API Introduction

The AutoGPT Platform provides an External API that allows you to programmatically interact with agents, blocks, the store, and more.

API Documentation

Full API documentation with interactive examples is available at:

https://backend.agpt.co/external-api/docs

This Swagger UI documentation includes all available endpoints, request/response schemas, and allows you to try out API calls directly.

Authentication Methods

The External API supports two authentication methods:

1. API Keys

API keys are the simplest way to authenticate. Generate an API key from your AutoGPT Platform account settings and include it in your requests:

GET /external-api/v1/blocks
X-API-Key: your_api_key_here

API keys are ideal for:

• Server-to-server integrations
• Personal scripts and automation
• Backend services

2. OAuth 2.0 (Single Sign-On)

For applications that need to act on behalf of users, use OAuth 2.0. This allows users to authorize your application to access their AutoGPT resources.

OAuth is ideal for:

• Third-party applications
• "Sign in with AutoGPT" (SSO, Single Sign-On) functionality
• Applications that need user-specific permissions

See the SSO Integration Guide for complete OAuth implementation details.

Available Scopes

When using OAuth, request only the scopes your application needs:

Scope	Description
IDENTITY	Read user ID, e-mail, and timezone
EXECUTE_GRAPH	Run agents
READ_GRAPH	Read agent run results
EXECUTE_BLOCK	Run individual blocks
READ_BLOCK	Read block definitions
READ_STORE	Access the agent store
USE_TOOLS	Use platform tools
MANAGE_INTEGRATIONS	Create and update user integrations
READ_INTEGRATIONS	Read user integration status
DELETE_INTEGRATIONS	Remove user integrations

Quick Start

Using an API Key

# List available blocks
curl -H "X-API-Key: YOUR_API_KEY" \
  https://backend.agpt.co/external-api/v1/blocks

Using OAuth

1. Register an OAuth application (contact platform administrator)
2. Implement the OAuth flow as described in the SSO Guide
3. Use the obtained access token:

curl -H "Authorization: Bearer agpt_xt_..." \
  https://backend.agpt.co/external-api/v1/blocks
