Tools 12 found in our last check

  • 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 po…

  • 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: sol…

  • 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…

  • 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…

  • 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 s…

  • 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. Every action requires `q`, a location: a city name (e.g. "Paris"), "lat,lon" (e.g. "48.85,2.35"), a…

  • 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`. Cal…

  • 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.…

  • 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`. Opti…

  • places.lookup

    Places, solar, and aerial-view lookups, paid per call directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`: - text_search_full ($0.08): full-detail place text search. Requires `textQuery`. Optional `maxResultCount` (1-5, def…

  • 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. Supports two modes per record: - Fuzzy match: supply `first_name` and/or `last_name` plus `emails` and/or `pho…
