使用说明 (SKILL.md)

Crypto Fear & Greed Index API

Access the global crypto market sentiment baseline using the free Alternative.me API.

API Endpoint

Base URL: https://api.alternative.me/fng/

The API requires no authentication or API keys.

Get Current Sentiment

Fetch the latest daily Fear & Greed metric (0-100 score + classification label):

curl -s "https://api.alternative.me/fng/?limit=1"

Returns a JSON structure containing:

  • value: The 0-100 numerical score.
  • value_classification: The textual label (e.g. "Extreme Fear", "Fear", "Greed", "Extreme Greed").
  • timestamp: Unix epoch of the data point.

Common Use Cases

Sentiment Baseline Anchoring

When conducting qualitative sentiment analysis on news headlines or on-chain flows, first fetch the Fear & Greed index to anchor your assumptions about retail psychology.

  1. If value \x3C 25 (Extreme Fear): The market is highly sensitive to bearish catalysts. Price may be artificially depressed.
  2. If value > 75 (Extreme Greed): The market is euphoric and ignoring risk. High danger of sudden liquidations or corrections.
安全使用建议
This skill is low-risk: it only queries a public API and does not ask for secrets or install software. Before installing, confirm you trust the skill owner (source metadata is unknown) and that your agent environment permits outbound network calls to that API. Also consider rate limits and caching so repeated automated calls don't hit the public endpoint excessively. If you require stricter controls, restrict the agent's network access or run the query manually.
功能分析
Type: OpenClaw Skill Name: fear-and-greed-index Version: 1.0.0 The skill bundle is designed to fetch the Crypto Fear & Greed Index from `https://api.alternative.me/fng/` using a standard `curl` command, as described in `SKILL.md`. There is no evidence of malicious intent, data exfiltration, unauthorized execution, persistence mechanisms, or prompt injection attempts against the agent. The instructions in `SKILL.md` are purely descriptive and guide the agent on how to interpret and use the fetched public data, aligning perfectly with the stated purpose.
能力评估
✓ Purpose & Capability
The name/description (fetching the Fear & Greed Index) matches the instructions, which simply call the public Alternative.me API. No unrelated capabilities or requirements are declared.
✓ Instruction Scope
SKILL.md instructs a single network fetch (curl to https://api.alternative.me/fng/?limit=1) and explains how to interpret the returned JSON. It does not direct reading local files, accessing environment variables, or transmitting user data to other endpoints.
✓ Install Mechanism
No install spec or code files are present (instruction-only). Nothing is downloaded or written to disk by the skill itself.
✓ Credentials
No environment variables, credentials, or config paths are requested. This is proportional to the stated purpose (public API access requires no auth).
✓ Persistence & Privilege
always is false and there are no indications the skill requests elevated or persistent privileges. Autonomous invocation of the skill is allowed by default, which is expected for skills of this type.
如何使用
  1. 确保已安装 OpenClaw（本地或 Docker 部署）

  3. 安装完成后，直接呼叫该 Skill 的名称或使用 /fear-and-greed-index 触发
