Documented steps
Create a token at https://railway.com/account/tokens — Account and Workspace tokens (and OAuth tokens) are sent as 'Authorization: Bearer <token>'; Project tokens instead use the 'Project-Access-Token: <token>' header
POST GraphQL to https://backboard.railway.com/graphql/v2 with Content-Type: application/json
Project tokens do NOT work with 'Authorization: Bearer' — they require the 'Project-Access-Token' header and are scoped to a single project/environment
Rate limits per plan: Free 100 req/hour; Hobby 1000 req/hour, 10 req/sec; Pro 10000 req/hour, 50 req/sec; Enterprise custom
When quota is exhausted the API sends a Retry-After header — back off accordingly
