Tools as reported by the server

• 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 log
• 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, e
• 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-
• 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 retur
• network.token_price
  Get a spot token price from a public market API (CoinGecko). Free — no payment or wallet needed. Defaults to ETH/USD.
• network.prepare_transfer
  Build an **unsigned** native or token transfer transaction for a supported chain, from an explicit sender you provide. Free, read-only against the chain (nonce/gas/fees are read live) — this tool never signs, broadcasts, holds a key, or enforces any allowlist/spend limit. This server never binds a c
• weather.forecast
  Weather data from a global weather data provider — current conditions, short-range forecast, astronomy, historical, marine, and location search. Free, read-only, no wallet needed.

  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 resol
• 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.

• 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.

  Places, solar, and aerial-view lookups, paid per call directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed.

• social.profile_lookup
  Resolve person / social-profile identity for a batch of records, paid per call directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed.
