Tools & keys

Tools and keys overview

Every free service Larvabot can use, grouped by job, in the order it tries them, with a link to set up each key.

Updated

Every job in Larvabot has a list of services it can use, tried top to bottom. A service is skipped when it isn't set up, has used its free quota, or is having a bad day, so adding more keys makes Larvabot more reliable, never more expensive.
