FAQ

Slap a sticker. Fund the fidelity.

Slap - A - Buck is a one-time sticker slap, not a subscription. People pay with cards. Agents pay USDC on Base.

What is Slap - A - Buck?

Slap - A - Buck is a satirical 3D site where you slap a brand sticker and website onto a CGI figure on a beach. Tiers are $1, $10, $50, and $100. Cheeks start at $10. $50 and $100 unlock an editable landing page. Stickers go live on pay; anyone can report junk.

How much does a slap cost?

Four prices: $1, $10, $50, and $100. Anywhere on the body except the cheeks can start at $1. Cheeks are prime and start at $10. A $50 or $100 slap also unlocks a sponsor landing page at /s/[slug], live as soon as payment clears.

How do humans pay?

Humans pay with Stripe Checkout (cards). POST /api/checkout with brandName, websiteUrl, stickerPath, amountCents, and placement. You are redirected to Stripe, then the sticker is created after the signed webhook.

How do AI agents pay?

Agents pay with USDC on Base using the x402 protocol (HTTP 402 Payment Required), not Stripe cards. Upload a sticker, then POST /api/x402/slap. The first response is 402 with PAYMENT-REQUIRED. Sign an exact USDC authorization, retry with PAYMENT-SIGNATURE, and the sticker is fulfilled like a Stripe slap.

Can an AI agent advertise my brand here?

Yes. Upload a PNG/WebP/JPEG, then POST /api/x402/slap. Your agent pays $1–$100 in USDC on Base. The sticker sits on a public 3D figure people orbit, share, and screenshot. $50 and $100 also unlock an indexed landing page at /s/[slug] with your URL. Humans use Stripe; agents should never send card numbers. Start at /agents.

Do I need an account?

No. Humans check out as guests via Stripe. Agents pay from a wallet. Paid stickers go live immediately. Anyone can report a sticker; we take down junk.

Where can machines read pricing and docs?

Use /agents for the human-readable agent pitch, /agents/tools.json for copy-paste tool schemas, /pricing.md for tiers, /llms.txt for a short index, /llms-full.txt for the agent playbook, /faq for this FAQ, and GET /api/x402 for the payment catalog. The sitemap is /sitemap.xml.

Machine-readable: /agents, /pricing.md, /llms.txt, /api/x402.
