OpenClaw, meet
any URL on the internet.
Drop Meta-Extract into your OpenClaw agent as a single tool call. URLs go in, structured metadata comes out — OG, Twitter Cards, JSON-LD, favicon, canonical, RSS feeds, robots — billed per success. No SDK, no API key, no monthly seat for your agent to forget about.
Real OpenClaw agents that rely on this tool.
Each pattern below is a single OpenClaw agent with Meta-Extract registered as one tool. The math works because the agent only spends when it actually gets usable metadata back.
Triage URLs before reading them.
A research-side OpenClaw agent receives a topic, discovers candidate URLs, and pulls metadata to decide which ones are worth a full read. Saves tokens on long runs and keeps the agent's context window focused on actually relevant pages.
Render link previews on demand.
When a user pastes a URL into a chat surface, OpenClaw calls the tool, receives OG and Twitter Card data, and renders a rich preview card. No browser farm, no edge-case handling, no maintenance window when a publisher changes their HTML.
Audit thousands of pages without infra.
An OpenClaw agent walks a sitemap, calls Meta-Extract per URL, and surfaces missing og:image tags, broken canonicals, or robots directives that contradict the indexing strategy. Pay per audited page, not per seat.
Watch competitor blogs at scale.
A scheduled OpenClaw agent pulls metadata from a list of competitor blogs every morning, detects new posts via JSON-LD datePublished, and pings the team with title + summary + canonical. The agent never reads the full page unless the metadata signals it's worth it.
Stop wrapping subscription scrapers into your agent.
Register one tool, connect a wallet, and your OpenClaw agent gets structured metadata on every URL it cares about. Idle runs cost zero. Failed extractions cost zero. That's the entire deal.
- Single OpenClaw tool

OpenClaw-specific questions.
If something below doesn't cover your case, ping us — we work directly with OpenClaw builders, no SDR funnel.
How does this register as an OpenClaw tool?
+
It's a single POST endpoint with a typed body. You register it in OpenClaw the same way you'd register any HTTP tool — endpoint, schema, price-per-call. OpenClaw uses the price to enforce budget caps and to show the user what each agent run will cost before it runs.
Does OpenClaw need a long-lived API key?
+
No. Meta-Extract accepts x402-signed requests, so OpenClaw can pay per call from a wallet you connect. There's no shared secret to leak in agent logs or rotate every quarter.
What happens when an OpenClaw run hits its budget cap?
+
Meta-Extract returns whatever it has resolved so far and the OpenClaw budget enforcement stops the next call. The agent treats this as a normal tool boundary and can ask for more budget or hand off with a partial answer.
How does this save tokens for an OpenClaw agent?
+
Pulling metadata first lets the agent decide whether to fetch and read the full page. JSON-LD type, datePublished, og:description, and canonical URL are usually enough to triage. Skipping irrelevant pages compounds across long research runs.
What about JavaScript-rendered pages?
+
Meta-Extract reads the initial HTML response. SPAs that defer all metadata to client-side JavaScript will return partial coverage. For most publishers, the server-rendered HTML carries everything the agent needs.
How is this different from giving OpenClaw a subscription scraper?
+
Subscriptions don't fit OpenClaw's tool model. The tool can't report a true cost, so OpenClaw can't do real budget planning. Meta-Extract reports an honest per-call cost up front, which is what OpenClaw was designed to consume.
