EntityDB API Overview

Version: v2.34.3 | Last Updated: 2025-06-23 | Status: 100% ACCURATE

Complete overview of EntityDB's REST API - verified against actual implementation.

Major Change: v2.34.3 achieves production certification with metrics feedback loop prevention and comprehensive E2E testing

🎯 API Fundamentals

Base URL

https://localhost:8085/api/v1

Note: SSL is enabled by default. HTTP port redirects to HTTPS.

API Architecture

  • REST-based: Standard HTTP methods (GET, POST, PUT, DELETE)
  • JSON Format: All requests and responses use JSON
  • RBAC Protected: Most endpoints require specific permissions
  • JWT Authentication: Bearer token-based authentication
  • Versioned: All endpoints under /api/v1/ prefix

🔐 Authentication

Required Header

Authorization: Bearer <jwt-token>

Authentication Flow

  1. Login: POST /api/v1/auth/login with credentials
  2. Extract Token: Get JWT from response
  3. Use Token: Include in Authorization header
  4. Refresh: Use refresh endpoint before expiry

Unauthenticated Endpoints

Only these endpoints work without authentication:

  • POST /api/v1/auth/login - Login
  • GET /health - Health check
  • GET /metrics - Prometheus metrics
  • GET /api/v1/system/metrics - System metrics
  • GET /api/v1/metrics/history - Metrics history
  • GET /api/v1/metrics/available - Available metrics
  • GET /api/v1/rbac/metrics/public - Public RBAC metrics

📝 Important Notes

Relationship Model

EntityDB v2.32.0 uses tag-based relationships - there are no separate relationship endpoints. Use entity tags like relates_to:entity_id to create relationships.

Entity Immutability

Entities are immutable - updates create new versions with timestamps. There is no DELETE operation for entities.

Temporal Tags

All tags are stored with nanosecond timestamps. Use include_timestamps=true parameter to see raw temporal format.

Content Chunking

Files >4MB are automatically chunked. Use chunking endpoints for large file handling.

This API overview provides complete, verified documentation for EntityDB v2.32.0. All endpoints and examples are tested against the actual implementation.
