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",

NewKnowhere x OpenClaw

GROUND 🦞OPENCLAW WITH KNOWHERE

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

Browse-first grounding

Preview, reopen, and inspect the evidence surface before the agent answers.

previewchunksraw files

This is the behavior users feel first when the plugin is present.

Quick install

Step 1

openclaw plugins install @ontos-ai/knowhere-claw

Step 2

openclaw config set plugins.entries.knowhere.config.apiKey "sk_..."

Step 3

openclaw plugins enable knowhere

Why 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.
