Add Feed to FreshRSS

Given a feed URL, sample its content, infer the best category, and add it.

Environment

FRESHRSS_URL - Base URL of FreshRSS instance
FRESHRSS_API_USER - API username
FRESHRSS_API_PASSWORD - API password

Procedure

1. Authenticate

AUTH_TOKEN=$(curl -s -X POST "$FRESHRSS_URL/api/greader.php/accounts/ClientLogin" \
  -d "Email=$FRESHRSS_API_USER" \
  -d "Passwd=$FRESHRSS_API_PASSWORD" | grep -oP 'Auth=\K.*')

2. Fetch existing categories

CATEGORIES=$(curl -s "$FRESHRSS_URL/api/greader.php/reader/api/0/tag/list?output=json" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" | jq -r '.tags[].id' | grep 'label/' | sed 's|user/-/label/||')

3. Sample the feed

Use WebFetch on the feed URL to read its title, description, and recent post titles/summaries. This content is the basis for category inference.

4. Infer category

Compare the feed's content against the existing categories from step 2. Pick the best match. Consider:

Feed title and description
Topics of recent posts
Existing category names

If no existing category fits well, propose a short, lowercase category name consistent with the existing naming style.

Present the chosen category to the user with AskUserQuestion, showing existing categories as options plus the inferred pick marked "(Recommended)". Only skip confirmation if the match is obvious (e.g., feed title contains the category name verbatim).

5. Add the feed with category

RESULT=$(curl -s -X POST "$FRESHRSS_URL/api/greader.php/reader/api/0/subscription/quickadd" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" \
  -d "quickadd=FEED_URL")
FEED_ID=$(echo "$RESULT" | jq -r '.streamId')
curl -s -X POST "$FRESHRSS_URL/api/greader.php/reader/api/0/subscription/edit" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" \
  -d "ac=edit" \
  -d "s=$FEED_ID" \
  -d "a=user/-/label/CATEGORY_NAME"

6. Confirm

Print the feed title, URL, and assigned category. Verify by listing subscriptions:

curl -s "$FRESHRSS_URL/api/greader.php/reader/api/0/subscription/list?output=json" \
  -H "Authorization: GoogleLogin auth=$AUTH_TOKEN" | jq ".subscriptions[] | select(.id == \"$FEED_ID\") | {title, id, categories: [.categories[].label]}"

Notes

Token is session-based, get a fresh one each invocation
Feed IDs use format feed/https://example.com/rss
Fever API (/api/fever.php) is read-only, always use GReader API
