Using the public network RPC
The dig RPC is the public read interface for the whole DIG Network. The reference node is:
https://rpc.dig.net
It is open, credential-free, and CORS-enabled (*) — any client, from a browser page to a CLI to another node, can call it directly. There is no API key and no account. Visiting it in a browser (GET https://rpc.dig.net/) returns a short intro page linking back to these docs; the interface itself is JSON-RPC 2.0 over POST (see Methods).
Point a client at it
Any read is one POST:
# liveness + advertised methods
curl -s https://rpc.dig.net -X POST -H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"dig.health"}'
# read a resource by retrieval key (sha256 of the URN), pinned to a generation root
curl -s https://rpc.dig.net -X POST -H 'content-type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"dig.getContent",
"params":{"store_id":"5b1f…e9","root":"latest","retrieval_key":"9f23…c1"}}'
