What it does

Stack Exchange runs Stack Overflow and 170-odd Q&A sites on other topics, with a public API.

  • Searching recent questions on the sites listed in each project's profile (for example webapps or softwarerecs)

Get set up

  1. Optional: register an app at stackapps.com to get a key
  2. Paste the key in Settings → Conversations → Stack Exchange key
Open stackapps.com

Where it goes

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

Staying free

Larvabot only asks about the few sites your profile lists, well within the keyless limit for most projects.

Larva tip

Answers on Stack Exchange must solve the question on their own and say you made the tool. Link-only answers get deleted.

Fallback order

For conversations, Larvabot tries these in order and skips any that aren't set up, are out of free quota or are busy.
