Read any public web page as clean Markdown: main-content extraction (navigation, footers, scripts and hidden elements removed), headings, lists, tables, code blocks, links (absolute, deduplicated), images, plus title, description, canonical URL, language, author and publish date, and a content hash + fetch time as evidence. JSON and plain-text URLs are returned as-is. No JavaScript rendering. $0.0

Search Bluesky and Hacker News for every query; for a single public tag, also search Mastodon's anonymous tag timeline. Mastodon is not applicable to phrase search. A failure from any source promised for that query returns an uncharged error, never a partial paid result. Successful results include author, text, time, engagement and link. Twitter/X and TikTok are deliberately out of scope because t

Reddit comment-thread scraper — the comment tree of any Reddit post for AI agents. Pass a post URL and get the post plus its nested comments (depth- and limit-controlled): for each comment the author, body, score, nesting depth, parent id, permalink, OP flag, and timestamp; a truncated flag plus totalComments show when a thread has more than returned. No login, no Reddit API key. Analyze discussio

Check whether a Base transaction settled x402 payments (USDC transferWithAuthorization, EIP-3009): for each, the payer, the payTo address, the amount in USDC, the authorization nonce, the facilitator that sent it, and the seller behind the payTo address from Bazaar listings (origins and 30-day payers).
