Reddit API Reference

Authentication (OAuth2 Script App)

Reddit API requires OAuth2 authentication for all endpoints.

Step 1: Get access token (app-only / client_credentials):

curl -s -X POST "https://www.reddit.com/api/v1/access_token" \
  -u "$REDDIT_CLIENT_ID:$REDDIT_CLIENT_SECRET" \
  -d "grant_type=client_credentials" \
  -A "LibreFang Reddit Hand/1.0"

Response: {"access_token": "...", "token_type": "bearer", "expires_in": 86400, "scope": "*"}

Note: client_credentials provides app-only access. Most read endpoints (listing posts, fetching comments, searching) work normally. Posting and commenting use the app's identity. For full user-level actions (e.g., voting, managing subscriptions), the more complex OAuth2 authorization code flow is required.

All subsequent requests must include:

Authorization: Bearer $ACCESS_TOKEN
User-Agent: LibreFang Reddit Hand/1.0

Core Endpoints

Get subreddit posts (hot):

curl -s -H "Authorization: Bearer $ACCESS_TOKEN" \
  -A "LibreFang Reddit Hand/1.0" \
  "https://oauth.reddit.com/r/SUBREDDIT/hot?limit=25"

Get subreddit posts (new):

curl -s -H "Authorization: Bearer $ACCESS_TOKEN" \
  -A "LibreFang Reddit Hand/1.0" \
  "https://oauth.reddit.com/r/SUBREDDIT/new?limit=25"

Get subreddit posts (rising):

curl -s -H "Authorization: Bearer $ACCESS_TOKEN" \
  -A "LibreFang Reddit Hand/1.0" \
  "https://oauth.reddit.com/r/SUBREDDIT/rising?limit=25"

Submit a new post (self/text):

curl -s -X POST -H "Authorization: Bearer $ACCESS_TOKEN" \
  -A "LibreFang Reddit Hand/1.0" \
  -d "sr=SUBREDDIT&kind=self&title=TITLE&text=BODY" \
  "https://oauth.reddit.com/api/submit"

Submit a link post:

curl -s -X POST -H "Authorization: Bearer $ACCESS_TOKEN" \
  -A "LibreFang Reddit Hand/1.0" \
  -d "sr=SUBREDDIT&kind=link&title=TITLE&url=URL" \
  "https://oauth.reddit.com/api/submit"

Post a comment:

curl -s -X POST -H "Authorization: Bearer $ACCESS_TOKEN" \
  -A "LibreFang Reddit Hand/1.0" \
  -d "thing_id=FULLNAME&text=COMMENT_TEXT" \
  "https://oauth.reddit.com/api/comment"

Note: thing_id is the fullname of the parent (e.g., t3_abc123 for a post, t1_def456 for a comment).
