What it is

Operated by NICT, Japan's national information and communications research institute. The collected data supports AI research and, per the operator, is also provided to third parties including commercial companies.

What blocking it costs you

You are excluded from a national research corpus and from the commercial redistributions of it. This is a dataset-shaped block: one refusal, many downstream effects.

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.

curl -s 'https://www.pathwren.workers.dev/tools/verification-methods?crawler=icc-crawler&s=client-dossiers'

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.
