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.
