Douyin Creator Marketplace (Xingtu) Follower Growth Trend API

Call GET /api/douyin-xingtu/gw/api/data_sp/get_author_daily_fans/v1 for Douyin Creator Marketplace (Xingtu) Follower Growth Trend through JustOneAPI with end...

Security Scan

The skill is a thin JustOneAPI wrapper for a Douyin/Xingtu follower-trend endpoint and its requirements (node + JUST_ONE_API_TOKEN) match its stated purpose.

Purpose & Capability

The skill's name and description match its implementation: a single GET operation against https://api.justoneapi.com. Required binary (node) and the JUST_ONE_API_TOKEN credential are appropriate and expected for calling the described API.

Instruction Scope

SKILL.md instructs the agent to collect three query parameters and call the documented endpoint. The included bin/run.mjs only performs the described GET request and returns the backend JSON (it does not read other files, extra env vars, or exfiltrate data). One minor mismatch: SKILL.md asks the agent to produce a short endpoint-specific summary before returning raw JSON, while the bundled run.mjs only prints the JSON — but that is an agent-level presentation issue, not an action outside scope.

Install Mechanism

No install spec; this is instruction + a small runtime helper script. Requiring node is reasonable because run.mjs is a Node script. There are no remote downloads, extract steps, or non-standard installers.

Credentials

The skill requests a single credential JUST_ONE_API_TOKEN (declared as primaryEnv) which is necessary to authenticate to JustOneAPI. The runtime script only uses that token and no other secrets or config paths.

Persistence & Privilege

always is false and the skill does not request persistent system changes or modify other skills/config. The skill runs on demand and does not demand elevated or persistent privileges.

Assessment

This skill is a straightforward wrapper around JustOneAPI's Douyin/Xingtu follower-trend endpoint. Before installing, confirm you trust JustOneAPI and the publisher. Only provide a JUST_ONE_API_TOKEN that you control (do not paste tokens into chat). Note: the helper sends the token as a query parameter (per the OpenAPI spec in the bundle), which can be logged by intermediaries or servers — prefer a token with limited scope and lifetime, and revoke it if you stop using the skill. If you need the agent to produce summaries, ensure the agent handles that presentation (the bundled run.mjs prints raw JSON). If you want higher assurance, review the token usage and JustOneAPI's docs/privacy policy or run the script locally to inspect requests before granting the token to an automated agent.
