The Neon API is a RESTful service that allows for programmatic management of all Neon resources.

The following table provides a high-level overview of each concept. + +| Concept | Description | Analogy/Purpose | Key Relationship | +| ---------------- | ---------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------- | +| Organization | The highest-level container, managing billing, users, and multiple projects. | A GitHub Organization or a company's cloud account. | Contains one or more Projects. | +| Project | The primary container that contains all related database resources for a single application or service. | A Git repository or a top-level folder for an application. | Lives within an Organization (or a personal account). Contains Branches. | +| Branch | A lightweight, copy-on-write clone of a database's state at a specific point in time. | A `git branch`. Used for isolated development, testing, staging, or previews without duplicating storage costs. | Belongs to a Project. Contains its own set of Databases and Roles, cloned from its parent. | +| Compute Endpoint | The actual running PostgreSQL instance that you connect to. It provides the CPU and RAM for processing queries. | The "server" or "engine" for your database. It can be started, suspended (scaled to zero), and resized. | Is attached to a single Branch. Your connection string points to a Compute Endpoint's hostname. | +| Database | A logical container for your data (tables, schemas, views) within a branch. It follows standard PostgreSQL conventions. | A single database within a PostgreSQL server instance. | Exists within a Branch. A branch can have multiple databases. | +| Role | A PostgreSQL role used for authentication (logging in) and authorization (permissions to access data). | A database user account with a username and password. | Belongs to a Branch. Roles from a parent branch are copied to child branches upon creation. | +| API Key | A secret token used to authenticate requests to the Neon API. Keys have different scopes (Personal, Organization, Project-scoped). | A password for programmatic access, allowing you to manage all other Neon resources. | Authenticates actions on Organizations, Projects, Branches, etc. | +| Operation | An asynchronous action performed by the Neon control plane, such as creating a branch or starting a compute. | A background job or task. Its status can be polled to know when an action is complete. | Associated with a Project and often a specific Branch or Endpoint. Essential for scripting API calls. | + +### Understanding API key types + +When performing actions via the API, you must select the correct type of API key based on the required scope and permissions. There are three types: + +1. Personal API Key + +- Scope: Accesses all projects that the user who created the key is a member of. +- Permissions: The key has the same permissions as its owner. If the user's access is revoked from an organization, the key loses access too. +- Best For: Individual use, scripting, and tasks tied to a specific user's permissions. +- Created By: Any user. + +2. Organization API Key + +- Scope: Accesses all projects and resources within an entire organization. +- Permissions: Has admin-level access across the organization, independent of any single user. It remains valid even if the creator leaves the organization. +- Best For: CI/CD pipelines, organization-wide automation, and service accounts that need broad access. +- Created By: Organization administrators only. + +3. Project-scoped API Key + +- Scope: Access is strictly limited to a single, specified project. +- Permissions: Cannot perform organization-level actions (like creating new projects) or delete the project it is scoped to. This is the most secure and limited key type. +- Best For: Project-specific integrations, third-party services, or automation that should be isolated to one project. +- Created By: Any organization member. diff --git a/.agents/skills/neon-postgres/references/neon-rest-api/keys.md b/.agents/skills/neon-postgres/references/neon-rest-api/keys.md new file mode 100644 index 00000000..56da43f7 --- /dev/null +++ b/.agents/skills/neon-postgres/references/neon-rest-api/keys.md @@ -0,0 +1,92 @@ +## Overview + +This document outlines the rules for managing Neon API keys programmatically.
