OpenClaw 评估

The skill is internally consistent with a Jina AI integration: it only needs a JINA_API_KEY and calls Jina endpoints to read/search the web; nothing in the files indicates unrelated or hidden behavior.

# Jina AI — Reader, Search & DeepSearch

Web reading and search powered by Jina AI. Requires `JINA_API_KEY` environment variable.

> **Trust & Privacy:** By using this skill, URLs and queries are transmitted to Jina AI (jina.ai). Only install if you trust Jina with your data.

> **Model Invocation:** This skill may be invoked autonomously by the model without explicit user trigger (standard for integration skills). If you prefer manual-only invocation, disable model invocation in your OpenClaw skill settings.

**Get your API key:** https://jina.ai/ → Dashboard → API Keys

## External Endpoints

This skill makes HTTP requests to the following external endpoints only:

| Endpoint | URL Pattern | Purpose |
|----------|-------------|---------|
| **Reader API** | `https://r.jina.ai/{url}` | Sends URL content request to Jina for conversion to markdown |
| **Search API** | `https://s.jina.ai/{query}` | Sends search query to Jina for web search results |
| **DeepSearch API** | `https://deepsearch.jina.ai/v1/chat/completions` | Sends research question to Jina for multi-step research |

No other external network calls are made by this skill.

## Security & Privacy

- **Authentication:** Only your `JINA_API_KEY` is transmitted to Jina's servers (via `Authorization` header)
- **Data sent:** URLs and search queries you provide are sent to Jina's servers for processing
- **Local files:** No local files are read or transmitted by this skill
- **Local storage:** No data is stored locally beyond stdout output
- **Environment access:** Scripts only access the `JINA_API_KEY` environment variable; no other env vars are read
- **Cookies:** Cookies are not forwarded by default; the `X-Set-Cookie` header is available for authenticated content but is opt-in only

## Endpoints

| Endpoint | Base URL | Purpose |
|----------|----------|---------|
| **Reader** | `https://r.jina.ai/{url}` | Convert any URL → clean markdown |
| **Search** | `https://s.jina.ai/{query}` | Web search with LLM-friendly results |
| **DeepSearch** | `https://deepsearch.jina.ai/v1/chat/completions` | Multi-step research agent |

All endpoints accept `Authorization: Bearer $JINA_API_KEY`.

### Basic Usage

```bash
# Plain text output
curl -s "https://r.jina.ai/https://example.com" 
  -H "Authorization: Bearer $JINA_API_KEY" 
  -H "Accept: text/plain"

# JSON output (includes url, title, content, timestamp)
curl -s "https://r.jina.ai/https://example.com" 
  -H "Authorization: Bearer $JINA_API_KEY" 
  -H "Accept: application/json"
```

Or use the helper script: `scripts/jina-reader.sh <url> [--json]`

#### Browser & Network

| Header | Query Param | Description |
|--------|-------------|-------------|
| `X-Timeout` | `timeout` | Page load timeout (1-180s) |
| `X-Respond-Timing` | `respondTiming` | When page is "ready" (`html`, `network-idle`, etc.) |
| `X-No-Cache` | `noCache` | Bypass cached content |
| `X-Proxy` | `proxy` | Country code or `auto` for proxy |
| `X-Set-Cookie` | `setCookies` | Forward cookies for authenticated content |

### Common Patterns

```bash
# Extract main content, remove navigation elements

  -H "Authorization: Bearer $JINA_API_KEY" 
  -H "X-Retain-Images: none" 
  -H "X-Remove-Selector: nav, footer, .sidebar, .ads" 
  -H "Accept: text/plain"

# Extract specific section
