CommaFeed REST API Skill

Interact with a self-hosted CommaFeed RSS reader instance via its REST API.

Environment Variables (REQUIRED)

Before making any API calls, ensure these environment variables are set:

Variable	Description	Example
`COMMAFEED_HOST`	CommaFeed instance URL (with protocol, no trailing slash)	`https://commafeed.example.com`
`COMMAFEED_USER`	CommaFeed username	`admin`
`COMMAFEED_PASS`	CommaFeed password	`secretpass`

export COMMAFEED_HOST="https://commafeed.example.com"
export COMMAFEED_USER="admin"
export COMMAFEED_PASS="your-password"

If these are not set, ask the user to provide them before proceeding.

Authentication

All requests use HTTP Basic Auth:

curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  "$COMMAFEED_HOST/rest/category/get" | jq .

Every request pattern below assumes:

Base URL: $COMMAFEED_HOST/rest
Auth: -u "$COMMAFEED_USER:$COMMAFEED_PASS"
Content-Type: application/json (for POST requests with JSON body)

Helper alias for examples:

CF="curl -s -u $COMMAFEED_USER:$COMMAFEED_PASS"

Common Patterns

List all feeds with unread counts

  "$COMMAFEED_HOST/rest/category/get" | \
  jq '[.. | .feeds? // empty | .[] | {id, name, unread, feedUrl}]'

Get all unread entries across all feeds

curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  "$COMMAFEED_HOST/rest/category/entries?id=all&readType=unread&limit=100" | \
  jq '.entries[] | {title, url, feedName, date}'

Get starred entries

curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  "$COMMAFEED_HOST/rest/category/entries?id=starred&readType=all&limit=50" | \
  jq '.entries[] | {title, url, starred, date}'

Search entries by keyword

curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  "$COMMAFEED_HOST/rest/category/entries?id=all&readType=all&keywords=kubernetes&limit=50" | \
  jq '.entries[] | {title, url, feedName}'

Mark all entries as read

# Get current timestamp
TS=$(date +%s)000
curl -s -X POST \
  -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  -H "Content-Type: application/json" \
  -d "{\"id\": \"all\", \"read\": true, \"olderThan\": $TS}" \
  "$COMMAFEED_HOST/rest/category/mark"

Subscribe to a feed and put it in a category

# 1. Fetch feed info to verify URL
curl -s -X POST \
  -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://blog.example.com/feed"}' \
  "$COMMAFEED_HOST/rest/feed/fetch" | jq .

# 2. Subscribe
curl -s -X POST \
  -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "https://blog.example.com/feed",
    "title": "Example Blog",
    "categoryId": 10
  }' \
  "$COMMAFEED_HOST/rest/feed/subscribe" | jq .

Export OPML backup

curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  "$COMMAFEED_HOST/rest/feed/export" -o "commafeed-backup-$(date +%Y%m%d).opml"

Paginate through all entries

OFFSET=0
LIMIT=100
while true; do
  RESPONSE=$(curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
    "$COMMAFEED_HOST/rest/category/entries?id=all&readType=all&limit=$LIMIT&offset=$OFFSET")

  COUNT=$(echo "$RESPONSE" | jq '.entries | length')
  HAS_MORE=$(echo "$RESPONSE" | jq '.hasMore')

  echo "$RESPONSE" | jq '.entries[] | {title, date, feedName}'

  if [ "$HAS_MORE" = "false" ] || [ "$COUNT" -eq 0 ]; then
    break
  fi

  OFFSET=$((OFFSET + LIMIT))
done

Get entries by tag

curl -s -u "$COMMAFEED_USER:$COMMAFEED_PASS" \
  "$COMMAFEED_HOST/rest/category/entries?id=all&readType=all&tag=important&limit=50" | \
  jq '.entries[] | {title, url, tags}'

