Best When
You need to monitor or interact with Reddit communities for research, moderation, or community management automation.
Avoid When
You need high-volume historical Reddit data (pricing has changed significantly since 2023), or need reliable SLA.
Use Cases
- • Monitoring subreddits for mentions of topics or brands
- • Building Reddit bots for moderation, assistance, or entertainment
- • Research and sentiment analysis on community discussions
- • Aggregating top posts from specific subreddits for digests
- • Automating posting of regular content to subreddits
Not For
- • Large-scale data collection without paid data access agreement
- • Accessing deleted content or private subreddits without mod permissions
- • Commercial use of Reddit data without explicit licensing
Interface
Authentication
OAuth 2.0 required. Script apps use password grant for bot use. Web apps use authorization code flow. App-only (non-user) auth available for read-only access. User-Agent header must identify your app uniquely.
Pricing
API became controversial in 2023 when Reddit raised prices significantly. Free tier still exists for non-commercial use. Commercial/large-scale data access requires paid agreement.
Agent Metadata
Known Gotchas
- ⚠ User-Agent header must be in format 'platform:app_id:version (by /u/username)' or requests are rejected
- ⚠ OAuth token expires after 1 hour - agents must implement token refresh for long-running sessions
- ⚠ Subreddit content policies vary widely - what's allowed in one sub is banned in another
- ⚠ Pagination uses 'after' cursor (fullname of last item) not page numbers - must parse from response
- ⚠ Rate limit applies per OAuth client, not per user - multi-user bots can hit limits faster than expected
