Robinhood Chain API for launchpad and DEX builders

How launchpad, DEX and v4 hook teams use the Crius API for launch lifecycles, launchpad stats, creator fees, hook records and pool data on Robinhood Chain.

Teams that run a launchpad, a DEX front end, an aggregator or a Uniswap v4 hook on Robinhood Chain need the same data their users ask about: where each token is in its lifecycle, how the launchpad compares with others, what fees creators earn, whether a hook has a clean record, and the live state of every pool. The Crius API already decodes every launchpad event, curve, Uniswap pool and hook on the chain, so a team can build token pages, creator dashboards and analytics without writing and running its own indexer.

Endpoints builders use

GET/launchpads every supported launchpad with live stats: tokens launched, graduations, graduation rate, median blocks to graduate, traders, volume by quote asset, fees.
GET/token/{address}/launch one token’s launch: creator, curve, progress, raised amount, fee settings, graduation block and the pool it graduated into.
GET/token/{address}/fees fees around a token over a window (LP, hook, creator, protocol, gas) and who received and claimed them.
GET/hooks every v4 hook with pool count, volume, risk level and flags; filter by launchpad, verified or risk_level.
GET/hook/{address} one hook’s permissions, code, observed outcomes in its pools, code family and events.
GET/pool/{pool} one pool’s tokens, reserves, in-range liquidity, fee, hook, price, TVL and LP lock.
Token lists with launchpad=<id> for your own tokens, and the launches:<launchpad>, graduations:<launchpad> and pools:new stream channels.

Suggested architecture

Token pages from the lifecycle. /token/{address}/launch (Free, 2 credits) gives the curve, progress and graduation; /token/{address} (1 credit) the market. Cache bonding tokens briefly and graduated ones longer: their curve and graduation no longer change.
Live progress from the stream. Subscribe to launches:<your id> and graduations:<your id>, and to trades:<token> for the tokens on screen, instead of polling every curve.
Creator dashboards from fees. /token/{address}/fees (Starter, 5 credits) per token, per window. Group tokens by creator with the developer profile.
Compare launchpads daily. /launchpads is 1 credit for all of them; /launchpads/pons (one launchpad by id) adds 30 days of daily history.
Hook teams: watch your reputation. /hook/{address} (2 credits) shows what Crius sees in your pools, including observed.honeypot_pools, liquidity_pulled_pools and measured taxes. That’s what wallets and bots read before trading through your hook.

Frequently asked questions

How do I get my launchpad attributed by Crius?

Email support@crius.sh with your factory, curve, hook and locker contract addresses and a link to your docs. Until a factory is attributed, its tokens show a creation.attribution other than known_launchpad, and /launch returns data: null with meta.attribution = "unattributed_factory".

Does Crius index custom Uniswap v4 hooks?

Yes, every v4 hook on Robinhood Chain. Each is inspected and re-inspected every 30 minutes: permissions decoded from its address, its code and owner, what happened in its pools (honeypots, liquidity pulled, taxes) and its code family's history.

Can I stream new pools and launches?

Yes. On the WebSocket stream, pools:new pushes every new Uniswap v2, v3 and v4 pool with its hook permissions, launches:<launchpad> every new launch and graduations:<launchpad> every graduation with the new pool.

How are launchpad fees measured?

fees_usd_24h.lp is LP fees at each pool's fee (for v4, the swap's own fee). tax is token and hook taxes measured from trades. Taxes a hook takes in the quote currency on sells are not measured yet, as meta.notes says.
