Lifetime, on-chain.

You pay once with Bitcoin. Pick a tier, send the on-chain payment to the address shown at checkout, and your plan activates automatically after the first network confirmation. There’s no billing account, no card on file, and no recurring charge.

No. Every paid tier is a one-time payment for lifetime access. There’s no auto-renew, no monthly fee, and nothing to cancel — you pay once and keep the tier for good.

Your payment is verified on-chain via mempool.space. As soon as the first confirmation lands, your plan activates instantly and your API key is unlocked. Activation usually takes a few minutes, depending on network conditions.

Payment settles and is verified directly on the Bitcoin blockchain — we never touch a card or bank detail, and there’s no KYC. You can independently confirm the transaction on mempool.space using the address and amount shown at checkout.

No. Access is a digital good delivered immediately on confirmation, so payments are non-refundable. If activation goes wrong, reach out via the contact page and we’ll sort it out.

Current pricing is founding-member pricing and may rise as the product matures. The tier you buy is locked for life at the price you paid — lifetime access is never re-priced after purchase.

If you underpay, the plan will not activate automatically — reach out via the contact page with your transaction hash and we will reconcile it. If you overpay, contact us and we will credit or refund the difference. Every payment is verifiable on-chain via mempool.space using the address and amount shown at checkout.

Yes. Tiers are strict upgrades, so you only ever pay the difference in value by purchasing the higher tier — you are never charged twice for what you already hold, and you cannot accidentally buy a tier below the one you own. Start on Free or Pro and move up whenever you need fresher data or a higher daily limit.