Node.js Example

const COMMAFEED_HOST = process.env.COMMAFEED_HOST;
const COMMAFEED_USER = process.env.COMMAFEED_USER;
const COMMAFEED_PASS = process.env.COMMAFEED_PASS;

const AUTH = 'Basic ' + Buffer.from(`${COMMAFEED_USER}:${COMMAFEED_PASS}`).toString('base64');

async function cfApi(method, path, body = null) {
  const url = `${COMMAFEED_HOST}/rest${path}`;
  const options = {
    method,
    headers: {
      'Authorization': AUTH,
      'Content-Type': 'application/json',
    },
  };
  if (body) options.body = JSON.stringify(body);
  const res = await fetch(url, options);
  if (!res.ok) throw new Error(`CommaFeed API ${res.status}: ${await res.text()}`);
  const text = await res.text();
  return text ? JSON.parse(text) : null;
}

// Get all subscriptions
const tree = await cfApi('GET', '/category/get');
console.log(tree);

// Get unread entries
const entries = await cfApi('GET', '/category/entries?id=all&readType=unread&limit=20');
for (const e of entries.entries) {
  console.log(`[${e.feedName}] ${e.title} — ${e.url}`);
}

// Subscribe to a feed
const subId = await cfApi('POST', '/feed/subscribe', {
  url: 'https://example.com/rss',
  title: 'Example Feed',
});
console.log('Subscribed, ID:', subId);

// Star an entry
await cfApi('POST', '/entry/star', {
  id: entries.entries[0].id,
  feedId: parseInt(entries.entries[0].feedId),
  starred: true,
});

Python Example

import os
import requests

COMMAFEED_HOST = os.environ["COMMAFEED_HOST"]
COMMAFEED_USER = os.environ["COMMAFEED_USER"]
COMMAFEED_PASS = os.environ["COMMAFEED_PASS"]

AUTH = (COMMAFEED_USER, COMMAFEED_PASS)
HEADERS = {"Content-Type": "application/json"}

def cf_api(method, path, json=None):
    url = f"{COMMAFEED_HOST}/rest{path}"
    resp = requests.request(method, url, auth=AUTH, headers=HEADERS, json=json)
    resp.raise_for_status()
    return resp.json() if resp.text else None

# Get category tree
tree = cf_api("GET", "/category/get")
for cat in tree["children"]:
    print(f"Category: {cat['name']}")
    for feed in cat["feeds"]:
        print(f"  {feed['name']} — unread: {feed['unread']}")

# Get unread entries
entries = cf_api("GET", "/category/entries?id=all&readType=unread&limit=20")
for e in entries["entries"]:
    print(f"[{e['feedName']}] {e['title']}")

# Subscribe to a feed
sub_id = cf_api("POST", "/feed/subscribe", {
    "url": "https://example.com/rss",
    "title": "Example Feed",
})
print(f"Subscribed, ID: {sub_id}")

# Export OPML
resp = requests.get(f"{COMMAFEED_HOST}/rest/feed/export", auth=AUTH)
with open("backup.opml", "w") as f:
    f.write(resp.text)

Error Handling

Code	Meaning
200	Success
400	Bad request (missing/invalid fields)
401	Not authorized (wrong credentials)
403	Forbidden (insufficient role — need ADMIN)
404	Resource not found (wrong feed/entry/category ID)
429	Too many requests (refreshAll rate limit)
500	Server error

Implementation Notes

Always read COMMAFEED_HOST, COMMAFEED_USER, COMMAFEED_PASS from environment variables — never hardcode
Authentication is HTTP Basic Auth, not API key headers
The /rest/server/get endpoint does not require authentication
Entry IDs follow the format feed/{feedId}:entry/{guid} — preserve them as strings
Timestamps are in milliseconds (Unix epoch) for newerThan / olderThan parameters
OPML import uses multipart/form-data, all other POST endpoints use application/json
The readType parameter is required for entry listing endpoints
Maximum limit is 1000 entries per request — use offset + hasMore for pagination
id=all means all feeds, id=starred means starred entries in category endpoints
Tags replace the full tag list on an entry — send the complete desired set
CEL filter expressions on subscriptions auto-mark non-matching entries as read
