Visual builder and AI quick start on every plan · MCP-ready for your agents · runs on your own server when you need it to
AI-powered extraction services charge model prices on every single request. Here the AI writes the recipe once — validated against the live page before you ever see it — and the deterministic engine runs it forever, for free.
Paste a URL and say what you want — "title, price and image of each product". The AI derives the JSON paths or CSS selectors, tests them against the live page, and hands you a working endpoint. On every plan, free included.
When a site redesigns and the selectors stop matching, the AI re-derives the recipe against today's page, verifies it extracts real data, swaps it in and notifies you. The old recipe is kept — nothing changes silently.
Watch a whole feed or a single field — a price, a stock count. Real changes reach you
in-app, by email, and over a result.changed webhook.
Reorders and noise don't count as news.
Agents can run your endpoints, list them, and create new ones from a sentence. Cached, structured, stable data costs an agent a fraction of the tokens of re-scraping a page.
{
"url": "https://core.yourplaceholder.com/api/v1/mcp",
"headers": { "Authorization": "Bearer pak_YOUR_KEY" }
}
Every endpoint can answer in clean, boilerplate-free markdown — items as linked sections, HTML stripped — instead of JSON. One query parameter.
GET /api/v1/exec/{token}?format=markdown
Some sources only answer a known IP. Some data lives on a network the cloud can't reach. Deploy an agent where the data is: it runs your endpoints from there and reports every result back, so monitors, webhooks and alerts keep working exactly as before.
The node pulls the endpoints you assign to it, runs them on its own schedule with the same engine, and pushes each result back. If it goes quiet, the platform takes the endpoints back until it returns.
docker run -d --name yp-node \
-e YP_MODE=node \
-e YP_HUB_URL=https://core.yourplaceholder.com \
-e YP_AGENT_TOKEN=agt_YOUR_TOKEN \
ghcr.io/yourplaceholder/core
A lighter option: the platform keeps the schedule and the parsing, and only the HTTP request leaves from your machine. Optional headless rendering for JavaScript pages. Pick Run through on any endpoint and you're done.
Agents only make outbound calls, so they work behind NAT and firewalls with nothing exposed. Each one has its own revocable token, shows online or offline in your settings, and falls back to the platform when you allow it.
Pulling data is half the job. The Library is where you turn it into something of your own: notes, guides, research, whole books, organized the way a bookshelf is and linked the way your thinking is.
Write in a fast Markdown editor with split preview and autosave. Link pages with
[[wikilinks]], see backlinks, tag with
#tags, jump anywhere with Ctrl+K, and restore any
earlier version of a page.
Save any result from any endpoint straight into a page, quoted with its source link. Then let the AI draft, summarize, rewrite or outline right inside the editor, using the same provider setup as the endpoint builder.
Export a page, a book or the whole library as Markdown: folders per book, front matter, wikilinks intact, images in an assets folder. It opens in Obsidian as-is, and imports back the same way.
