Documented steps
Export `RAILWAY_TOKEN` (Account Settings > Tokens or `railway token`).
POST to https://backboard.railway.com/graphql/v2 with `Authorization: Bearer $RAILWAY_TOKEN` and Content-Type application/json.
Run: `query project($id: String!){ project(id: $id){ volumes{ edges{ node{ id name createdAt } } } } }` with variables {"id":"<project-id>"}.
Read the volumes.edges[].node array for each volume's id, name, and createdAt.
Known gotchas
Lists are Relay-style: data is nested under edges[].node, not a flat array.
project(id:) requires the project id, not the project name.
Volumes per project are capped by subscription plan (Hobby/Pro differ); volumes created in different environments for the same service do not count toward the same-service limit.
