Reddit

Homepage of the internet

Reddit's API provides access to subreddits, posts, comments, users, voting, messaging, and moderation tools. You can read public content, submit posts, comment, search across Reddit, and manage subreddit moderation — all via OAuth-authenticated REST endpoints. Reddit is one of the richest sources of community discussions and sentiment data. For OpenClaw agents, Reddit is valuable for monitoring discussions about your products, tracking industry trends, researching community sentiment, and staying informed on niche topics. Your agent can watch specific subreddits, alert on mentions, summarize trending discussions, or gather competitive intelligence from relevant communities.

Frequently Asked Questions

Do I need OAuth to read public Reddit data?

You can read public data by appending .json to any Reddit URL without OAuth, but at a lower rate limit (10 req/min). OAuth tokens give 100 req/min and access to all endpoints.

Did Reddit's API pricing change recently?

Yes. In 2023, Reddit introduced paid API access for high-volume commercial use. Personal/non-commercial use with moderate volume remains free via OAuth. The free tier is sufficient for agent automation.

Can my agent post to Reddit?

Yes, with OAuth and appropriate scopes. However, Reddit aggressively bans bot-like posting behavior. Read-only monitoring is the safest use case for automation.
