Without a key

Google search, Google News, YouTube search, YouTube video details, YouTube transcripts, Reddit search and Google Maps search also work with no API key, over HTTP and MCP. Without a key, transcripts work for YouTube videos only, and you get the first page only. No other endpoints are available without a key. Free use is capped per IP address. Going over the cap returns a 429. Sign up for an API key to get 1,000 free credits, higher limits and every endpoint.
