Use the `identifier… - [Get one wallet's balances](https://docs.etherfuse.com/api-reference/assets/get-one-wallets-balances.md): Reads one wallet, the one you name on the call. It never picks a wallet for you, so an organization with many registered wallets calls this once per wallet. - [Create bank account (presigned)](https://docs.etherfuse.com/api-reference/bank-accounts/create-bank-account-presigned.md): Registers a customer's Mexican bank account (CLABE) for on/off-ramp transactions.

Sign the `approvalMessage` from the order's `approval` with the owner's P-256 key and submit the signature as a **hex string** (Turnkey stamp envelopes are not accepted).

Use it to authenticate a WebSocket connection for live order and status updates. The org is taken from your verified API key, so the token is org-scoped and user-less. - [Connect to the live update stream](https://docs.etherfuse.com/api-reference/websocket/connect-to-the-live-update-stream.md): Opens a WebSocket that streams `order_updated` events for your organization. Authenticate with a token from `POST /ramp/ws-api-token` passed as the `token` query parameter; a browser cannot set an `Authorization` header on a WebSocket upgrade. The token is single-use and expires in 30 seconds. Each… - [Swap assets](https://docs.etherfuse.com/api-reference/swaps/swap-assets.md): Swaps two different crypto assets. Asynchronous. Returns `200 OK` with an empty body; track progress via webhooks. - [Regenerate swap tx](https://docs.etherfuse.com/api-reference/swaps/regenerate-swap-tx.md): Regenerates a transaction for a swap — useful when the transaction was not submitted before expiration. The updated transaction is returned via the `swap_updated` webhook. Returns `202 Accepted` if successful. - [Approve EVM token](https://docs.etherfuse.com/api-reference/sponsored/approve-evm-token.md): Generates an unsigned ERC20 `approve()` transaction that enables gasless offramps on EVM chains. When enabled for your organization, EVM offramp transactions no longer require the user to hold native gas tokens (e.g. ETH on Base) — Etherfuse covers the bridging cost and bundles it into the offramp f… - [Search customers](https://docs.etherfuse.com/api-reference/customers/search-customers.md): Retrieves a paginated list of customers.

The overall `status` matches the logic used for orders, so it stays consistent with whether the customer can transact, and `approved` is the only value that lets them. Submission details such as rejecti… - [Submit verification data](https://docs.etherfuse.com/api-reference/kyc/submit-verification-data.md): First call in the [KYC API](/guides/kyc-api) flow. Nothing else is accepted before it: `country` is what routes the customer to their country's requirements. - [Upload verification documents](https://docs.etherfuse.com/api-reference/kyc/upload-verification-documents.md): Upload the customer's documents as `multipart/form-data`.
