Get optimal swap route and price estimation across DEX protocols

post

Find the best possible swap route and price estimation by aggregating liquidity across multiple DEX protocols. Supports direct swaps and multi-hop routing.

Body

application/json

amountstringRequired

Amount of input token.

• If amount_in_decimal is true: amount is a decimal string (e.g., "1.5" ADA)
• If amount_in_decimal is false or omitted: amount is in the smallest unit (e.g., "1500000" lovelace) For ADA: 1 ADA = 1,000,000 lovelace. For other tokens: amount * (10 ^ decimals). Examples:
• "1.5" (with amount_in_decimal=true) means 1.5 ADA or tokens
• "1000000" (with amount_in_decimal=false) means 1 ADA or token with 6 decimals

token_instringRequired

Input token identifier:

• For ADA: use "lovelace"
• For other tokens: use "" format Example: "29d222ce763455e3d7a09a665ce554f00ac89d2e99a1a83d267170c64d494e" for MIN token

Example: lovelace

token_outstringRequired

Output token identifier:

• For ADA: use "lovelace"
• For other tokens: use "" format Must be different from token_in

Example: 29d222ce763455e3d7a09a665ce554f00ac89d2e99a1a83d267170c64d494e

slippagenumberRequired

Maximum acceptable slippage percentage:

• Examples: 0.5 means 0.5% slippage tolerance
• Used to calculate min_amount_out

Example: 0.5

allow_multi_hopsbooleanOptional

Control whether multi-hop swaps are allowed:

• true: Allow routing through multiple pools to find best price
• false: Only allow direct swaps through a single pool

Multi-hop swaps can often provide better prices by routing through intermediate tokens, but may have higher total fees due to multiple swaps. Example: ADA -> MIN -> iUSD might be more efficient than direct ADA -> iUSD

partnerstringOptional

Partner identifier for tracking and analytics:

• Optional string to identify the partner integration
• Used for volume tracking and potential fee sharing programs

amount_in_decimalbooleanOptional

If true, the amount field is interpreted as a decimal string (e.g., "1.5" ADA), not the smallest unit (e.g., "1500000" lovelace). If false or omitted, amount is in smallest unit.

Build unsigned swap transaction

post

Constructs an unsigned Cardano transaction for performing the swap operation. This endpoint uses the results from /estimate to build a valid transaction that can be signed by the user's wallet and submitted to the network.

The transaction will:

1. Take tokens from the sender's wallet

2. Execute swaps through specified DEX protocols

3. Return output tokens to the sender

4. Handle all necessary ADA deposits and fee payments

Body

application/json

senderstringRequired

Cardano wallet address that will:

• Provide the input tokens
• Pay transaction fees
• Receive output tokens

min_amount_outstringRequired

Minimum acceptable output amount Must be greater than or equal to the min_amount_out from the /estimate response to ensure price protection Examples:

• "1.5" (with amount_in_decimal=true) means 1.5 ADA
• "1000000" (with amount_in_decimal=false) means 1 ADA

inputs_to_choosestring[]Optional

Optional list of preferred UTxO inputs to use when building the transaction.

amount_in_decimalbooleanOptional

If true, the amount in the estimate is interpreted as a decimal string (e.g., "1.5" ADA), not the smallest unit (e.g., "1500000" lovelace). If false or omitted, amount is in smallest unit.

Get list of pending swap orders for a wallet

get

Retrieves all pending swap orders for a given wallet address across different DEX protocols. This endpoint is useful for:

• Finding orders that need to be cancelled

• Tracking pending transactions

Orders remain pending until they are either:

• Filled (swap completed)

• Cancelled (using /cancel-tx)

• Expired (if the DEX protocol supports expiration)

Query parameters

owner_addressstringRequired

Cardano wallet address to query pending orders for Must be in bech32 format Example: "addr1..."

amount_in_decimalbooleanOptional

If true, all token amounts are returned as decimal strings (e.g., "1.5" ADA), not the smallest unit (e.g., "1500000" lovelace). If false or omitted, amounts are in smallest unit.
