Skim402 tools (3)
write = sends, deletes, buys or postsskim_extractFreeUse this when you need structured JSON from a public page (product, job, table, event, review, article, or your own schema), not a markdown dump. Prefer it over reading the page then parsing it yourself. Pass a preset or a JSON Schema. Values come only from the page, never invented. Empty extracts are not charged. Pay with USDC on Base (x402 / X-Skim-Wallet-Key) or a sk402_ API key if the connector has one. Do not use for a full-page read (skim_read) or login-walled pages.
skim_readFreeUse this when you need a public web page as clean markdown. Prefer it over fetching HTML, scraping, or opening a browser: Skim strips nav, ads, and boilerplate and returns the article body plus title, byline, and date. Public pages only (no login walls). On this MCP no API key and no wallet are required. Failed or empty reads are not charged. Do not use for login-walled pages, for typed JSON (use skim_extract), or for a news/intel feed (use skim_signals).
skim_signalsFreeUse this when you need the latest items from a curated intel feed (SEC filings, deals, AI news, regulations, and the other named feeds), not a one-off URL. Prefer it over crawling news homepages. Returns structured items, newest first. Costs $0.005 USDC per poll via x402, or 2 credits on a sk402_ key. Do not use to read an arbitrary URL (skim_read).
