Request Parameters

Both GET and POST requests support the following parameters:

Parameter	Description	Example
`from`	The base token address	`So11111111111111111111111111111111111111112` (SOL)
`to`	The quote token address	`4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R` (RAY)
`amount`	The amount of the base token to swap. Can be a specific value, “auto” to use full wallet amount, or a percentage (e.g., “50%”) to use that portion of the wallet balance	`1`, `"auto"`, or `"50%"`
`slippage`	Maximum acceptable slippage percentage	`10`
`payer`	Public key of the wallet sending the transaction	`PAYER_ADDRESS`

Optional Parameters

Parameter	Description	Example
`priorityFee`	Amount in SOL to increase transaction processing priority	`0.000005` or set it to auto and provide an priority level
`priorityFeeLevel`	Required if priorityFee is set to auto	min, low, medium, high, veryHigh, unsafeMax, for more info read this blog post
`txVersion`	Transaction version (`"v0"` or `"legacy"`)	`"v0"`
`fee`	Charge a custom fee to your users for each transaction (earn sol for each swap)	`WALLET_ADDRESS:PERCENTAGE` (Add multiple fees by seperating with a comma)
`feeType`	Fee application type (default: `"add"`)	`"add"` or `"deduct"`

Note: The feeType parameter is set to "add" by default. The "deduct" option is only used when the from address is SOL.

Loading the Transaction

const serializedTransactionBuffer = Buffer.from(res.txn, "base64");
let txn;
 
if (res.type === 'v0') {
  txn = VersionedTransaction.deserialize(serializedTransactionBuffer);
} else {
  txn = Transaction.from(serializedTransactionBuffer);
}
 
if (!txn) return false;

Sending the Transaction

Using React Wallet Adapter

if (res.type === 'v0' && txn) {
  await wallet.signTransaction(txn);
}
 
const txid = await wallet.sendTransaction(txn, connection, {
  skipPreflight: true,
  maxRetries: 4,
});

Using NodeJS

const keypair = Keypair.fromSecretKey(bs58.decode('YOUR_SECRET_KEY'));
 
let txid;
 
if (res.type === 'v0' ) {
  const txn = VersionedTransaction.deserialize(serializedTransactionBuffer);
  txn.sign([keypair]);
 
  txid = await connection.sendRawTransaction(txn.serialize(), {
    skipPreflight: true,
  });
} else {
  const txn = Transaction.from(serializedTransactionBuffer);
  txn.sign(keypair);
  const rawTransaction = txn.serialize();
  txid = await connection.sendRawTransaction(rawTransaction, {
    skipPreflight: true,
  });
}

Fees

We charge a 0.5% fee on each successful transaction. For high-volume usage on public bots or sites, contact us via Discord or email ([email protected]) to discuss reduced fees.
