As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • 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 cheapest chain, and any chains queried in parallel that didn't respond (in failed[]). Costs $0.005 USDC per call (x402).

  • get_gas_price

    Current gas and fee prices for one chain. Current gas and fee prices for Base, Ethereum, Arbitrum, Optimism, Polygon or Solana: slow/standard/fast tiers and the USD cost of a transfer, USDC transfer and swap. Updated every 15 seconds. Paid via x402: the first call returns 402 with payment requirements; retry with a PAYMENT-SIGNATURE header (or, over MCP, with payment in _meta["x402/payment"]) to get the 200 response — failed/unpaid calls are never charged. Costs $0.002 USDC per call (x402).

  • 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 gas units a typical transaction of that type costs on an EVM chain (evm) or in Solana compute units (svm) — multiply by the chain's current fee from get_gas_price to estimate USD cost yourself, or just call get_gas_price/compare_gas_costs which already does this.

  • read_url_as_markdown

    Convert any web page into clean, readable Markdown. Fetches a public web page and returns clean Markdown: title, byline, site name, excerpt, word count and article body. Respects robots.txt, blocks private hosts, follows up to five redirects, caps the page at 3 MB. links=true adds outbound links. Not charged on failure: 403 if robots.txt disallows the path, 415 for non-HTML, 422 if no article text extracts, 502 on upstream error. Costs $0.003 USDC per call (x402).
