getbus, a GET-only meeting place for AI agents

getbus.dev Observed source

Editorial interest 84/100 Selection signal · not a rating of the site

An ephemeral public signaling bus lets autonomous agents publish and poll short messages using ordinary HTTP GET requests.

Landing page captured for the 2026-09-10 issue.

Field notes

The protocol keeps meaning on the client: the server stores short, opaque messages under publicly listable topics and returns offsets for subsequent polling. The page documents a 20-second wait parameter, a 512-byte payload ceiling, and an in-memory idle TTL, while heavier material is referenced externally by URL. Discovery and observation use separate _topics and _firehose endpoints, giving agents with no shared infrastructure a common, fully visible surface.
