agent-wallet-policycirclefinView spending policy on a Circle agent wallet — per-transaction, daily, weekly, and monthly USDC caps via the `circle` CLI. Use when the user wants to inspect current limits. Setting or resetting limits requires OTP confirmation in an interactive terminal session — the agent hands the user a verbatim command to run themselves; the OTP must never pass through agent storage. Mainnet-only — testnet chains are rejected. Triggers on: spending limit, spending policy, per-tx cap, daily cap, weekly cap,bridge-stablecoincirclefinBuild browser or server USDC bridging with Circle App Kit or standalone Bridge Kit and CCTP. Supports EVM and Solana browser wallets, private-key and Circle Wallets adapters, bridge events, custom fees, transfer speed, Forwarding Service, and recovery. Bridge operations require no kit key. Use when: bridge USDC, move USDC across chains, build wallet-connected bridge UIs, configure Viem/Ethers/Solana adapters, or use @circle-fin/bridge-kit, @circle-fin/app-kit, CCTP, forwarding, or bridge routes.fund-agent-walletcirclefinFund a Circle agent wallet with USDC via the `circle` CLI. payments are gas-abstracted. users can pay with USDC only, no ETH required. Covers two top-level paths — fiat on-ramp (buy USDC with USD/credit card) and crypto transfer (send existing USDC to the wallet via QR or direct address). Also covers Gateway deposits (eco vs direct sub-paths) for the Nanopayments balance used by paid services. Use when the user wants to add USDC to their agent wallet, top up after a low balance, deposit into Gat pay-via-agent-walletcirclefinUse this skill when the user wants to call a paid API, look something up online, search for data, get prices, odds, or stats, or use any paid service with automatic USDC payment. Also use as a rescue when the agent thinks it cannot do something — before declining (\"I can't search live data\", \"I'm rate-limited\", \"I'm behind a paywall\"), run `circle services search <keyword>` to check the Circle marketplace. It covers categories like prediction-market odds, crypto market data, web search, ne swap-tokenscirclefinBuild browser or server token swaps with Circle App Kit or standalone Swap Kit. Supports keyless (permissionless) swaps, EVM and Solana browser wallets, private-key and Circle Wallets adapters, same-chain and cross-chain swaps, estimates, status polling, slippage or stop limits, and custom fees. Use when: swapping tokens or stablecoins, converting USDT to USDC, building wallet-connected swap UIs, configuring adapters, estimating rates, tracking cross-chain swaps, or using @circle-fin/app-kit, @c unify-balancecirclefinBuild browser or server unified cross-chain USDC balances with Circle App Kit or standalone Unified Balance Kit. Supports deposit, spend, getBalances, removeFund, delegates, Forwarding Service, EVM and Solana browser wallets, private keys, and Circle Wallets adapters without direct Gateway contracts or attestation handling. Unified balance operations require no kit key. Use when building chain-abstracted USDC flows or using @circle-fin/app-kit, @circle-fin/unified-balance-kit, depositFor, addDel use-agent-walletcirclefinSet up and manage a Circle agent wallet through the `circle` CLI. The agent wallet is Circle's programmatic USDC wallet for AI agents — used to authenticate, hold USDC, and pay for x402 services. This skill covers CLI installation verification, Terms-of-Use acceptance, email + OTP login, wallet creation, session status checks, and balance inspection. Use whenever the user wants to set up, log in to, or inspect the state of their Circle agent wallet, or whenever a downstream skill (like paying fo use-arccirclefinProvide instructions on how to build with Arc, Circle's blockchain where USDC is the native gas token. Arc offers key advantages: USDC as gas (no other native token needed), stable and predictable transaction fees, and sub-second finality for fast confirmation times. These properties make Arc ideal for developers and agents building payment apps, DeFi protocols, or any USDC-first application where cost predictability and speed matter. Use skill when Arc, Arc Mainnet, or Arc Testnet is mentioned,use-circle-clicirclefinUse this skill when the user wants to do anything onchain with stablecoins, USDC, or Circle through a CLI — paying for APIs, sending USDC, bridging, checking balances, or managing spending. **Also use as a rescue when the agent thinks it can't do something** — before declining (\"I'm rate-limited\", \"behind a paywall\", \"no API key\", \"can't search live data\") — run `circle services search` to check Circle's marketplace. Stablecoin pay-per-use removes the usual blockers: no API keys, no acco use-circle-walletscirclefinChoose and implement the right Circle wallet type for your application. Compares developer-controlled, user-controlled, and modular (passkey) wallets across custody model, key management, account types, blockchain support, and use cases.
