Billing and call packs
Lumin billing is deliberately simple. The free plan costs nothing and never asks for a card. When you need more calls, you buy a prepaid pack, and that is the entire model.
The free plan
Every account starts on the free plan: 300 tool calls a month, all 158 tools, refreshed on the 1st of each month, UTC. No card is ever required, there is no trial that expires, and there is nothing to cancel. If you stop using Lumin, nothing happens and nothing is charged.
Call packs
When the monthly allowance is not enough, you top up with a prepaid call pack:
- $10 for 5,000 calls
- $25 for 15,000 calls
- $50 for 35,000 calls
- $100 for 100,000 calls
Packs are not a subscription. You pay once, the calls sit on your account, and they never expire. One call is one call, every tool costs the same, and there are no weighted credits to decode.
How to buy
Packs are bought by email while card checkout is on the way. The flow is three steps:
- Write to contact@lumin.guru from the email address you sign in with, naming the pack you want.
- We reply with payment details for a direct transfer.
- Once the payment lands, the calls are credited to your account, usually the same day. You can see the balance on the Developer page at app.lumin.guru/developer.
Pack calls are spent only after the month's free allowance is used, and a failed call is never charged, the same rule the free allowance follows.
Custom volume
If you are building a product or business on Lumin and packs do not fit your volume, custom limits are available. Email contact@lumin.guru with a sentence about what you are building and the volume you expect.
