solana_sendTransaction | Submit a signed transaction to the network. Returns transaction signature. params: transaction* |
solana_getSlot | Get the current slot number. params: none |
aex402_listPools | 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. params: minTvl |

aex402_quote | Get a swap quote from an AeX402 pool. Calculates expected output, price impact, and fees without executing. params: 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, t params: none |
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 cre params: name*, ticker*, creator, description, image, links, pad, build |
solana_buildTransfer | Build a SOL or SPL token transfer instruction. Returns instruction JSON (programId, keys, data) for client-side TX construction and signing. params: from*, to*, amount*, mint |
aex402_buildSwap | 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. params: pool*, inputMint*, amount*, slippageBps, userWallet* |
agent_delegate | 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. params: session, role, message*, model |
ai_chat | Send a chat completion request to the aeX402 AI Router. Free tier: 3 calls/day. Paid: deducts credits based on token usage. params: model, messages*, max_tokens, temperature, reasoning_effort |
solana_rpc | 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 (rpc.slonana.com), which additionally exposes RPC methods no other network has: getAlpenglowHealth (consensus migration status), getBridgeStatus, getAexchanRela params: method*, params, network |
mcp_call | 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 names. params: server*, tool, arguments |
evm_rpc | 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). params: method*, params, network |
mcp_linq | 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. params: calls*, reduce, pipeline, linq, concurrency, ignoreFailures |
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, 421 params: fromChain*, toChain*, fromToken*, toToken*, fromAmount*, fromAddress*, toAddress |
bridge_status | 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). params: txHash*, bridge, fromChain, toChain |
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 PA params: type*, coin, user, rankBy, limit, dir, interval, startTime, endTime |
api_get | 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), params: path* |
discover_programs | 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 b params: chain |
describe_program | 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. params: chain*, address* |
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/propriet params: chain*, address* |
search_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 (canonical tokens from Hyperliquid spotMeta, top tokens from Blockscout, spam-filtered). Use this ins params: query, chain, limit |
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. params: none |
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 hi params: none |
search | 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. params: query* |
fetch | 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. params: id* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
