Raindrop.io API Skill

This skill enables interaction with the Raindrop.io bookmarks service through its REST API. Use curl and jq for direct REST calls.

Official API documentation: https://developer.raindrop.io/

Authentication

Token Resolution

Resolve the API token in this order:

  1. Check environment variable RAINDROP_TOKEN
  2. Check if the user has provided a token in the conversation context
  3. If neither is available, use AskUserQuestion to request the token from the user

To verify a token exists in the environment:

[ -n "$RAINDROP_TOKEN" ] && echo "Token available" || echo "Token not set"

Quick setup: For personal use or development, generate a test token at https://app.raindrop.io/settings/integrations — open your app and copy the "Test token". Test tokens do not expire.

For full OAuth2 flow details, see the Authentication section below.

Making Authenticated Requests

All requests require the Authorization header with Bearer token:

curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/ENDPOINT"

For POST/PUT requests with JSON body:

curl -s -X POST \
  -H "Authorization: Bearer $RAINDROP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"key": "value"}' \
  "https://api.raindrop.io/rest/v1/ENDPOINT"

Verifying Authentication

Test the token by retrieving the current user:

curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/user" | jq '.user.fullName'

Base URL and Conventions

  • Base URL: https://api.raindrop.io/rest/v1/
  • Data Format: JSON for all request/response bodies
  • Timestamps: ISO 8601 format
  • Rate Limit: 120 requests per minute per authenticated user
  • CORS: Supported for browser-based apps

Confirmation Requirement

Before executing any destructive action (DELETE, bulk update, move to trash), always ask the user for confirmation using AskUserQuestion. A single confirmation suffices for a logical group of related actions.

Destructive actions include:

  • Deleting raindrops, collections, or tags
  • Bulk updating or moving raindrops
  • Merging or removing tags
  • Removing collaborators from shared collections
  • Clearing trash

Read-only operations (GET requests) do not require confirmation.

Endpoints Reference

Authentication: OAuth2 Flow

Docs: https://developer.raindrop.io/v1/authentication/token

For apps accessing other users' data (not personal use), use the full OAuth2 flow:

Step 1: Authorise

Direct users to:

https://raindrop.io/oauth/authorize?client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_REDIRECT_URI&response_type=code

Step 2: Exchange Code for Token

curl -s -X POST "https://raindrop.io/oauth/access_token" \
  -H "Content-Type: application/json" \
  -d '{
    "code": "AUTH_CODE",
    "client_id": "YOUR_CLIENT_ID",
    "client_secret": "YOUR_CLIENT_SECRET",
    "redirect_uri": "YOUR_REDIRECT_URI",
    "grant_type": "authorization_code"
  }' | jq '.'

Response:

{
  "access_token": "...",
  "refresh_token": "...",
  "expires_in": 1209599,
  "token_type": "Bearer"
}

Step 3: Refresh Token

Access tokens expire after two weeks. Refresh with:

curl -s -X POST "https://raindrop.io/oauth/access_token" \
  -H "Content-Type: application/json" \
  -d '{
    "client_id": "YOUR_CLIENT_ID",
    "client_secret": "YOUR_CLIENT_SECRET",
    "refresh_token": "YOUR_REFRESH_TOKEN",
    "grant_type": "refresh_token"
  }' | jq '.'

Error Handling

Check HTTP status codes:

  • 200 - Success
  • 204 - Success, no content
  • 400 - Bad request
  • 401 - Authentication failed (check token)
  • 403 - Forbidden (insufficient permissions)
  • 404 - Resource not found
  • 429 - Rate limited (120 req/min exceeded)
  • 5xx - Server error

Example with Error Handling

response=$(curl -s -w "\n%{http_code}" \
  -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/raindrops/0")

http_code=$(echo "$response" | tail -1)
body=$(echo "$response" | sed '$d')

if [ "$http_code" -ge 200 ] && [ "$http_code" -lt 300 ]; then
  echo "$body" | jq '.'
else
  echo "Error: HTTP $http_code"
  echo "$body"
fi

Common Patterns

List All Bookmarks in a Collection

curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/raindrops/COLLECTION_ID?perpage=50" | jq '.items[] | {title, link}'

Create a Bookmark

curl -s -X POST \
  -H "Authorization: Bearer $RAINDROP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "link": "https://example.com",
    "title": "Example Site",
    "tags": ["reference", "example"],
    "collection": {"$id": COLLECTION_ID},
    "pleaseParse": {}
  }' \
  "https://api.raindrop.io/rest/v1/raindrop" | jq '.'

Search Bookmarks

# Search across all collections
curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/raindrops/0?search=YOUR_QUERY" | jq '.items[] | {title, link}'

# Search with tag filter
curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/raindrops/0?search=%23tagname" | jq '.items[] | {title, link}'

See references/search-operators.md for the complete search query syntax.

Move Bookmark to a Collection

curl -s -X PUT \
  -H "Authorization: Bearer $RAINDROP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"collection": {"$id": TARGET_COLLECTION_ID}}' \
  "https://api.raindrop.io/rest/v1/raindrop/RAINDROP_ID" | jq '.'

Get All Tags

curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/tags/0" | jq '.items[] | {tag: ._id, count}'

Create a Collection

curl -s -X POST \
  -H "Authorization: Bearer $RAINDROP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"title": "My Collection", "view": "list"}' \
  "https://api.raindrop.io/rest/v1/collection" | jq '.'

List All Collections (Root + Children)

# Root collections
curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/collections" | jq '.items[] | {id: ._id, title}'

# Child collections
curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/collections/childrens" | jq '.items[] | {id: ._id, title, parent: .parent."$id"}'

Paginate Through All Bookmarks

page=0
while true; do
  response=$(curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
    "https://api.raindrop.io/rest/v1/raindrops/0?perpage=50&page=$page")

  count=$(echo "$response" | jq '.items | length')
  echo "$response" | jq '.items[] | {title, link}'

  if [ "$count" -lt 50 ]; then
    break
  fi
  page=$((page + 1))
done

Export Bookmarks

# Export all bookmarks as CSV
curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/raindrops/0/export.csv" -o bookmarks.csv

# Export as HTML
curl -s -H "Authorization: Bearer $RAINDROP_TOKEN" \
  "https://api.raindrop.io/rest/v1/raindrops/0/export.html" -o bookmarks.html

Check if URL Already Saved

curl -s -X POST \
  -H "Authorization: Bearer $RAINDROP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://example.com"]}' \
  "https://api.raindrop.io/rest/v1/import/url/exists" | jq '.'

Pagination

Raindrop uses page-based pagination (not cursor-based):

  • page - Page number (0-indexed)
  • perpage - Items per page (max 50, default 25 for highlights)

When the number of items returned is less than perpage, you have reached the last page.

Nested Collection Structure

Collections are organised hierarchically. Reconstructing the full sidebar requires:

  1. GET /user - Returns groups array with collection ordering
  2. GET /collections - Root collections
  3. GET /collections/childrens - Nested collections

Root collection sort order is persisted in the user's groups[].collections array. Child collection sort order is stored in the collection's sort field.

Workflow Summary

  1. Resolve token - Environment, context, or ask user
  2. Verify authentication - Test with GET /user
  3. Read operations - Execute directly without confirmation
  4. Write operations - Ask for confirmation before executing
  5. Handle pagination - Loop with page number until items < perpage
  6. Parse responses - Use jq to extract and format data
