Pay Button SDK

Embed stablecoin checkout wherever you already ship code

The Pay Button SDK is the geek path: drop it on a billing page, landing, bot, or internal tool. Customers pay USDT/USDC to your wallet; NoxPos takes 0.3% from your fee account. No WordPress or Shopify required.

Scenario · Seat unlock

SaaS billing pages

Custom pricing page outside Stripe Checkout. Buyer pays USDC/USDT; your app provisions the workspace when the session settles.

  • Custom pricing UI — no full cart CMS.
  • Provision seats when the session flips paid.
  • API key stays server-side only.

Scenario · Usage meters

API credit top-ups

Metered APIs and AI endpoints. Embed a top-up button on the developer portal; credits land after on-chain confirm.

  • Embed top-up on the developer portal.
  • Credits mint after on-chain confirm.
  • Works with metered AI / API products.

Scenario · Tooling

CLI & docs paywalls

Paid npm packs, CLI licenses, or gated docs. Print a QR in the terminal or open a tiny local page — geek UX by design.

  • QR in terminal or tiny local page.
  • License npm packs and gated docs.
  • Built for geek UX, not storefront themes.

Scenario · One-off bills

Freelancer invoice pages

Static invoice URL per client: amount, memo, Pay Button. Client pays USDT; you reconcile with TxID instead of chasing bank wires.

  • One URL per client invoice.
  • Client pays USDT; you keep the TxID.
  • Skip slow international wires.

Scenario · On-chain culture

NFT mint / allowlist deposits

Collect a deposit or mint fee before allowlist mint. Session amount matches the drop; your mint backend listens for paid.

  • Deposit or mint fee before drop.
  • Mint backend listens for paid sessions.
  • Anti-mix amounts for noisy mempools.

Scenario · Support links

Creator tip jars

Link-in-bio or stream overlays with a sticky pay button. Tips settle to your wallet; platform fee stays off-chain.

  • Link-in-bio or stream overlay button.
  • Tips settle to your wallet.
  • Platform fee stays off-chain.

Scenario · Event SKUs

Indie game & hackathon merch

Weekend jam stores, itch.io add-ons, conference stickers. Spin a landing, embed the SDK, tear it down after the event.

  • Spin up a landing for the weekend.
  • Tear down after the event.
  • No long-lived cart CMS required.

Scenario · Ops tooling

Internal cost-center charging

Charge sister teams for GPU time or staging envs with a private billing page — crypto settlement without opening a public cart.

  • Private billing for sister teams.
  • GPU / staging cost recovery.
  • Crypto settle without a public store.

Scenario · No CMS cart

Static / Jamstack storefronts

Astro, Hugo, or plain HTML shops. Host on CDN; only the session API and SDK need a backend stub.

  • Astro, Hugo, or plain HTML.
  • CDN-hosted pages + thin session API.
  • SDK mounts where you already ship.

Scenario · Redirect fallback

Hosted-page hybrid handoff

Prefer in-page SDK for happy path; fall back to Hosted Pay Page redirect for email invoices or apps that cannot embed scripts.

  • In-page SDK for the happy path.
  • Hosted Pay redirect when embed fails.
  • One merchant, two surfaces.

Integration sketch

Server creates the session; browser shows the button/QR; your app unlocks after reconcile.

  1. 1

    Mint an API key

    Profile → API on noxpospay.com. Keep the key on the server only — never in client bundles.

  2. 2

    Create a checkout session

    Your backend calls NoxPos with amount, currency, and return/webhook hooks.

  3. 3

    Render Pay Button / QR

    Front end mounts the SDK against the session; guest pays from Phantom, OKX, Trust, TronLink, etc.

  4. 4

    Unlock on confirm

    Poll or webhook when status flips paid — then grant seats, credits, downloads, or ship goods.

Frequently asked questions

Server-side only. Create sessions from your backend; never ship noxpos_… keys in browser JS or mobile binaries.

Flat 0.3% per successful checkout from your fee account (prepaid or monthly). Same rate as Woo/Hosted — independent of Cashier VIP.

Usually no. Use the Woo gateway for cart checkout. Use the SDK for custom billing UIs, bots, CLIs, and sites without Woo.

TRON, Base, and Solana destinations you configure. Buyers typically pay from TronLink, MetaMask/OKX/Trust on EVM, Phantom/OKX on Solana — depending on the session networks you enable.
