Discord API - Pros & Cons
Pros

- ✓200M+ monthly active users means your bot has immediate access to a massive potential audience
- ✓Excellent developer documentation and enormous community with battle-tested libraries for every major language
- ✓Real-time WebSocket gateway provides instant event delivery, ideal for responsive AI agent experiences
- ✓Structured Interactions system (slash commands, buttons, modals) eliminates message parsing complexity
Cons
- ✗Privileged intent verification process at 75+ servers can delay scaling and requires Discord approval
