Agentic AI: Getting spArks
Creating a timestamp uses spArks, the prepaid credits in your spArxx.io account. Checking your balance, listing and retrieving your evidence, and verifying certificates are always free.
New accounts created while connecting an AI start with 0 spArks. You can add some in either of these ways.
Get 50 free spArks with the mobile app
- Install the spArxx.io app on iOS or Android.
- Open it. You'll get 50 free spArks on that device. No email or sign-up needed yet.
- Tap Already have an Account? Link Existing Account (called Restore Purchases in older versions of the app). Enter the same email you used to connect your AI and your password, then tap Link Account (Sign In & Restore in older versions).
Signed up with just an emailed code? Then you don't have a password yet. On the Link Existing Account screen, tap Forgot Password?, follow the email to set one, then come back to the app and link.
The 50 spArks move into your account, and your AI can use them right away. One welcome bonus per device.
Use Link Existing Account, not Claim Account. Claim Account creates a new account with a new email, and the email you connected your AI with is already in use.
Buy spArks
- Sign in at app.sparxx.io with the same email you used to connect your AI. Use your password, or tap Magic Link to get a sign-in link by email.
- Click spArks in the upper-right corner to open the Credit Shop.
- Choose a pack. The spArks are added to your account right away.
You can also buy spArks in the mobile app.
Have a gift card? Redeem it at the bottom of the Credit Shop.
What a timestamp costs
| How it's created | Cost |
|---|---|
| By your AI, through an AI connection | 20 spArks |
| By you, in the spArxx.io web or mobile apps | 25 spArks |
1 spArk = $0.01 USD. Current rates are promotional and may change. Your AI can check the current rate and your balance at any time.
Which connection are you using?
There are two kinds of AI connection, and both reach the same spArxx.io account.
- Full (
/mcp, or/mcp-clifor Claude Code): your AI can create timestamps for you. Before each one, it tells you the cost and asks you to confirm. - Read-only (
/mcp-read-only): your AI can check pricing and your balance, list and retrieve your evidence, and verify certificates, but it can't create timestamps or spend spArks. Create timestamps yourself in the spArxx.io web or mobile apps.
Not sure which one you have? Ask your AI whether it can create spArxx.io timestamps. If you added spArxx.io from a connectors directory, that directory decides which connection you get.
