Polymarket markets where smart money disagrees with the odds: scans the 30 busiest open markets every 15 minutes and returns those where skilled traders' money implies a different probability than the price, tempered against thin evidence, with a low, medium or high confidence rating. Data, not investment advice.

Search every indexed x402 resource across Coinbase Bazaar, Agent402 and Agentic Market in one call (7k+ tools): name, description, price, seller, network and real usage metrics (calls, unique buyers, settled volume), with per-source freshness data. The meta-tool for agents: find the right paid tool for any task first, then call it.

Discover a site's XML sitemaps (via robots.txt Sitemap: directives, an explicit sitemap URL, or the conventional /sitemap.xml) and parse them into a bounded list of URLs with their lastmod, changefreq and priority. Follows sitemap-index files to their child sitemaps. Fetches and URL counts are capped (with a `truncated` flag) to stay fast and memory-bounded. The reliable way for an agent to enumerate a site's pages.

Search and discover creators across multiple platforms using advanced filtering (location, gender, language, followers, engagement, audience demographics, brand deals, and more). Supports Instagram, YouTube, TikTok, Twitch, and Twitter. Returns paginated list of creator profiles with analytics. 0.01 upstream credits per creator returned.

Find out what people say about a topic or a specific link. Searches Hacker News (stories with their top-ranked comments), Bluesky posts and Lemmy threads (with top comments) in one call, by keywords or by URL (finds every thread that shared that link, useful for product launches, articles and competitors).

Dispatch a paid task to an RTP-registered robot. x402 payment held in escrow until completion.

Great-circle distance (km and miles) between two IP addresses, with each endpoint's city/country/lat/lng.

Calculates WGS84 great-circle distance and initial bearing. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.
