`aex402_rh_pool`Get the live state of the aeX402 AMM on Robinhood Chain (EVM 4663) — the diamond-contract port of the Solana AMM.

`bridge_quote`Bridge/swap ANY asset across ANY chain via LI.FI (the engine behind Jumper) — e.g. Arbitrum USDC → Robinhood Chain (4663) USDG, or bridge into ETH for gas. Returns the best route (estimated output, fees, bridge used, duration) PLUS an unsigned transactionRequest (to/data/value/gasLimit) that the CALLER signs and submits on the fromChain — no keys are held here. Chains by id or key (1 Ethereum, 42161 Arbitrum, 8453 Base, 10 Optimism, 137 Polygon, 999 HyperEVM, 4663 Robinhood Chain). Tokens by symbol or 0x address.

Returns a curated seed MERGED with programs/contracts AUTO-DISCOVERED from recent block activity (refreshed hourly) — each carries an `activity` count of recent invocations/calls; entries with type "discovered" were seen live on-chain but not yet named. Use this to learn what is actually active on-chain right now, then describe_program to introspect any specific address.

`fetch`Fetch the full document for one search result id (from the search tool). Accepts token:<chain>:<address>, program:<chain>:<address>, or pool:<address>.

`hl_info`Query the Hyperliquid Info API — the perps/spot order-book data layer (read-only, no auth). The 'type' field selects the query: meta (perps universe + leverage), l2Book (order book for a coin), allMids (mid prices), clearinghouseState (a user's positions/margin), spotMeta, meta+assetCtxs (mark/funding/OI), candleSnapshot, and more. For type:metaAndAssetCtxs specifically: the raw response is TWO PARALLEL top-level arrays (universe names, asset contexts) correlated only by array position — do not try to read/scan it directly for '200+ coins' style questions (funding-rate outliers, biggest open interest, highest volume). Pass rankBy instead: it joins the two arrays server-side, sorts, and returns only the top N — the correct way to answer 'what has the highest/most extreme funding/OI/volume right now'.

`launch_token`Launch a memecoin on the aeX402 launchpad on Robinhood Chain (EVM 4663) for a FIXED rising bonding curve (1B supply, starts 0.000008 USDG and climbs ~3.6x, graduates at 10,000 USDG raised, quoted in USDG; the pool then opens just above the last sale price). You supply only identity — name + ticker (+ optional description/image/links). DEFAULT (custodial): the aeX402 backend SIGNS + SUBMITS the createVPool tx for you, so a claude.ai user with NO WALLET can launch in one call; returns {ok,status,txHash,vpId}. Optionally pass `creator` (a 0x address) to record as the coin owner. Pass build:true instead to get an UNSIGNED tx {to,value,data} to submit yourself (non-custodial — that requires `creator` and makes you the on-chain creator). A custodial call SIMULATES first, so a failure burns no gas: status "gated" means createVPool reverts in simulation (cause not determined — likeliest are the ticker still being claimed by a bonding coin or this vpId being taken; see `detail`/`revertData`), and status "unreachable" means the chain could not be reached, which is retryable. The launchpad is NOT chain-gated: createVPool simulates clean from an arbitrary sender (measured 2026-09-25).

`reconstruct_abi`Reconstruct a PARTIAL function/event interface for an EVM contract on a supported EVM chain from its BYTECODE — no source or verification needed. Extracts PUSH4 function selectors + recent event topic0 hashes and resolves the ones public signature DBs (openchain/4byte) know to human signatures. Works on UNVERIFIED contracts because bytecode is ground truth, but it is NOT a full ABI: novel/proprietary selectors DBs have never seen stay unresolved (decompile for those). Use it to understand what an unknown contract does before trusting behavior-based guesses.
