Sign in at https://bot.api.infinite.dev/mcp (production, acts as the user) or send `Authorization: Bearer ` to https://bot.api.infinite.dev/mcp/sse. Prefer its tools over raw HTTP; use REST only for steps no tool covers, and check `get_endpoint_schema` before guessing a request shape. > Net-new Infinite Connect (org_connect) is operator-assisted: do not grant end users shared org_connect Auth Kit membership or the shared platform org API key — those credentials are org-wide on /v1. BYO org keys onboard under that customer's org id. Operator sessions should show org_connect in get_organization_info. > The key decides the tools. Every organization key (`sk_sandbox_…` / `sk_live_…`) gets docs, onboarding, `get_account_balance`, and request logs for your own organization. BYO organizations add payees an agent will pay with `create_payee` (payable once ACTIVE). Platform Connect sessions instead get bound-customer payment lookups (`get_quote`, `get_transfer`, `list_transfers`, `list_account_balances`), payee drafts (`create_payee_draft` / `get_payee_draft`; screening only, never payable), and transfer drafts that wait for Infinite approval (`create_transfer_draft` / `get_transfer_draft`; never POST /v1/transfers). Where offered, platform `create_transfer` files a real transfer that Infinite holds in review before funding; it cannot be submitted from DRAFT. > An agent key (`sk_sandbox_agent_…` / `sk_live_agent_…`) moves money within that agent's limits: `create_transfer` → `submit_transfer` → `wait_for_transfer`. > On sandbox organization-key sessions, `sandbox_approve_customer` (makes the capabilities you pass READY, and related ones may turn READY too; `request_capabilities` is not needed), `sandbox_fund_account`, and `sandbox_complete_transfer` stand in for verification, funding, and settlement, so a whole flow runs from MCP. BYO keys can pass `customerId` on each call without binding; platform sessions must bind a customer first (`create_business_customer` auto-binds, or send `X-Infinite-On-Behalf-Of`). > When searching documentation without a key, use the docs MCP at https://docs.infinite.dev/mcp. > Start in sandbox (https://sandbox.api.infinite.dev). Do not use production unless the user explicitly asks. > Confirm amount, currency, and payee with the user before any payment is submitted. Pass the invoice number as `reference` on `create_transfer`; the summary says what the payee will see. > REST amounts are integer minor units (`"4000"` = 40.00 USD). MCP payment tools take exact decimal strings (`"40.00"`). Never mix them. > Agent denials return `403 { denial: { code, message, window, limit, used, remaining, attemptedAmount, currency }, hint }` with decimal amounts; per-transfer denials omit `used` and `remaining`. Report them to the user; do not work around them. # Close a balance account > Closes a balance account. The available balance must be zero and no payouts may be in flight — pay out any remaining funds first. After closing, the account no longer accepts deposits and (for STANDARD accounts that shared deposit coordinates) the customer can be issued bank pay-in fixed routes again. ## OpenAPI ````yaml delete /v1/balance-accounts/{id} openapi: 3.0.0 info: title: Infinite API description: API for Infinite version: '1.0' contact: {} servers: - url: https://sandbox.api.infinite.dev description: Sandbox - url: https://api.infinite.dev description: Production security: [] tags: - name: Accounts description: Virtual and external account management - name: Customers description: Customer identity management - name: Documents description: Document upload and management - name: Fixed Routes description: Fixed route management - name: External Bank Accounts description: External bank account management - name: External Wallets description: External wallet management - name: Infinite Wallets description: Infinite Wallet management - name: Organizations description: Organization management - name: Quotes description: Quote creation and management - name: Transfers description: Money movement and transaction tracking - name: Verification description: Identity verification workflows - name: Terms of Service description: Terms of Service acceptance - name: Health description: System health and monitoring - name: Sandbox description: Sandbox utilities paths: /v1/balance-accounts/{id}: delete: tags: - balance-accounts summary: Close a balance account description: >- Closes a balance account.
