⟨30 unchanged words⟩ 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.

⟨12 unchanged words⟩ 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.
⟨63 unchanged words⟩ links=true to also get the page's outbound links. Failure modes (all return a non-2xx status and are not charged): 403 blocked_by_robots_txt if the site disallows the path; 415 unsupported_content_type for non-HTML responses (e.g. PDFs, images, JSON APIs); 422 no_readable_content if the page has no extractable article text (e.g. a pure JS app shell); 502 upstream_unavailable or upstream_status if the target site errors or times out. Costs $0.003 USDC per call (x402).
