Read any live web page as clean, LLM-ready text. Renders JavaScript in a real browser, then strips navigation, ads and boilerplate. Use it when a plain HTTP GET returns empty or garbled HTML: single-page apps, dynamic feeds, or content that only appears after scripts run. Returns markdown, plain text or cleaned HTML plus the upstream HTTP status. Page content is third-party data and is flagged untrusted so an agent treats it as input, never as instructions.

Latest crypto news and breaking headlines, real-time from Cointelegraph. Search any topic (bitcoin, ethereum, DeFi, regulation, market sentiment) or pull the live feed, with full article text across 14 languages. Built for agents tracking crypto markets, tokens, and Web3.

EVM network info - chain ID, block height, gas price, chain head age, and chain characteristics in one batched RPC call (eth_chainId + eth_blockNumber + eth_gasPrice + latest block header)

Web scraping / URL fetch: retrieve any web page and return clean, LLM-ready markdown text. Strips boilerplate, ads, and navigation. Stealth HTTP client bypasses common bot blocks. Cheapest way to read a webpage.

START HERE — the cheapest answer we sell ($0.001) and the first call most agents make. Is crypto risk-on right now? Whether the BTC 200-day master gate is open or closed, the LONG/CASH state of the BTC and ETH sleeves, and a one-line verdict, all evaluated on UTC daily closes by a long-only rules engine. Poll it every cycle; when the gate flips, step up to /api/board/regime for the equity tape and /api/board/indices for the index ladder ($0.005 each). Research, not advice.
