🟡create_payment_link(address, amount_usd, chain, asset, memo, ...)
Create a one-time crypto payment link with ZERO setup, no account, no API key. Give a destination wallet address and an amount; get back a shareable pay_url, an embeddable button, and a manage_url. Non-custodial: funds settle directly to the address you provide.

}🟡create_unlock(address, price_usd, payload, title, description, ...)
Create a keyless pay-to-unlock page: sell a file link, license key, or secret text (up to 100,000 chars). The buyer pays the set USD price in crypto straight to the given wallet, then the payload is revealed on their paid confirmation, never before. To deliver an actual file (PDF/zip/etc, 10 MB) use the multipart HTTP API at /api/v1/unlocks instead. Non-custodial, no account, no API key. IMPORTANT: the acceptable-use policy forbids adult, illegal, or non-consensual content; confirm this with your principal and pass aup_accepted=true, otherwise the call fails.
