In Claude Code: run /plugin marketplace add circlefin/skills then /plugin install circle-skills@circle. With Vercel Skills CLI: run npx skills add circlefin/skills. Available skills: use-usdc https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-usdc/SKILL.md (balances, transfers, approvals on EVM and Solana); EURC has no skill — see https://developers.circle.com/stablecoins/what-is-eurc.md; bridge-stablecoin https://github.com/circlefin/skills/blob/master/plugins/circle/skills/bridge-stablecoin/SKILL.md (crosschain transfers via CCTP, USDC, EURC, and third-party assets); use-arc https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-arc/SKILL.md (Arc chain config, contract deployment, USDC bridging — Arc docs: https://docs.arc.io/llms.txt); use-circle-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-circle-wallets/SKILL.md (choose wallet type); use-developer-controlled-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-developer-controlled-wallets/SKILL.md (custodial wallets for payouts and treasury); use-user-controlled-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-user-controlled-wallets/SKILL.md (embedded wallets with Web2 login); use-modular-wallets https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-modular-wallets/SKILL.md (smart contract wallets with passkeys and ERC-4337); use-gateway https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-gateway/SKILL.md (unified USDC balance, nanopayments); use-smart-contract-platform https://github.com/circlefin/skills/blob/master/plugins/circle/skills/use-smart-contract-platform/SKILL.md (deploy, interact, monitor contracts). Pair any skill with the Circle MCP server for live SDK signatures, contract addresses, and chain IDs: {"mcpServers":{"circle":{"url":"https://api.circle.com/v1/codegen/mcp"}}}. > Read the product overview first. Each product has an overview explaining when and why to use it. Read it before quickstarts. > Pick the right wallet type. Developer-controlled (you hold keys), user-controlled (end user holds keys via PIN/social login), or modular (smart contract wallets with passkeys). See https://developers.circle.com/wallets.md. > Use CCTP V2 for crosschain transfers. CCTP natively transfers USDC and EURC via burn-and-mint, and supports permissionless wrapping of third-party assets via lock-and-mint. V1 is legacy; always use V2 unless V1 is specified or the chain requires it (Noble, Sui, and Aptos still require V1). Migration guide: https://developers.circle.com/cctp/migration-from-v1-to-v2.md. > Use Bridge Kit for frontend bridging. Wraps CCTP with a simpler SDK for user-facing apps. Use CCTP directly for backend transfers. > Gas Station vs Paymaster. Gas Station sponsors gas for Circle Wallet transactions. Paymaster lets users pay gas in USDC. Different use cases — read both overviews. > Gateway Nanopayments for sub-cent payments. Gasless USDC micropayments down to $0.000001 via x402 and batched settlement. For pay-per-request APIs, AI agent payments, streaming. > Look up USDC addresses per chain. Never hardcode — use https://developers.circle.com/stablecoins/usdc-contract-addresses.md. > Prefer SDKs over raw API calls. Node.js and Python SDKs handle auth, retries, and errors. > API key required. Bearer token in Authorization header. Testnet and mainnet use separate keys and may use different base URLs depending on the product. > Set up webhooks when available. Most operations are async. Webhooks deliver transaction confirmations and state changes. > When calling list endpoints, paginate using pageSize and pageAfter until no nextPageAfter cursor is returned—stopping at the first page silently misses records. > Building an AI agent? Start with the Agent Stack—Circle CLI, agent wallets, and nanopayments built for autonomous use cases: https://developers.circle.com/agent-stack.md. # Get a deposit by ID > Returns a deposit by ID. ## OpenAPI ````yaml openapi/account.yaml get /v1/businessAccount/deposits/{id} openapi: 3.0.2 info: version: ${version} title: Core Functionality description: > All of Circle's APIs share a common set of core functionality that lets you manage your Circle Account in a programmatic way. With a Circle Account your business can deposit traditional money from 80+ countries and seamlessly convert them into "digital currency dollars": USDC. You can then use USDC for everyday payments and treasury flows. servers: - url: https://api-sandbox.circle.com - url: https://api.circle.com security: [] tags: - name: Balances description: Get information on settled and unsettled balances. - name: Payouts description: Create and get information on 1st party payouts. - name: Wires description: >- Create, get instructions, and get information on 1st party bank accounts for wire transfers. - name: CUBIX description: Create and get information on CUBIX accounts. - name: PIX description: Create and get information on PIX accounts. - name: Transfers description: Create and get information on 1st party transfers. - name: Addresses description: Generate and get information on blockchain addresses. - name: Deposits description: Get information on 1st party deposits. - name: Payments description: Create, cancel, refund, and get updates on card payments. - name: Settlement Bank Routing description: View and manage settlement bank routing preferences for fiat accounts. - name: Reporting description: >- Retrieve transaction and balance reports, including ISO 20022 (CAMT.053) statements and managed-payment reports. paths: /v1/businessAccount/deposits/{id}: get: tags: - Deposits summary: Get a deposit by ID description: Returns a deposit by ID. operationId: getBusinessDepositById parameters: - $ref: '#/components/parameters/IdPath' - name: type description: Filters results to get only deposits made by this specific type. in: query schema: type: string enum: - wire - name: walletId description: >- The wallet ID to which the deposits were made.
