For Developers

Build AI agents on Radius

Sub-second stablecoin payments, x402 micropayment infrastructure, and developer tooling shaped for autonomous workflows. Drive the network from a CLI built for agent runtimes, or drop Radius expertise into your AI coding tools with Claude Code skills.

Install the CLI Install the Skills

radius-cli

A CLI wallet for the Radius Network

Modeled on Foundry's cast with a built-in account, x402 HTTP payments, and a non-interactive mode designed for AI agents. Install in one command.

npx radius-cli wallet new
npx radius-cli wallet send 0xRecipient 0.10 RUSD

Wallet operations

Create or import a keystore (Web3 Secret Storage v3, geth/foundry compatible). Sign messages, check balances, and send native or ERC-20 transfers — including stablecoins like RUSD and SBC.

radius-cli wallet balance
radius-cli wallet sign "hello"
radius-cli wallet send 0xTo 0.10 RUSD

x402 HTTP payments

Pay any 402-protected endpoint from the local wallet. Auto-pay below a threshold for autonomous workflows, or run with -y for any amount.

radius-cli wallet x402 get https://api.example.com/r \
  --x402-threshold 0.05
# or autonomous, any amount:
radius-cli wallet x402 get https://… -y

Reads, calls, and receipts

cast-style read calls with decoded results, plus tx, receipt, storage, code, and nonce lookups.

radius-cli call 0xToken \
  "balanceOf(address)(uint256)" 0xUser
radius-cli receipt 0xTxHash

Claude Code Skills

Radius expertise inside your AI coding tools

A Claude Code plugin marketplace from Radius. Skills bring the development playbook, x402 integration patterns, and faucet access to whatever you're building — invoked when the model needs them.

/plugin marketplace add https://github.com/radiustechsystems/skills.git
/plugin install radius@radius-dev-skill

radius-dev

End-to-end Radius Network development playbook. Covers viem, wagmi, Foundry, contract deployment, micropayment patterns, x402 integration, EIP-7966 sync transactions, stablecoin-native fees, and EVM compatibility.

x402

Integrate the x402 HTTP payment protocol on Radius. Add per-request micropayment gating to APIs, sign x402 payment headers, work with facilitators and Permit2 + EIP-2612 patterns.

dripping-faucet

Request testnet or mainnet tokens from a Radius faucet. Handles signed and unsigned drips with on-chain balance verification — ideal for first-run setup of new wallets.

Why Radius for agents

A network shaped for autonomous payments

Stablecoin-native fees

No volatile gas token. Pay fees in the same stablecoin you transact in — simpler accounting and predictable per-call costs for agent runtimes.

Sub-second finality

Designed for real-time metering and per-request settlement. Agents don't wait on confirmations to make their next decision.

x402 micropayments

Native support for HTTP 402 payment flows so APIs can charge per call and agents can pay programmatically.
