}Authorizations
Production API key beginning with o1_launch_.
Body
application/json
Production chain ID: 8453 for Base, 4663 for Robinhood Chain, 143 for Monad, 5042 for Arc, 56 for BSC, or 196 for X Layer.
Available options:
8453, 4663, 143, 5042, 56, 196 Example:
8453
Wallet that will execute the prepared swap.
Pattern:
^0x[0-9a-fA-F]{40}$Example:
"0x1111111111111111111111111111111111111111"
Tracked launch token to buy or sell, returned as token.address by GET /tokens.
Pattern:
^0x[0-9a-fA-F]{40}$Example:
"0x1111111111111111111111111111111111111111"
buy spends the selected settlement asset for launch tokens; sell spends launch tokens for that asset. Settlement defaults to the pool quote.
Available options:
buy, sell Exact input in base units: settlement-token units (paired quote when omitted) for buy, launch-token units for sell. Range: 1 through uint128 max.
Pattern:
^(0|[1-9][0-9]*)$Example:
"1000000000000000000"
Slippage tolerance in basis points. 1 bps = 0.01%; 50 means 0.5%, 100 means 1%, and 300 means 3%. The swap reverts below the calculated minimum output.
Required range:
0 <= x <= 4999Example:
50
Optional admitted buy payment/sell receipt asset; omission retains the pool quote. GET /config quote swap_settlement_tokens lists reviewed candidates. Native uses zero address; Arc SwapX supports ERC20 USDC, not native-USDC swaps. Routes, actual units, approvals and final amount-specific execution are verified before signing. Arbitrary assets or routes are rejected.
Pattern:
^0x[0-9a-fA-F]{40}$Example:
"0x1111111111111111111111111111111111111111"
Optional eligible referral wallet. It cannot be the trader, creator, platform treasury, or router. Unsupported for wstO burn pools.
Pattern:
^0x[0-9a-fA-F]{40}$Example:
"0x1111111111111111111111111111111111111111"
Optional hook comment limited to 32 UTF-8 bytes.
Maximum string length:
32
