TL;DR: Create the project: # Creating Neon projects via the API ## The trap Agents try to automate project creation but get stuck on auth: the Neon API needs a personal API key created in the Console, and the base URL is `console.neon.tech/api/v2`

## Fix
1. Create the project:.
   Expected: this specific failure stops.
2. Save the returned project ID; every branch/endpoint/database call needs it.
   Expected: this specific failure stops.
3. The new project comes with a default branch; create databases and roles through the API or Console as needed. ## Checklist - Region is set at project creation and cannot be changed later; pick the region closest to your app up front. - One API key per automation, so you can revoke individually. - Deleting a project is destructive; gate it behind human approval in any automation.
   Expected: this specific failure stops.

## Details
`console.neon.tech/api/v2` . There is no username/password flow for automation. ## The rule 1. In the Neon Console, generate an API key (keep it secret; it is a full-access credential for your account). 2. ```
POST YOUR_HOST.neon.tech/api/v2/projects
your auth header API key]
Content-Type: application/json
{
  "project": {
    "name": "[project-name]",
    "region_id": "[region, e.g. aws-us-east-2]"
  }
}
``` 3. 4.
