From 42e951ef8432e4a77c33b64648de04552882d744 Mon Sep 17 00:00:00 2001 From: Bretton Date: Sat, 27 Dec 2025 17:34:43 -0800 Subject: [PATCH 1/4] feat(aggregators): add API key authentication for aggregator bot access MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add API key-based authentication allowing aggregators to post to communities via bot-like behavior. This complements OAuth for programmatic access. Key components: - API key generation, validation, and revocation endpoints - Encrypted OAuth token storage for session persistence - DualAuthMiddleware supporting API keys alongside OAuth - Database migrations for key storage with encryption at rest 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../aggregator/apikey_handlers_test.go | 972

API key routes and add metrics endpoint MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Register API key management routes in main.go (was missing) - Add metrics handler for monitoring API key service health - Improve error handling and validation in handlers - Refactor apikey_service for better token refresh flow - Update aggregator repo with
