Credits & pricing
Usage is metered in prepaid credits. One credit = $0.01. Cheap reads drive adoption; the resolution, point-in-time, and cross-source join patterns are the moat, so they cost more.
How metering works#
- · Discovery is free. Listing tools, reading the catalog, and checking your balance never cost credits.
- · You spend on the answer. A successful
tools/call(or REST data request) debits that tool's weight. - · Failures are refunded. A 500 is never billed, and several tools return a no-charge result when a valid query yields nothing billable. See Errors.
- · The $1 trial. Every new workspace starts with a three-day trial with 300 research credits, so you can run real multi-tool research loops before a plan starts. It becomes $29/mo on Starter after day 3 unless you cancel. Arkolith is a paid product: sustained usage means a monthly plan.
What each tool costs#

Monthly plans#
The $1 trial is three days of Starter; after that Starter continues at $29/mo unless you cancel from Billing first. Each plan includes a credit allowance that refreshes on your billing date and does not roll over. Paid plans do not unlock hidden datasets: they buy volume, how fast Form 4 filings reach you, and whether we email you what changed on the names you watch.
| Plan | Per month | Included credits | Briefs |
|---|---|---|---|
| Starter | $0 | 5,000 | about 500 |
| Developer | $1 | 25,000 | about 2,500 |
| Pro | $1 | 75,000 | about 7,500 |
Briefs are the heaviest common call at 10 credits, so that column is the pessimistic read of a month. Most lookups cost 1.
Why metered, not seat-based
Your agent calls our MCP server directly. We never run inference. You pay for data, not for someone else's model tokens, so a deep research loop costs cents.
