Lyrenth
Lyrenth turns any public URL into an AIDocument: clean Markdown plus title, description, and structure, with navigation and boilerplate stripped. Each read carries a provenance header showing the token count and how much smaller it is than the raw page. **read_url** reads one page. **read_urls** batches up to 20 in a single call, with per-URL error isolation so one failure does not block the rest. **check_usage** reports your plan tier, credits used, credits remaining, and the reset date. Reads resolve through Lyrenth's shared cache, so a page many agents want is served without hammering the origin. Backed by Lyrenth's independently built web index, over 1.9 billion pages and growing about 50 million a day. A free API key takes about a minute at https://lyrenth.com/signup.
