What this server can do

32 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

aex402_buildSwap(pool, amount, inputMint, userWallet, slippageBps)

Build an AeX402 AMM swap action. Fetches live pool state, computes output with slippage protection, returns all instruction parameters and account addresses for client signing. Required: pool, inputMint, amount, userWallet.

aex402_getPool(address)

Get detailed AeX402 pool info: token mints, balances, fee, amplification, LP supply, analytics (OHLCV candles), circuit breaker status. Required: address.

aex402_listPools(minTvl)

List all AeX402 AMM pools on Solana. Returns pool addresses with basic info (mints, balances, fee, amp). Pools are 1024-byte accounts owned by program 3AMM53MsJZy2Jvf7PeHHga3bsGjWV4TSaYz29WUtcdje.

aex402_quote(pool, amount, inputMint)

Get a swap quote from an AeX402 pool. Calculates expected output, price impact, and fees without executing. Required: pool, inputMint, amount.

aex402_rh_pool

Get the live state of the aeX402 AMM on Robinhood Chain (EVM 4663) — the diamond-contract port of the Solana AMM. The AMM is the set of GRADUATED launchpad coins whose pools are seeded in-diamond on the canonical launchpad (0xED2F); this enumerates them live by scanning VPoolGraduated events + reading each pool's reserves, so it tracks reality as coins graduate. Returns graduatedPools[] (poolId, token, reserves, TVL), graduatedPoolCount, and status ("live" | "no-graduated-pools" | "unknown"), plus the legacy standalone 0xA1F6 USDG/WETH pool (legacy-drained). Distinct from the chain's Uniswap-fork DEX. No inputs.

agent_delegate(role, model, message, session)

Delegate a task to an independent specialist AI agent session. The delegate runs with full tool access and returns its response. Useful for breaking complex tasks into subtasks. Max depth: 3. Required: message.

ai_chat(model, messages, max_tokens, temperature, reasoning_effort)

Send a chat completion request to an AI model (GPT-4o, Claude, Llama, Gemini). Uses OpenRouter. Free tier: 3 calls/day. Paid: deducts credits based on token usage. Required: messages.

api_get(path)

GET any public read endpoint of rpc.aex402.com: /health, /credits?wallet=, /pumpfun?limit=, /pumpfun/tuple?mint=, /security/<pool>, /market/list, /sniper/leaderboard, /sniper/bets?id=, /settlement/<sig>, /settlements/<wallet>, /ai/models, /ai/stats, /leaderboard, /openapi.json, /llms.txt, /rh/pools (Robinhood), /hl/pools (HyperEVM), /base/pools (Base Uniswap v3), /eth/pools (Ethereum Uniswap v3), /arb/pools (Arbitrum Uniswap v3) Required: path.

bridge_quote(toChain, toToken, fromChain, fromToken, toAddress, fromAmount, fromAddress)

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. Required: fromChain, toChain, fromToken, toToken, fromAmount, fromAddress.

bridge_status(bridge, txHash, toChain, fromChain)

Track a cross-chain bridge submitted via bridge_quote — returns DONE / PENDING / FAILED plus the receiving-chain tx once it completes. Pass the source-chain tx hash (and the bridge tool from the quote for a faster lookup). Required: txHash.

describe_program(chain, address)

Introspect ANY specific program/contract address on a chain. Solana/Slonana: returns executable, owner, data size, and whether it is a known program. EVM: RPC-verified facts (is-contract, code size, ERC-20 name/symbol/decimals, EIP-1967 proxy → implementation) PLUS Blockscout explorer enrichment when available. Required: chain, address.

discover_programs(chain)

Discover on-chain programs/contracts across every chain this RPC supports (Solana, Slonana SVM, Robinhood, HyperEVM, Ethereum, Base, Stable, Plasma, Tempo, Codex). 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.

discovery_health

Report the freshness and health of the cross-chain program/token discovery pipeline: when the hourly cron last ran, how many programs/tokens each chain scan produced, and which scans failed. Use this to check whether discover_programs / search_tokens data is current before relying on it.

evm_rpc(method, params, network)

Call ANY EVM JSON-RPC method on a supported chain — eth_getBalance, eth_call, eth_blockNumber, eth_sendRawTransaction, eth_getLogs, ... Chains: robinhood (4663) / robinhood-testnet (46630), hyperevm (999), ethereum (1), base (8453), stable (988), plasma (9745), tempo (4217), codex (81224), arc (5042, Circle mainnet). Required: method.

