Real-time Reddit data, one API call.
Fetch subreddit posts, post details and stats, comment threads, and keyword search from Reddit.
The Reddit API from Captapi gives developers reliable access to public Reddit data without building or maintaining scrapers — send one authenticated request and get clean, structured JSON back.
curl "https://api.captapi.com/v1/reddit/subreddit-posts?url=https%3A%2F%2Fwww.reddit.com%2Fr%2Ftechnology%2Fcomments%2F1a2b3c4%2Fexample_discussion_thread%2F" \
-H "Authorization: Bearer capt_live_..."What is the Reddit API?
Fetch subreddit posts, post details and stats, comment threads, and keyword search from Reddit. Every endpoint is a single authenticated GET request that responds with predictable JSON, so the data drops straight into dashboards, AI pipelines, RAG systems, and no-code automations. AI agents can call the same endpoints as MCP tools via @captapi/mcp.

Frequently asked questions
What is the Reddit API?+
The Reddit API is a REST API from Captapi that returns public Reddit data as clean, structured JSON. It covers 7 endpoints — Subreddit Posts, Post Details, Post Comments, Post Transcript, Search, Subreddit Details, and more — behind one Bearer API key, with no OAuth flow and no infrastructure to build or maintain.
What data can I get from the Reddit API?+
Fetch subreddit posts, post details and stats, comment threads, and keyword search from Reddit. Each endpoint is a single GET request that responds with predictable JSON fields, so the data is ready for dashboards, AI pipelines, and automations.
Do I need a Reddit developer account or OAuth?+
No. You only need a Captapi key (capt_live_...), sent as an Authorization: Bearer header. The same key works across all 32 platforms Captapi supports. We handle proxies, rate limits, retries, and parsing for you.
How much does the Reddit API cost?+
Reddit endpoints cost between 1 and 2 credits per call, depending on the endpoint and how many results you request. New accounts start with 100 free credits (no credit card). Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d.
Can AI agents use the Reddit API?+
Yes. Every Reddit endpoint is exposed as a tool in the official MCP server (@captapi/mcp) for Claude, Cursor, and VS Code, and is also available through the @captapi/cli CLI, an n8n community node, a Make.com app, and an Apify Actor.
Is the Reddit API suitable for production use?+
Yes. It is a stable REST API with predictable JSON, automatic retries, and upstream fallbacks. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Only successful responses consume credits — failed or empty results are never charged.
