What it is

A hosted scrape-to-markdown service that LLM applications call to read pages. The requester is whoever is building on it, not Firecrawl itself, so volume and intent vary wildly.

What blocking it costs you

Applications built on Firecrawl cannot read your pages. This is increasingly how agents fetch the web, so it is a bigger block than its name suggests.

Ask this page a question, with one GET

A question about this page, answered by a call you can make right now — no key, no account, no JSON-RPC, nothing to assemble. The query string is already filled in with this page's own subject.

  How do I prove a request really is FirecrawlAgent? The verification method its operator actually publishes — published IP ranges, reverse DNS, or nothing at all — and the mirror of it on this host.

Every parameter above is a value the endpoint reads, not an address it visits: nothing is fetched on your behalf. Called without any parameter, each endpoint returns its own specification instead of an error. All of them.
