# POST /v2/fungible/msgs_direct

`POST /v2/fungible/msgs_direct`

This supports cross-chain actions among EVM chains, Cosmos chains, and between them. Returns minimal number of messages required to execute a multi-chain swap or transfer. This is a convenience endpoint that combines /route and /msgs into a single call.

## Request body

- MsgsDirectRequest
  - `source_asset_denom` string — Denom of the source asset
  - `source_asset_chain_id` string — Chain-id of the source asset
  - `dest_asset_denom` string — Denom of the destination asset
  - `dest_asset_chain_id` string — Chain-id of the destination asset
  - `amount_in` string — Amount of source asset to be transferred or swapped. If this is a swap, only one of amount_in and amount_out should be provided.
  - `amount_out` string — Amount of destination asset out. If this is a swap, only one of amount_in and amount_out should be provided. If amount_out is provided for a swap, the route will be computed to give exactly amount_out.
  - `chain_ids_to_addresses` object — Map of chain-ids to receipient and/or sender address for each chain in the path. Since the path is not known to the caller beforehand, the caller should attempt to provide addresses for all chains in the path, and the API will return an error if the path cannot be constructed.
  - `swap_venues` SwapVenue[] — Swap venues to consider, if provided (optional)
    - `chain_id` string — Chain ID of the swap venue
    - `name` string — Name of the swap venue
    - `logo_uri` string, nullable — URI for the venue's logo
  - `slippage_tolerance_percent` string — Percent tolerance for slippage on swap, if a swap is performed
  - `chain_ids_to_affiliates` object — Map of chain-ids to arrays of affiliates. Since cumulative_affiliate_fee_bps must be provided to retrieve a route, and the swap chain is not known at this time, all chains must have the same cumulative_affiliate_fee_bps otherwise the API will return an error.
  - `post_route_handler` union
    - CosmWasmContractMsgWrapper
      - `wasm_msg` CosmWasmContractMsg
        - `contract_address` string — Address of the contract to execute the message on

    - AutopilotMsgWrapper
      - `autpilot_msg` AutopilotMsg
        - `action` 'LIQUID_STAKE' | 'CLAIM'
        - `receiver` string
  - `timeout_seconds` string — Number of seconds for the IBC transfer timeout, defaults to 5 minutes
  - `allow_unsafe` boolean — Toggles whether the api should return routes that fail price safety checks.
  - `experimental_features` string[] — Array of experimental features to enable
  - `allow_multi_tx` boolean — Whether to allow route responses requiring multiple transactions
  - `bridges` BridgeType[] — Array of bridges to use
  - `smart_relay` boolean — Indicates whether this transfer route should be relayed via Skip's Smart Relay service
  - `smart_swap_options` SmartSwapOptions
    - `split_routes` boolean — Indicates whether the swap can be split into multiple swap routes
    - `evm_swaps` boolean — Indicates whether to include routes that swap on EVM chains
  - `allow_swaps` boolean — Whether to allow swaps in the route
  - `enable_gas_warnings` boolean — Whether to enable gas warnings for intermediate and destination chains
  - `go_fast` boolean — Whether to enable Go Fast routes
  - `fee_payer_address` string — Alternative address to use for paying for fees, currently only for SVM source CCTP transfers, in b58 format.
