Public

Public REST endpoints use ${PUBLIC_ENDPOINT} as the base URL:

• Mainnet: https://mainnet-gw.sodex.dev/api/v1

• Testnet: https://testnet-gw.sodex.dev/api/v1

User

Query Subaccounts

GET ${PUBLIC_ENDPOINT}/user/{userAddress}/subaccounts

Get the user's primary account ID and subaccounts.

curl -X GET "${PUBLIC_ENDPOINT}/user/0x0123456789070ce8f0d6bab722103d12674bc257/subaccounts" \
  -H 'Accept: application/json'

Path Params

Name	Type	Required	Restrictions	Description
userAddress	HexString	true	valid EVM address	User EVM address

Response

Name	Type	Required	Description
code	int32	true	Response status code. 0 means success.
data	UserSubaccounts	true	Response data when code is 0. See UserSubaccounts.
timestamp	uint64	true	Response timestamp in milliseconds.

Use data.primaryAccountID as the trading accountID for builder-fee approval and as the builder ID when that account is the builder.

Query API Keys

GET ${PUBLIC_ENDPOINT}/user/{userAddress}/api-keys

Get API keys for the user's primary account by default, or an owned subaccount selected by accountID.

curl -X GET "${PUBLIC_ENDPOINT}/user/0x0123456789070ce8f0d6bab722103d12674bc257/api-keys?accountID=12345" \
  -H 'Accept: application/json'

code	int32	true	Response status code. 0 means success.
data	AccountAPIKeys	true	Response data when code is 0. See AccountAPIKeys.
timestamp	uint64	true	Response timestamp in milliseconds.

Add API Key

POST ${PUBLIC_ENDPOINT}/user/{userAddress}/api-keys

Add an API key to both spot and perps. Use permissions to disable selected API key permissions, or builder to approve a builder fee in the same signed action.

• Auth: signed write with the universal domain; X-API-Chain is required

curl -X POST "${PUBLIC_ENDPOINT}/user/0x0123456789070ce8f0d6bab722103d12674bc257/api-keys" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -H 'X-API-Chain: <API-Chain>' \
  -H 'X-API-Sign: <API-Sign>' \
  -H 'X-API-Nonce: <API-Nonce>' \
  -d <AddAPIKeyRequest | AddPermissionedAPIKeyRequest>

Path Params

Name	Type	Required	Restrictions	Description
userAddress	HexString	true	valid EVM address	User EVM address

Headers

Name	Type	Required	Description
X-API-Chain	uint64	true	Any uint64. Use this exact value as EIP-712 domain.chainId when generating X-API-Sign.
X-API-Sign	HexString	true	EIP-712 universal signature from the user's wallet
X-API-Nonce	uint64	true	Unique nonce in milliseconds

Request Body

See AddAPIKeyRequest or AddPermissionedAPIKeyRequest in Schema.

Additional Information:

• accountID must be the primary account ID or one of the subaccount IDs belonging to userAddress.

• The request succeeds only when both spot and perps accept it.

• builder, if provided, uses BuilderParams.

• permissions, if provided, is a bit mask where a set bit disables the corresponding APIKeyPermissionEnum.

• A permissioned API key must disable TRADE, CANCEL, or both; enabling both TRADE and CANCEL is not supported.

• builder and permissions cannot be used together in the same request.

Response

Name	Type	Required	Description
code	int32	true	Response status code. 0 means success.
data	null	true	No endpoint-specific response payload.
timestamp	uint64	true	Response timestamp in milliseconds.

Revoke API Key

API key revocation does not support the universal domain. To revoke an API key from both markets, submit two engine-specific requests.

1. Call DELETE ${SPOT_ENDPOINT}/accounts/api-keys with a spot domain signature. See Remove API Key in the Spot REST API.

2. Call DELETE ${PERPS_ENDPOINT}/accounts/api-keys with a futures domain signature. See Remove API Key in the Perps REST API.

Use the same RevokeAPIKeyRequest body for both calls, but sign each request separately with the account's master wallet. Engine-specific EIP-712 signatures use signature type 0x01; a universal 0x02 signature cannot be used for revocation. See Trading actions for signing details and REST API endpoints for the endpoint base URLs.

# Revoke from spot.
curl -X DELETE ${SPOT_ENDPOINT}/accounts/api-keys \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -H 'X-API-Sign: <SPOT-API-Sign>' \
  -H 'X-API-Nonce: <SPOT-API-Nonce>' \
  -d <RevokeAPIKeyRequest>

# Revoke from perps.
curl -X DELETE ${PERPS_ENDPOINT}/accounts/api-keys \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json' \
  -H 'X-API-Sign: <PERPS-API-Sign>' \
  -H 'X-API-Nonce: <PERPS-API-Nonce>' \
  -d <RevokeAPIKeyRequest>

Both calls are required. A successful spot revoke does not revoke the key from perps, and a successful perps revoke does not revoke it from spot. Each call returns its own response and can succeed or fail independently.

Query Builders

GET ${PUBLIC_ENDPOINT}/user/{userAddress}/builders

Get approved builders for the user.

curl -X GET "${PUBLIC_ENDPOINT}/user/0x0123456789070ce8f0d6bab722103d12674bc257/builders" \
  -H 'Accept: application/json'

Path Params

Name	Type	Required	Restrictions	Description
userAddress	HexString	true	valid EVM address	User EVM address

Response

Name	Type	Required	Description
code	int32	true	Response status code. 0 means success.
data	Builders	true	Response data when code is 0. See Builders.
timestamp	uint64	true	Response timestamp in milliseconds.

  -H 'X-API-Chain: <API-Chain>' \
  -H 'X-API-Sign: <API-Sign>' \
  -H 'X-API-Nonce: <API-Nonce>' \
  -d <ApproveBuilderFeeRequest>

Name	Type	Required	Restrictions	Description
userAddress	HexString	true	valid EVM address	User EVM address

X-API-Nonce	uint64	true	Unique nonce in milliseconds

Request Body

See ApproveBuilderFeeRequest in Schema.

Additional Information:

• accountID must be the primary account ID of userAddress.

• builderID is the builder's trading account ID. That account must exist in both spot and perps and have at least 100 vUSDC in each engine.

• A user may have at most 10 builder approvals at a time.

• The request succeeds only when both spot and perps accept it.

• maxFeeRate must be between 0 and 2000, inclusive. Spot orders are capped at 2000 (2%); Perps orders are capped at 200 (0.2%).
