Plans and limits
Lumin has two plans, and every one of the 158 tools is on both. Everyone starts free with 300 tool calls a month. A complete reading uses 25 to 40 calls, so the free allowance covers roughly 7 to 12 complete readings a month.
| Plan | Price | Included | Scope |
|---|---|---|---|
| Free | $0 | 300 tool calls / month | Per signed-in account or API key |
| Pay as you go | From $10 | Prepaid call packs, calls never expire | Tops up the same meter |
How to read these numbers
A complete KP reading using the seven-phase protocol uses 25 to 40 tool calls. A quick chart pull uses 1 to 5. A casual conversation with follow-up questions sits between, around 10 to 15 calls per question. In readings, the free plan works out to roughly 7 to 12 complete readings a month, or a couple of readings a week with follow-ups to spare.
No tool is gated behind payment. The plans differ only in how many calls you have, never in what you can ask.
How the meter works
The meter is monthly and counts only tool calls that actually run. A failed call, whether a validation error, an auth problem, or a server fault, does not count. Setup traffic like connecting and listing tools is never counted either.
The allowance refreshes on the 1st of each month, UTC. It is metered per credential: your signed-in account when you connect through Claude, or the API key when you use one. There is no daily cap, so you can run a whole month of readings in one weekend if you like.
Pay as you go
When you need more than the free allowance, you buy a prepaid call pack. There is no subscription, the calls never expire, and one call is one call, no weighted credits.
| Pack | Calls |
|---|---|
| $10 | 5,000 calls |
| $25 | 15,000 calls |
| $50 | 35,000 calls |
| $100 | 100,000 calls |
