Self-serve financial intelligence

Evaluate free. Then keep the watch running.

Follow pages stay free. A monthly plan buys the Build layer: API, MCP, provenance, an included credit allowance, and alerts that tell you what changed on the names you follow.

Application Builder

Building a customer-facing app on Arkolith outputs is a free opt-in permission, not a separate tier and not a higher price. Accept the builder terms in billing on any plan, and your app draws down the same monthly credit allowance you already have. No raw resale, no competing data feed, and source restrictions still apply.

How the credit allowance works

Most calls cost 1 credit. A capital-change brief costs 10, and the heavier joins and point-in-time tools cost more. Your plan includes a monthly allowance that refreshes on your billing date and does not roll over.

Every plan gets the full toolset

Paid plans do not unlock hidden datasets. They buy three things the code actually enforces: how much you can run, how fast Form 4 filings reach you, and whether we email you what changed.

Frequently Asked Questions

What data is included?

13F institutional holdings, ownership changes, Form 4 insider activity, and sourced filing links, for tickers and funds resolvable in Arkolith's tracked SEC corpus. The product is built around clean identifiers, point-in-time access, and provenance.

What happens when I use up my monthly credits?

Calls stop until your allowance refreshes on your next billing date. If you are regularly running out, move up a plan. We are shipping a usage warning and a small buffer so a long agent run does not stall on its last call.

What exactly do paid plans unlock?

Three things, all enforced in the code. Volume: 5,000, 25,000, or 75,000 included credits a month. Delivery: from Starter, your watchlist emails you what changed instead of waiting for you to ask. Freshness: from Developer, watchlist.poll.live returns Form 4 filings within minutes of SEC acceptance, while Evaluation and Starter poll at standard freshness, which excludes the last 24 hours. The datasets are identical on every plan.

How do I start a paid plan?

Start the $1, 3-day trial: full Starter access for three days, then pick a plan from Billing in the console. Your API key does not change, any unused evaluation credits stay in your balance, and the plan's monthly allowance starts immediately.

Can my agent set up its own watchlist?

Yes. watchlist.add, watchlist.remove, and watchlist.list are MCP tools and they cost no credits. Your agent can arm a watch in the middle of a conversation, right after it answers a question about a name, and the watch shows up in your console.

What is MCP?

Model Context Protocol lets Claude, Codex, and other agents call Arkolith as a tool. The same data is also available through REST.

Can I build an app on top of Arkolith?

Yes, if you opt in to Application Builder terms. You can build customer-facing workflows on outputs, but not resell the raw data or create a competing feed.
