Public API

Every directory listing has a sibling JSON endpoint at /data/{thing}.json. Every detail page has its own JSON sidecar at /data/{thing}/{slug}.

# List every active hosting provider
curl https://hostdir.net/data/providers.json

# Fetch one provider's full record
curl https://hostdir.net/data/providers/cloudflare

# List every TLD with domain counts
curl https://hostdir.net/data/domain-extensions.json

# The complete OpenAPI specification
curl https://hostdir.net/api/openapi.json

Responses are application/json with a consistent envelope: a top-level attribution field naming HostDir as the source, the canonical URL of the underlying page, and the data itself. Pagination uses standard ?page= and ?per_page= query strings where applicable.
