1,050,000 filing events and counting: live SEC Form 4 insider transactions, normalized within minutes of SEC acceptance (8-K and Schedule 13D/G are on the roadmap). Your agent polls a cursor on the tickers it watches and never misses a filing; every event carries its accession number and source URL.
Straight off this API (events.latest / watchlist.poll.live), what your agent would see right now.
What a live EDGAR pipeline actually takes to acquire and keep clean
| The trapped part | DIY from the source | With Arkolith |
|---|---|---|
| Polling the index | EDGAR's full-text index updates on its own schedule; staying minute-fresh means polling, rate limits, and retry plumbing. | We run the poller. watchlist.poll.live serves filings within minutes of SEC acceptance. |
| The form-type zoo | Every form type has its own document structure; normalizing filer vs subject vs ticker is per-form work. | One normalized event shape (filer, subject, tickers resolved), done for Form 4 today; 8-K and 13D/G land on the same shape as we expand the stream. |
| Exactly-once | At-least-once feeds mean duplicate accessions unless you build dedupe and a stable cursor yourself. | Accession-deduped with a monotonic cursor: agents resume exactly where they left off. |
| From event to meaning | A raw Form 4 event still needs joining to holdings, prior insider history, and prices to mean anything. | The same key queries 13F books, Form 4 line items and cross-source signals on the name. |
Live from the MCP catalog, also available as REST endpoints
search1 crResolve a name to a tracked entity. Turn a fund or manager name (e.g. 'Berkshire', 'Citadel') into the SEC CIK or slug you pass to the fund.* tools — the entity-resolution entry point. Searches funds and managers by name or identifier.
events.latest1 crLive SEC filing-event stream: SEC Form 4 (insider) filings today, with 8-K and 13D/G on the roadmap. Poll with `since` (a monotonic cursor) to get every filing newer than your last call; the response's next_cursor advances it. Filter by form or tickers; a form we don't carry yet returns an explicit unsupported_form note (never a silent empty page). Built for a watch loop, so call it on a schedule to never miss a filing.
watchlist.poll1 crPoll THIS workspace's watchlist for new filings since a cursor: every SEC Form 4 (insider) filing on the tickers your team follows, newest-after-cursor (8-K + 13D/G are on the roadmap). Pass `since` (a prior next_cursor) to get only what's new; built for a watch loop. Curate the watchlist in the Arkolith dashboard. Standard (delayed, ≤24h-old) freshness; each event carries its SEC source URL.
watchlist.poll.live3 crLike watchlist.poll but LIVE freshness — includes filings accepted within the last 24h (minute-fresh, normalized within minutes of SEC acceptance). Premium-priced and requires the Developer or Pro plan; other plans poll delayed (≤24h-old) freshness via watchlist.poll. Same workspace-watchlist scope and cursor semantics.
provenance.get1 crTrust layer: return the source record(s) for a datapoint — origin URL, fetch time, parser version — so the agent can cite primary sources.
provenance.get: anti-hallucination grounding for agents
Any figure your agent quotes can be traced to the primary source: the origin URL, the fetch timestamp, and the parser version that produced it. Your agent cites the filing. It doesn't hallucinate one. That audit trail is first-class on every tool, REST and MCP.
