  When not to use: You need market-wide filtering — use the insider screen; or pre-index history beyond our window.
  Examples: ticker=JEF; ticker=JEF&code=P&limit=50
- [sec_latest_filings](https://answerpool.io/v1/sec/filings/latest): List the newest EDGAR filings market-wide for any form type — accession, filer, time and URL from the SEC live feed, normalized. Use instead of polling and parsing the getcurrent Atom feed. Price $0.005/call.
  When to use: Market-wide "what was just filed" for one form type.
  When not to use: Per-company lists or flagged events — other views are cheaper/richer.
  Examples: form=S-1; form=13F-HR&limit=20
- [sec_market_digest](https://answerpool.io/v1/sec/digest): Rank the day's SEC events by salience — bankruptcies, restatements, cyber incidents, insider clusters and large raises first, with flags and links. Use as the one-call daily filing digest for a research or news agent. Price $0.005/call.
  When to use: Daily/segment digests; pair with the flag glossary.
  When not to use: Per-company or per-portfolio monitoring — use the other views.
  Examples: limit=25; date=2026-08-29&limit=10
- [sec_metrics_catalog](https://answerpool.io/v1/sec/xbrl/metrics): List the metric keys the XBRL views accept — revenue, net income, cash, capex and more, each mapped to its us-gaap tags — free. Use once before calling concept, compare, frame or financials. Free (rate-limited).
  When to use: First call before any XBRL view.
  When not to use: n/a - free reference data.
- [sec_shares_outstanding](https://answerpool.io/v1/sec/xbrl/shares): Get reported common shares outstanding by period for one filer from XBRL — the series behind dilution and per-share math, deduplicated. Use instead of digging share counts out of companyfacts or cover pages. Price $0.02/call.
  When to use: Share-count questions.
  When not to use: Public float — not served yet.
  Examples: ticker=NVDA; cik=0000320193
- [sec_ticker_lookup](https://answerpool.io/v1/sec/ticker): Resolve an SEC CIK to its ticker and registered company name from the SEC's official mapping — the reverse of CIK lookup. Free. Use when a filing gives you a CIK and you need the tradable symbol. Free (rate-limited).
  When to use: You hold a CIK (from any filing) and need ticker and name.
  When not to use: Private filers with no listed security often have no ticker.
  Examples: cik=0000320193
- [sec_transaction_codes](https://answerpool.io/v1/sec/insider/codes): Explain Form 4 transaction codes — P purchase, S sale, A award, F tax withholding, M exercise and the rest. Free. Use once so an insider screen filters on the right codes instead of guessing. Free (rate-limited).
  When to use: Before filtering insider transactions by code or direction.
  When not to use: n/a - free reference data.
- [sec_watchlist_events](https://answerpool.io/v1/sec/watchlist): Get flagged SEC events for up to 25 tickers in one call — 8-K items, insider trades and raises since your cursor, with a next cursor to store. Use instead of running one EDGAR poll per portfolio name. Price $0.02/call.
  When to use: Recurring portfolio monitoring; store next_cursor between calls.
  When not to use: Market-wide screens or a single company — cheaper views exist.
  Examples: tickers=JEF,NVDA,AAPL; tickers=JEF,NVDA&since=2026-08-30T00:00:00Z
- [sec_xbrl_compare](https://answerpool.io/v1/sec/xbrl/compare): Compare one XBRL metric across up to 10 tickers — latest reported value per company, ranked, with period ends and tags. Use instead of N companyfacts downloads and a fiscal-alignment headache. Price $0.05/call.
  When to use: Peer comparisons on one metric.
  When not to use: Whole-market ranking — the frame view covers every filer.
  Examples: tickers=NVDA,AAPL&metric=revenue; tickers=NVDA,AAPL&metric=rnd_expense
- [sec_xbrl_concept](https://answerpool.io/v1/sec/xbrl/concept): Get one as-reported XBRL metric series for a filer — revenue, net income, cash and more, or any us-gaap tag — deduplicated 10-K/10-Q values with periods and source URL. Use instead of downloading companyfacts for one number. Price $0.005/call.
  When to use: One metric, one company.
  When not to use: Full statements — use financials; cross-company — use compare/frame.
  Examples: ticker=NVDA&metric=revenue; cik=0000320193&metric=us-gaap:GrossProfit
- [sec_xbrl_financials](https://answerpool.io/v1/sec/xbrl/financials): Get normalized key financials for one filer — revenue, net income, operating cash flow, assets, liabilities, capex, R&D and shares across eight reported periods. Use instead of downloading and normalizing the companyfacts JSON. Price $0.02/call.
  When to use: Multi-metric fundamentals for one company.
  When not to use: One metric — concept is cheaper; peers — compare/frame.
  Examples: ticker=NVDA; cik=0000320193
- [sec_xbrl_frame](https://answerpool.io/v1/sec/xbrl/frame): Rank every SEC filer on one XBRL metric for one period — top-N values with entity names and the total filer count, from the frames API. Use for whole-market screens without a bulk XBRL pipeline; one MCP incumbent exists for xbrl. Price $0.05/call.
  When to use: Whole-market, single-period metric questions.
  When not to use: Company histories — concept/financials; small peer sets — compare.
  Examples: metric=rnd_expense&period=CY2025Q1; metric=revenue&period=CY2025&limit=20
