  • list_chains

    List supported chains (Base, Ethereum, Arbitrum, Optimism, Polygon, Solana) and the gas-unit constants used by the paid tools (free). Always returns the full, unfiltered list of all 6 chains (no input/filter params). gasUnits.{transfer|usdc_transfer|swap} are plain integers: the…

  • get_gas_price

    Current gas/fee tiers and USD costs for one chain. Slow/standard/fast gas tiers and USD cost of a transfer, USDC transfer and swap, for Base, Ethereum, Arbitrum, Optimism, Polygon or Solana. Updated every 15s. Solana is compute-unit pricing, not gwei-style gas; the other 5 are E…

  • compare_gas_costs

    Where is it cheapest to send this transaction right now?. Ranks all 6 supported chains (Base, Ethereum, Arbitrum, Optimism, Polygon, Solana) by USD cost for a transaction type (transfer, USDC transfer or swap) at a speed tier (slow/standard/fast). Returns the ranking, the cheape…

  • estimate_custom_tx_cost

    USD cost of a custom gas limit or compute-unit budget. Prices an arbitrary transaction, not just the 3 canned types get_gas_price/compare_gas_costs cover: pass your own gas limit (EVM chains) or compute-unit budget (Solana) and get its USD cost at a speed tier. Use this for a co…

  • read_url_as_markdown

    Check if a URL is reachable before paying to read it. HEAD request following up to five redirects: status code, final URL, content-type, content-length and last-modified — no page body fetched or charged for content. Use before read_url_as_markdown ($0.003) to confirm a URL reso…

  • get_native_token_price

    USD price of a chain's native token, no gas data. Just the native-token USD price (ETH, POL or SOL), sourced from MEXC/Gate.io/Coinbase with the same price feed get_gas_price uses. Use this when you only need the asset price, not fees — get_gas_price and compare_gas_costs alread…
