CrawlCheck: AI-use declarations, top 10,000
What the top 10,000 sites declare about AI use, one signed line per site, for crawler operators to load before fetching. Each edition is a signed manifest plus gzip NDJSON parts.
Mirrored from crawlcheck.io/spec/rights-feed by the CrawlCheck Worker; the site is the canonical copy and is updated first. Measured by CrawlCheck's own observer. Free under CC BY 4.0: credit "CrawlCheck" with the URL of the file.
Each edition is a signed manifest (manifest.json, Ed25519 signature inside) and the parts it lists; verify a part by its sha256 in the manifest.
