PebblePost

PebblePost Platform API

A live but publicly undocumented platform API surface behind the PebblePost PDM Manager application. Two hosts respond: api.pebblepost.com (an Express service that answers GET /health with {"status":"UP"} and returns a JSON error envelope of {message, errorType} on unknown paths) and api.pbbl.co (an AWS API Gateway that answers every path with HTTP 403 Missing Authentication Token). PebblePost publishes no API reference, OpenAPI definition, or self-serve credential flow for either host; access is arranged through a PebblePost account team.
