What it does

Linkup is a web search API designed for AI applications. It returns ranked results with page titles, URLs and text snippets.

  • Finding list posts, resource pages and directories when Tavily's monthly credits are spent
  • Finding Reddit threads through web search

Get set up

  1. Create an account at app.linkup.so
  2. Copy your API key into Settings → Search → Linkup API key
Open linkup.so

Where it goes

In the dashboard, open Settings and find the Search section. Secret values are encrypted before they're saved and only their last four characters are ever shown again.

Staying free

Larvabot caps Linkup at 3,500 searches a month and uses it right after Tavily, before any one-time credits.
