Persistent agents over HTTP.

Private beta

A mech is an agent with its own files and conversation history. Each task runs in a fresh sandbox that restores the mech’s last checkpoint.

How runs work

POST /v1/mechs/{id}/runs
  1. Run 01 · sandboxWrite note.txt
  2. CheckpointFiles + conversation
  3. Run 02 · sandboxRevise note.txt
Failed or cancelled runs keep the previous checkpoint. External tool actions are not undone.
