URL to Markdown API without a crypto wallet
Yes — humans buy 200 reads for $2 on Stripe. No wallet, no subscription, and only accepted reads spend a credit.
Pay once on Stripe Checkout
Stripe hosts the checkout page itself. You pay $2.00 USD one time. There are no recurring charges at all. No crypto wallet is created or linked.
Keep your credit token
Stripe verifies your payment first. Then you receive a reusable credit token. The token ties to your paid Checkout session. Send it in the X-SML-READER-CARD header. Each accepted read costs exactly one credit.
Only success spends a credit
A valid Markdown response spends one credit. Failed reads spend no credits at all. Blocked sources spend no credits either. Private or oversized pages are refused without charge.
What a real job showed?
ScriptMasterLabs measured eight public documentation pages on October 28, 2026. Returned Markdown was 95.3 percent smaller than raw HTML. The reads returned 129,881 characters of Markdown. The same pages carried 2,773,841 bytes of HTML. Two attempted pages were refused with no charge.
Same reader, two ways to pay
Most x402 readers require a funded wallet first. This card pack removes that step entirely. Both payment paths use the same reader. Agents pay 0.001 USDC per accepted read. Humans pay $2 once for 200 reads. The Markdown output is identical either way. SML does the same job without any wallet setup.
Who should still use a wallet?
Agents reading at volume pay less per read. The 10-read agent pack costs 0.005 USDC. Humans and small teams fit the card pack. No exchange account is needed for cards.
Start with the free preview
The free preview needs no key or wallet. It runs one fixed public page free. Check the output shape before you pay. Then check the card pack and live price when you are ready.
