Jina AI - Web Reader, Search and Deep Search

Web reading and searching via Jina AI APIs. Fetch clean markdown from URLs (r.jina.ai), web search (s.jina.ai), or deep multi-step research (DeepSearch).

Security Scan

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.

Purpose & Capability

Name/description match the actual behavior: scripts call r.jina.ai, s.jina.ai, and deepsearch.jina.ai and require a JINA_API_KEY. Small documentation mismatch: the skill does not declare required binaries, but the shell scripts rely on curl and call python3 for URL encoding/JSON escaping; those runtime dependencies should be declared.

Instruction Scope

SKILL.md and the included scripts only instruct contacting the three Jina endpoints and sending the user-provided URL/query and the JINA_API_KEY. The scripts do not read arbitrary local files or access other environment variables; they parse and print responses to stdout.

Install Mechanism

No install spec (instruction-only) and included scripts are run directly. There are no downloads or archive extraction steps; nothing writes code to disk beyond the skill files themselves.

Credentials

Only JINA_API_KEY is required and is appropriate for a 3rd-party API integration. The SKILL.md explicitly states the API key is transmitted to Jina. No other credentials or unrelated env vars are requested.

Persistence & Privilege

always is false and the skill does not request elevated or persistent system privileges, nor does it modify other skills or system configuration. Model-autonomous invocation is enabled by default (platform default).

Assessment

This skill appears to do what it says: it sends the URLs/queries and your JINA_API_KEY to Jina's endpoints and returns results. Before installing: (1) only enable it if you trust Jina with the data you will send (URLs and queries and the API key are transmitted); (2) ensure your environment has curl and python3 available (the scripts use both but the skill metadata doesn't declare them); (3) store JINA_API_KEY safely (use a scoped/limited key if Jina supports it); (4) if you want to avoid autonomous invocations, disable model invocation for this skill in your OpenClaw settings; (5) review the included scripts yourself (they are short and readable) or install from the upstream GitHub repo to verify provenance.

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.

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.
