Pricing
Pay for receipts, not infrastructure.
Usage-based, priced on the one unit that matters — a signed receipt. Anchoring is batched, so your cost per receipt stays flat whether you send a hundred a day or a hundred million.
Everything is free during early access. The tiers below are where pricing is headed — illustrative and subject to change, not a bill you’ll get today. No card required to start.

How pricing works
One metric. Flat cost as you scale.
You pay per receipt
Every logged AI action returns one signed receipt — that’s the unit you pay for. No seats, no per-endpoint surprises, no charge for reads.
Anchoring is batched
Receipts settle to the blockchain in a single daily transaction — one batch can carry thousands. Because the expensive part is one shared transaction, your per-receipt cost doesn’t climb with volume.
Verifying is always free
The public verifier and offline signature check never touch your plan. Proving a receipt is real costs nothing and needs no account.
Start free. Upgrade when you scale.
