Overview

This skill provides integration with V2EX API 2.0 Beta, allowing you to access V2EX forum functionality including notifications, topics, nodes, and member information.

Authentication

V2EX API 2.0 requires a Personal Access Token for authentication.

  1. Visit https://www.v2ex.com/settings/tokens to create a token
  2. Use the token in the Authorization header: Authorization: Bearer <your-token>
  3. Store your token securely (e.g., in environment variables)

API Base URL

https://www.v2ex.com/api/v2/

Available Endpoints

Notifications

Get Latest Notifications

GET /notifications

Optional parameters:

  • p - Page number (default: 1)

Example:

curl -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/notifications?p=1"

Delete a Notification

DELETE /notifications/:notification_id

Example:

curl -X DELETE \
  -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/notifications/123456"

Member

Get Your Profile

GET /member

Example:

  "https://www.v2ex.com/api/v2/member"

Token

Get Current Token Info

GET /token

Example:

curl -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/token"

Nodes

Get Node Information

GET /nodes/:node_name

Example:

curl -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/nodes/programmer"

Get Topics in a Node

GET /nodes/:node_name/topics

Example:

curl -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/nodes/programmer/topics"

Topics

Get Hot Topics (Classic API)

GET https://www.v2ex.com/api/topics/hot.json

Returns the currently trending topics across all nodes. No authentication required.

Example:

curl -s "https://www.v2ex.com/api/topics/hot.json"

Get Latest Topics (Classic API)

GET https://www.v2ex.com/api/topics/latest.json

Returns the most recent topics across all nodes. No authentication required.

Example:

curl -s "https://www.v2ex.com/api/topics/latest.json"

Get Topic Details (API v2)

GET /topics/:topic_id

Example:

curl -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/topics/12345"

Get Topic Replies (API v2)

GET /topics/:topic_id/replies

Example:

curl -H "Authorization: Bearer <token>" \
  "https://www.v2ex.com/api/v2/topics/12345/replies"

Rate Limiting

Default rate limit: 600 requests per hour per IP

Rate limit headers in responses:

  • X-Rate-Limit-Limit - Total allowed requests
  • X-Rate-Limit-Reset - Unix timestamp when limit resets
  • X-Rate-Limit-Remaining - Remaining requests in current window

Note: CDN-cached requests only consume rate limit on the first request.

Common Workflows

Check New Notifications

  1. Call GET /notifications to fetch latest notifications
  2. Parse the response for unread items
  3. Optionally delete notifications after reading

Browse Hot Topics

  1. Call GET /api/topics/hot.json to get trending topics (no token required)
  2. Parse response to see popular discussions across all nodes
  3. Use topic URLs or IDs to view details on V2EX website

Browse Node Topics

  1. Call GET /nodes/:node_name/topics to get topics
  2. Use topic IDs to fetch detailed information with GET /topics/:topic_id
  3. Fetch replies with GET /topics/:topic_id/replies

Monitor Specific Topics

  1. Store topic IDs of interest
  2. Periodically poll GET /topics/:topic_id for updates
  3. Check GET /topics/:topic_id/replies for new comments

Response Format

All API responses are in JSON format. Common fields include:

  • success - Boolean indicating request success
  • message - Error message if request failed
  • Data fields specific to each endpoint

Error Handling

Common HTTP status codes:

  • 200 - Success
  • 401 - Unauthorized (invalid or missing token)
  • 403 - Forbidden (insufficient permissions)
  • 404 - Not found
  • 429 - Rate limit exceeded
  • 500 - Server error

Best Practices

  1. Store Personal Access Tokens securely (environment variables, not in code)
  2. Handle rate limits by checking headers and implementing backoff
  3. Cache responses when appropriate to reduce API calls
  4. Use pagination for endpoints that support it
  5. Handle errors gracefully with user-friendly messages
