Use Cases

What can you build?

Any product that needs provable ownership, on-chain transfers, or tokenized value — powered by a single API key.

Tokenize Real-World Assets

Issue any physical or digital asset as an NFT — tickets, memberships, real estate, collectibles. One POST request, no gas management.

Marketplace & Storefronts

List, buy, and delist assets programmatically. Build a branded storefront backed by BrainArk's on-chain order book and escrow.

Read Live Chain Data

Query asset ownership, staking status, BAK balances, and campaign data — from any backend or frontend without running a node.

Webhooks & Events

Subscribe to on-chain events — asset issued, sold, claimed, unstaked — and receive real-time HTTP callbacks to drive your business logic.

Integration

From zero to on-chain in 4 steps

Create an API key

Connect your wallet, pick a plan, and get your key instantly. The free tier is always available — no payment required.

Add the auth header

Include Authorization: Bearer <key> on every request to any endpoint. No SDK or library needed.

Call the API

Use any language — JS, Python, curl, Go. Standard REST with JSON. Consistent error shapes across all endpoints.

Ship your product

Issue assets, manage listings, read ownership. Your UX, your product — BrainArk handles contracts and gas.
