Lithtrix

Gives Claude four core capabilities through Lithtrix's unified API: web search, URL browsing, persistent memory storage, and blob file handling. You get one API key from lithtrix.ai that unlocks all four functions, which means you can build agents that research topics, read web pages, remember context across sessions, and store arbitrary files without juggling multiple services. The Spark tier includes a free trial to test it out. Reach for this when you want to add external data access and stateful memory to Claude without wiring up separate services for search, storage, and scraping.
