• aex402_getPool ~92 tokens
  Get detailed AeX402 pool info: token mints, balances, fee, amplification, LP supply, analytics (OHLCV candles), circuit breaker status.
• aex402_listPools ~112 tokens
  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_rh_pool ~205 tokens
  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 + readi
• agent_delegate ~206 tokens
  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.
• ai_chat ~316 tokens
  Send a chat completion request to the aeX402 AI Router. Free tier: 3 calls/day. Paid: deducts credits based on token usage.
• api_get ~188 tokens
  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
• bridge_quote ~398 tokens
  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 CAL
• bridge_status ~202 tokens
  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).
• describe_program ~195 tokens
  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 whe
• discover_programs ~240 tokens
  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 `a
• discovery_health ~109 tokens
  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 ~244 tokens
  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
• fetch ~152 tokens
  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.
• hl_info ~642 tokens
  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/fundi
• launch_token ~668 tokens
  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 a
• mcp_call ~216 tokens
  Call a tool on another MCP server this RPC federates with, for tools that have no equivalent in solana_rpc/evm_rpc (no underlying JSON-RPC method — e.g. Slonana's aea_list_services/aea_resolve agent registry). Known servers: slonana. Call that server's tools/list first if you don't know its tool nam
• mcp_linq ~1661 tokens
  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 whe
• payment_help ~167 tokens
  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 ho
• reconstruct_abi ~266 tokens
  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. Work
• search ~176 tokens
  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_
• search_tokens ~270 tokens
  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 (
