http://localhost:<port>, where the port depends on which app’s Bridge you’re calling:
This reference documents the Post, Flock, and Loft routes. Migrate and Conform run Bridges too, but their routes aren’t documented here yet; drive them from the Migrate CLI and Conform CLI. The Pidgeon launcher has no Bridge of its own.
This reference documents the local Bridge HTTP contract for automation against a running desktop app. It has not been exhaustively cross-checked against every current Bridge route. If an example here 404s, prefer the CLI equivalent and treat the mismatch as a docs bug.
Authentication
The Bridge listens only on loopback, for the user signed into the app on that machine. Most routes need no token. Where a route is protected, include the app session’s credential: The free-versus-Pro boundary is enforced by the app and your Pidgeon account entitlements, not by an internet-facing permission model. A feature like AI Triage is a Post Pro feature even though its loopback route carries no separate auth.Response Format
Usage limits
Because the Bridge runs locally, there’s no network-abuse rate limit to enforce. Usage limits follow your account’s plan and entitlements, for example Flock’s population caps in the desktop app’s Population panel. Where a response includes rate-limit headers, they reflect the entitlement-based cap for that endpoint.Endpoint groups
Content type
All request and response bodies use JSON. SetContent-Type: application/json on all requests with a body.
