import requests url = "https://api.knowhereto.ai/v1/jobs" headers = { "Authorization": "Bearer YOUR_API_KEY", "Content-Type": "application/json" } payload = { "source_type": "url", "source_url": "https://arxiv.org/pdf/1706.03762.pdf", "parsing_params": { "model": "base", "ocr_enabled": True } } response = requests.post(url, headers=headers, json=payload) print(response.json())
We added a page for the @ontos-ai/knowhere-claw package: install it, ground OpenClaw, and inspect evidence before answering.
Also live on ClawHub as Knowhere.
Main shift
Preview, reopen, and inspect the evidence surface before the agent answers.
This is the behavior users feel first when the plugin is present.
Quick install
Step 1
openclaw plugins install @ontos-ai/knowhere-clawStep 2
openclaw config set plugins.entries.knowhere.config.apiKey "sk_..."Step 3
openclaw plugins enable knowhereWhy it matters
OpenClaw keeps the agent loop. Knowhere adds high-fidelity parsing, chunk structure, preview paths, and raw result files that agents can inspect when the answer depends on tables, images, or layout-heavy PDFs.
