Allocate (multi-op batch)

POST 
/v1/actions/allocate

Bundles multiple lending and token operations into a single composer transaction. Useful for portfolio rebalances, atomic deposit-then-borrow flows, or wrap/unwrap + deposit combos that should not be split across separate user signatures.

Request body: { chainId, operator, actions[] }. Each actions[] entry is { type, params } where type is one of Deposit | Withdraw | Borrow | Repay | Transfer | Wrap | Unwrap | Sweep. The params shape is action-specific (asset, amount, market, etc.) — see the AllocationAction schema.

Response: a single composer-call payload (operations / data / value) ready to send to the composer contract, plus permissionTxns for any required ERC20 approvals or borrow delegations.

Returns 422 with field-level details if validation fails (unknown action type, missing required params, incompatible chain/lender combo).

Plain-text reference — POST /v1/actions/allocate

Request body

Field	Type	Required	Description
chainId	string	yes	EVM chain id, as a decimal string. See the ChainId schema.
operator	string	yes
actions	object[]	yes
actions[].type	Deposit, Withdraw, Borrow, Repay, Transfer, Wrap, … (8 values)	yes
actions[].params	object	yes

Response 200

Field	Type	Description
success	True
data	object
data.operations	string
data.data	string	Informational payload. null when the endpoint only builds calldata.
data.value	string	Native-token value to send with the transaction, in wei.
data.permissionTxns	object[]	Approvals needed for this specific quote. Most integrators should use the deduplicated envelope-level actions.permissions instead.
data.permissionTxns[].to	string	Target contract address
data.permissionTxns[].data	string	Encoded calldata
data.permissionTxns[].value	string	ETH value
data.permissionTxns[].description	string	Human-readable description of the approval (e.g. "Approve borrow for AAVE_V3", "Approve ERC20")
data.permissionTxns[].spender	string	ERC-20 approve spender (x-chain permissions). Match it against the selected quote's approvalTarget — several bridges can share one spender, so do not match by description.
actions	object	Transaction calldata and approvals. Null for quote-only responses (no account provided).
actions.transactions	object[]	Pre-trade setup transactions (e.g. e-mode switch, collateral enable). Execute these before the main swap. Empty when no setup is needed.
actions.transactions[].to	string	Target contract address
actions.transactions[].data	string	Encoded calldata
actions.transactions[].value	string	ETH value to send with the transaction
actions.transactions[].description	string	Human-readable label. For alternatives, this is the aggregator name (e.g. "Paraswap"). For transactions, describes the setup action (e.g. "Switch e-mode to 1").
actions.alternatives	object[]	DEX aggregator swap transactions sorted by best output (descending). Each entry's description is the aggregator name. The client should pick one to execute. Present on loop action endpoints.
actions.alternatives[].to	string	Target contract address
actions.alternatives[].data	string	Encoded calldata
actions.alternatives[].value	string	ETH value to send with the transaction
actions.alternatives[].description	string	Human-readable label. For alternatives, this is the aggregator name (e.g. "Paraswap"). For transactions, describes the setup action (e.g. "Switch e-mode to 1").
actions.permissions	object[]	Approval/delegation transactions that must execute before both transactions and alternatives. Includes ERC20 allowances (targeting the composer contract) and lender borrow/withdrawal delegations (targeting the lending protocol contract directly). Filtered against on-chain state so only missing approvals are returned. Null when no approvals are needed.
actions.permissions[].to	string	Target contract address
actions.permissions[].data	string	Encoded calldata
actions.permissions[].value	string	ETH value
actions.permissions[].description	string	Human-readable description of the approval (e.g. "Approve borrow for AAVE_V3", "Approve ERC20")
actions.permissions[].spender	string	ERC-20 approve spender (x-chain permissions). Match it against the selected quote's approvalTarget — several bridges can share one spender, so do not match by description.

Responses

200

Allocation transaction

400

Validation error

422

Validation failed (e.g. unknown action type, missing required params)

429

Rate limited. Unauthenticated callers share a per-IP budget; send an x-api-key header to lift it. Retry with exponential backoff.

500

Unexpected server error. Safe to retry with backoff.

502

An upstream data source or protocol origin failed (error.code is ORIGIN_FAILED). error.details carries the per-origin status. This is also what a missing or malformed required parameter currently returns, rather than a 400.