fetch(id)

Fetch the full document for one search result id (from the search tool). Accepts token:<chain>:<address>, program:<chain>:<address>, or pool:<address>. Returns the entity detail (on-chain state for pools, census entry for tokens, registry/introspection for programs) as a document. Required: id.

hl_info(coin, type, user)

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. Required: type.

launch_token(name, build, image, links, ticker, creator, description)

Launch a memecoin on the aeX402 launchpad on Robinhood Chain (EVM 4663) for a FIXED pump.fun-style bonding curve (1B supply, starts 0.0001 USDG, graduates at 10,000 USDG raised, quoted in USDG). 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). Live create is gated on the launchpad facet upgrade (pending); until enabled a custodial call returns status "gated" and burns no gas. Required: name, ticker.

mcp_linq(linq, calls, reduce, pipeline, concurrency)

Primary LINQ-style MCP workflow tool. Run one bounded MCP call: fan out up to 32 READ-ONLY tool calls across chains, then compose the combined result with fluent chains like results.selectMany(...).where(...).groupBy(...).orderByDesc(...).take(...), JSON pipeline steps, or reducers. Use mcp_linq when you want one aggregate answer instead of N tool calls. Required: calls.

payment_help

How to pay for API access (x402 micropayments) — the complete self-serve guide for agents: current prices, every accepted asset/chain (USDC/USDT/SOL/ANSEM on Solana, ETH/USDG on Robinhood Chain, USDC/HYPE on HyperEVM), the merchant addresses, step-by-step topup → session-token → API-key flow, and how to attach credentials to MCP calls. This tool is FREE and NEVER rate-limited — call it when you hit a 402 / rate limit to convert into a paid session ($0.01 minimum buys 100 calls, no signup).

reconstruct_abi(chain, address)

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. Required: chain, address.

search(query)

Search the aeX402 universe by keyword: tokens (Robinhood Chain + HyperEVM census), known programs/contracts (Solana, Robinhood, HyperEVM, Slonana), and live AeX402 AMM pools. Returns a result list; pass a result id to the fetch tool for full detail. Use the specialist tools (search_tokens, discover_programs, aex402_listPools) when you already know the entity type. Required: query.

search_tokens(chain, limit, query)

Search the live token/NFT census for Robinhood Chain (4663) and HyperEVM (999) by symbol or name. Returns matching tokens with address, standard (erc20/erc721/erc1155), decimals, holders, market cap, and — for HyperEVM canonical tokens — live spot price + 24h volume. The census is refreshed hourly (canonical tokens from Hyperliquid spotMeta, top tokens from Blockscout, spam-filtered). Use this instead of discover_programs when you want a specific asset (e.g. "USDC on hyperevm", "stablecoins on robinhood") rather than the whole list.

solana_buildTransfer(to, from, mint, amount)

Build a SOL or SPL token transfer instruction. Returns instruction JSON (programId, keys, data) for client-side TX construction and signing. Required: from, to, amount.

solana_getAccountInfo(address, encoding)

Get raw account info (owner, lamports, data) for any Solana address. Required: address.

solana_getBalance(address)

Get SOL balance for a wallet address (in lamports). Divide by 1e9 for SOL. Required: address.

solana_getLatestBlockhash

Get latest blockhash for transaction building. Returns blockhash + lastValidBlockHeight.

solana_getSignaturesForAddress(limit, address)

Get recent transaction signatures for an address. Returns up to 20 most recent. Required: address.

solana_getSlot

Get the current slot number.

solana_getTokenAccountsByOwner(owner)

Get all SPL token accounts owned by a wallet. Returns mint, balance, decimals for each token. Required: owner.

solana_getTransaction(signature)

Get full transaction details by signature, including instructions, logs, and status. Required: signature.

solana_rpc(method, params, network)

Call ANY Solana-compatible JSON-RPC method by name — full RPC surface beyond the typed solana_* tools (getProgramAccounts, getBlock, getEpochInfo, simulateTransaction, ...). Defaults to Solana mainnet; pass network:slonana to query Slonana. Required: method.

solana_sendTransaction(transaction)

Submit a signed transaction to the network. Returns transaction signature. Required: transaction.
