Abstraxn

Abstraxn Agent Kit's public MCP server gives any AI agent instant access to Web3 and market data with no signup or API key required. Query live blockchain data including block numbers, gas prices, transaction status, and ERC-20 token information and prices across major EVM chains and Solana. You can also access x402engine's pay-per-call APIs for crypto market data, wallet, token and ENS lookups, on-chain transaction simulation, and flight and hotel search. Paid calls are settled directly from the caller's own crypto wallet through the x402 protocol, while Abstraxn never holds or custodies funds. Ideal for AI agents that need real-time blockchain, Web3, and market data without onboarding friction.

能力清单

工具	说明
network.blocknumber	Read the current chain head — EVM block number or Solana slot — for a supported network. Free, read-only, no wallet needed. Use this to confirm a network is progressing before submitting a transaction, correlate off-chain events with on-chain height, or choose a safe starting point when scanning logs. Pass `chain` as one of: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia. Omit `chain` (or pass `all`) to query every resolvable chain in one call.
network.transaction_status	Check the status of a transaction. Supports both EVM (transaction hash) and Solana (signature). Free, read-only. Use this to confirm a transfer landed, debug a failed transaction, or report status to a user. Both `chain` and `transaction_hash` are required. Available chains: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.
network.gas_info	Get the current gas price and EIP-1559 fee hints for an EVM chain. Free, read-only, no wallet needed. Use this to estimate transaction cost or explain fees to a user before they send a transaction. `chain` is required. Supported chains: ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.
network.token_info	Read ERC-20 token metadata — name, symbol, decimals, total supply — for a token contract on an EVM chain. Free, read-only. Pass `token` as a contract address (0x…) or symbol `USDC` / `USDC.e` on chains where a lookup is configured. This server never holds a caller wallet, so no balance is ever returned — only public token metadata. Both `chain` and `token` are required. Supported chains: ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia.
network.token_price	Get a spot token price from a public market API (CoinGecko). Free — no payment or wallet needed. Defaults to ETH/USD.
market.crypto	Crypto market-data lookups (CoinGecko-sourced pricing and market data), paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`: - search ($0.001): fuzzy-search coins by name/symbol. Requires `q`. Call this first to resolve a coin id before using price_feed or historical_data, both of which need an id (e.g. "bitcoin"), not a ticker. - price_feed ($0.001): current price (and optionally 24h change / market cap) for one or more coins. Requires `ids` (comma-separated coin ids). Optional `currencies` (comma-separated fiat codes, default "usd"), `include_24h` (default true), `include_mcap` (default false). - market_data ($0.002): coins ranked by market cap (or another order) — use for "top N coins" / market overview questions. Optional `currency` (default "usd"), `category`, `order` (default "market_cap_desc"), `limit` (1-250, default 100), `page` (default 1). - historical_data ($0.003): historical price/market cap/volume series for one coin. Requires `id`. Optional `currency` (default "usd"), `days` (lookback window or "max", default 30), `interval` (e.g. "daily"). - trending ($0.001): currently trending coins by search interest. No extra parameters. - token_prices ($0.005): DEX-derived prices for up to 200 tokens in one call. Requires `tokens`, an array of `{chain, token_address}` objects. Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
web3.lookup	Multi-chain wallet, token, ENS, and transaction-simulation lookups, paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`: - wallet_balances ($0.005): token balances for a wallet across 20+ chains. Requires `chain` and `address`. - wallet_transactions ($0.005): transaction history with asset transfers for a wallet. Requires `address`. Optional `chain`, `limit`. - wallet_pnl ($0.01): realized and unrealized profit/loss per token for a wallet. Requires `chain` and `address`. - token_metadata ($0.002): name/symbol/decimals for a token contract. Requires `chain` and `address`. - ens_resolve ($0.001): resolve an ENS name to an Ethereum address. Requires `name`. - ens_reverse ($0.001): resolve an Ethereum address to its ENS name. Requires `address`. - tx_simulate ($0.01): simulate an EVM transaction before sending — gas estimate, execution trace, revert reason. Requires `network_id`, `from`, `to`. Optional `value`, `data`, `gas`. Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
travel.search	Flight and hotel search, paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`: - flight_search ($0.02): live flight fares via Google Flights. Requires `origin`, `destination`, `departureDate`. Optional `returnDate`, `adults`, `children`, `travelClass`, `stops`, `maxPrice`, `currency`. - hotel_search ($0.02): live hotel prices/ratings via Google Hotels. Requires `q` (city or hotel name), `checkInDate`, `checkOutDate`. Optional `adults`, `children`, `sortBy`, `minPrice`, `maxPrice`, `hotelClass`, `currency`. Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.
