DexBuilder Platform API overview

Use the DexBuilder Platform REST API for Broker asset configuration, user queries, deposits, and withdrawals.

The DexBuilder Platform API lets Brokers query asset settings and user balances and support onchain deposits and withdrawals.

​

Base URL

Production Base URL:

https://api.dexbuilder.com

Endpoint paths begin with /api/v4/dexbuilder. For example, GET /api/v4/dexbuilder/assets lists supported assets.

Every endpoint requires a Broker API Key. See Broker API Key and signing. User-level endpoints also require X-User-Wallet-Address; see Access on behalf of a user.

​

Endpoint groups

Group	Capabilities
Asset configuration	Assets, networks, availability, fixed fees, and withdrawal limits
User	User information, bound wallets, Vault balance, and fund statistics
Deposit	Fee estimate, signing data, status, and history
Withdrawal	Signing data, submission, status, history, and Solana ATA creation

Asset-configuration endpoints read Broker settings and do not require a user wallet. User, deposit, and withdrawal endpoints require X-User-Wallet-Address. Some endpoints also require x-perp-device-type or Idempotency-Key; see each endpoint’s request parameters.

​

Responses and errors

Successful business responses contain code, message, data, and trace_id. code=0 indicates success. The data structure is defined in each endpoint’s OpenAPI response model.

Errors may include a machine-readable label. Some downstream business and risk-control errors use HTTP 200, so check code or label as well as the HTTP status. Common labels include INVALID_ARGUMENT, MISSING_REQUIRED_HEADER, USER_NOT_FOUND, INVALID_ADDRESS, INVALID_DEVICE_TYPE, PROJECT_ACCESS_DENIED, PRODUCT_DISABLED, BUSINESS_ERROR, and RISK_CONTROL_REJECTED. See the endpoint model and shared API conventions for interpretation.

An accepted withdrawal submission is not an onchain final state. Query the corresponding status endpoint to determine the final result of a deposit or withdrawal.
