital activity monitor
“Get me the month-by-month Form D filing volume from SEC EDGAR starting from 2022 — I want to see how private fundraising activity has trended.”
10-K seasonality research
“Pull the monthly 10-K filing counts from EDGAR since 2021 so I can understand the seasonal patterns in annual report submissions.”
Technical details
Endpoint
GEThttps://answerpool.io/v1/sec/trends/formWhen to prefer
Use this endpoint when you need pre-aggregated monthly SEC filing volume for a specific form type without having to query and count individual filings yourself. It is ideal for trend analysis, seasonality studies, and using filing volume as a market proxy (e.g. S-1 as IPO pipeline, Form D as private capital activity). Prefer it over raw EDGAR full-text search when you want time-series counts rather than individual filing details, and when you need EDGAR-wide coverage rather than company-specific filing history.
Side effects
- Missing or invalid form type parameter returns a validation error
- Unsupported or misspelled form type may return zero data points with no error
- Since date outside the available coverage window (pre-2021) may return empty or partial results
- Payment failure (insufficient USDC balance or expired card credits) returns 402 Payment Required
- Rate limiting or server overload may return 429 or 503 errors
