# Build on Radius

*Accept payments, make payments, and set up your tools*

Start with the payment task you need. The setup guides cover wallets, testnet funds, and tooling.

## Payments

* [Accept payments](/build/accept-payments.md): charge for API routes in a Hono app or Cloudflare Worker with `radius-sdk`.
* [Make payments](/build/make-payments.md): pay x402 endpoints from an app or agent with `radius-sdk`, or from a terminal with `radius-cli`.
* [x402 payments](/build/x402.md): how a paid request works on Radius, for custom integrations.

## Tutorials

* [Sell a data lookup](/build/tutorials/sell-data.md): build a Worker that charges 0.001 SBC per request on testnet.
* [Buy a data lookup](/build/tutorials/buy-data.md): pay for it with a limit, confirm the settlement, and give it to an agent with a budget.

## Set up

* [**Claim and transact**](/build/claim-and-transact.md): Claim SBC and send your first transaction with the Dashboard or programmatically.
* [**Bridge stablecoins**](/build/bridge.md): Bridge USDC or SBC from Ethereum or Base to Radius.
* [**Build with LLMs**](/build/coding-assistants.md): Use Radius skills and radius-cli to accelerate agent-assisted development.
