Documented steps
Generate a Personal Access Token from your Supabase account at https://supabase.com/dashboard/account/tokens; keep it secret because it carries full user privileges.
Find your organization_id: GET https://api.supabase.com/v1/organizations with the Authorization header set to your personal access token, and copy the org id from the response.
Pick a region string (e.g. us-east-1, eu-west-1) and a plan value: free, pro, team, or enterprise.
POST https://api.supabase.com/v1/projects with the same Authorization header and a JSON body containing name, organization_id, plan, region, and db_pass; db_pass has a min length of 6.
Read the returned project 'ref' - the short project reference used in all subsequent /v1/projects/{ref} endpoints.
Wait for provisioning, then check GET https://api.supabase.com/v1/projects/{ref}/health until services report healthy.

Known gotchas
db_pass is required at creation and must be at least 6 characters; it is your Postgres superuser password, so store it safely.
plan and region are required and validated strictly; an invalid region or plan returns a 400/422.
All requests require HTTPS and the Authorization header; 401 means an invalid/expired token, 403 means insufficient permissions.
Standard rate limit is 120 requests/minute per user per project/organization; respect X-RateLimit-Remaining and back off on 429.
Creating a project triggers billing per the chosen plan; free projects are subject to Supabase's fair-use policy.
