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. # List all tokenization provider accounts > Returns the brokerage accounts at the provider that you can use to back advances. **Note:** This endpoint is only available for RWA Redemption Advance products with a provider connection. ## OpenAPI ````yaml openapi/credit.yaml get /v1/credit/tokenization/providers/{provider}/accounts openapi: 3.0.2 info: version: ${version} title: Credit API description: > The Circle Credit API provides access to credit facilities including Line of Credit, Settlement Advance, and RWA Redemption Advance products. **Line of Credit** enables direct drawdowns with auto-approval and asynchronous disbursement. Supports both fiat and crypto repayment. **Settlement Advance** requires a reserve-then-request flow with manual approval. Requires wire proof upload for disbursement approval. Supports fiat repayment only. **RWA Redemption Advance** advances the proceeds of a tokenized stock redemption. Requires an onchain Arc burn transaction hash. Supports both fiat and crypto repayment. Draws use one of two flows, depending on the credit line: - **Receipt flow:** a reserve-then-request flow with automated AI verification of an uploaded receipt. - **Tokenization flow:** for lines connected to a brokerage provider. A single request names the token burn and the brokerage sell orders for the underlying shares, and is validated inline with no reserve step. Use the list tokenization providers endpoint to tell which flow a line uses. servers: - url: https://api-sandbox.circle.com - url: https://api.circle.com security: [] tags: - name: Credit description: Get credit line details. - name: Credit Transfers description: Create, reserve, and manage credit transfers (drawdowns). - name: Credit Fees description: View fees charged on credit transfers. - name: Credit Repayments description: View and initiate repayments on credit transfers. - name: Credit Tokenization description: >- Create and view RWA Redemption Advances backed by a token burn and brokerage sell orders. paths: /v1/credit/tokenization/providers/{provider}/accounts: get: tags: - Credit Tokenization summary: List all tokenization provider accounts description: > Returns the brokerage accounts at the provider that you can use to back advances. **Note:** This endpoint is only available for RWA Redemption Advance products with a provider connection. operationId: listTokenizationProviderAccounts parameters: - $ref: '#/components/parameters/TokenizationProviderPath' responses: '200': description: Successfully retrieved a list of provider accounts. headers: X-Request-Id: $ref: '#/components/headers/XRequestId' content: application/json: schema: title: ListTokenizationProviderAccountsResponse properties: data: type: array items: $ref: '#/components/schemas/TokenizationProviderAccount' examples: Accounts: value: data: - providerAccountId: a7c1e3f0-5d2b-4c8e-9f61-2b7d4e8a1c90 status: active displayName: Treasury Brokerage Account '400': $ref: '#/components/responses/BadRequest' '401': $ref: '#/components/responses/NotAuthorized' '404': $ref: '#/components/responses/NotFound' security: - bearerAuth: [] components: parameters: TokenizationProviderPath: name: provider description: The tokenization provider, in lower case. in: path required: true schema: type: string enum: - alpaca example: alpaca headers: XRequestId: description: >- Universally unique identifier (UUID v4) for the request.
