How it Works

PostHooks lets you define Hooks — custom Reddit monitors that send events when matching posts appear.

Each Hook can specify:

Subreddits (e.g. r/startups, r/machinelearning)
Keywords or regex for precise matching
LLM-based classification to detect intent, sentiment, or topic

When a post matches, PostHooks delivers a verified, retryable webhook (via Svix) to your endpoint — fast, secure, and reliable.

curl -X POST https://api.posthooks.io/v1/hooks   -H "Authorization: Bearer $TOKEN"   -d '{
    "subreddits": ["r/startups"],
    "keywords": ["launch", "funding"],
  }'
