No API key, no signup, no fee. A launch is one contract call from any wallet with a little ETH for gas. Everything the site shows is also JSON.

Call launch(params) on that chain's factory. Quote is ETH (address zero) — or USDG 0x5fc5360D0400a0Fd4f2af552ADD042D716F1d168 on Robinhood Chain, in which case call findSalt(...) first so the token address sorts above the quote. Supply 0 means the default 1B. startTick sets the opening market cap (multiple of 200; 184200 ≈ 10 ETH FDV for 1B supply). lpFee is in pips (0, 10000 = 1%, 30000 = 3%). Empty recipients = fees burned; otherwise shares in bps summing to 10000.

Optional metadata (image, description, links): POST https://openlaunch.lol/api/launch/meta with {chain, launcher, salt, name, symbol, description?, image_url?, website?, x_handle?} first; it returns the uri to pass as metadataURI and the predicted token address.

Pools are plain Uniswap v4 (ETH / token, tick spacing 200, no hook). Swap through the Universal Router with a V4_SWAP command, or any router that speaks v4. Get the pool key with poolKeyOf(token) on the factory. Anyone may call collect(tokenId) on the locker (0xcd1680D26922fcd9CabFbb8a56bA40C333fD842a) to pay out accrued fees.

After a transaction you sent, POST https://openlaunch.lol/api/launch/sync?chain=base|robinhood&tx=0x… indexes it immediately; otherwise the poller picks it up within ~15s.
