Felo X Search Skill

When to Use

Trigger this skill when the user wants to:

• Look up X (Twitter) user profiles by username
• Search for X users by keyword
• Get tweets from a specific X user
• Search tweets by keyword or advanced query
• Get replies to specific tweets

Trigger keywords (examples):

• English: twitter, tweet, X user, X search, tweets from, replies to, trending on X
• 简体中文: 推特, 推文, X用户, X搜索, 推文回复
• 日本語: ツイッター, ツイート, Xユーザー, X検索

Explicit commands: /felo-x-search, "search X", "search twitter"

Do NOT use for:

• General web search (use felo-search)
• Webpage extraction (use felo-web-extract)
• Generating slides (use felo-slides)

Setup

1. Get API key

1. Visit felo.ai
2. Open Settings -> API Keys

Error Handling

Common Error Codes

• INVALIDAPIKEY — API Key is invalid or revoked
• XSEARCHFAILED — X search request failed (check parameters or downstream error)

Missing API Key

If FELOAPIKEY is not set, display setup instructions and stop.

API Reference (summary)

• Base URL: https://openapi.felo.ai. Override with FELOAPIBASE env if needed.
• Auth: Authorization: Bearer YOURAPIKEY
• Endpoints:

- POST /v2/x/user/info — Batch get user profiles - POST /v2/x/user/search — Search users - POST /v2/x/user/tweets — Get user tweets - POST /v2/x/tweet/search — Search tweets - POST /v2/x/tweet/replies — Get tweet replies

Important Notes

• Always check FELOAPIKEY before calling; if missing, return setup instructions.

• Use pagination cursors (next_cursor) for fetching more results.
• For tweet search, advanced query syntax is supported (same as X advanced search).
