If yes, how can I see (using the API) that my daemon is fully synced?
The best way I can think of is querying the getlastblockheader and check the timestamp.
Code:
http://localhost:18081/json_rpc/getlastblockheader
Good idea! For the record, the call would require a post with:
Code:
{
"jsonrpc":"2.0",
"id":"yourid",
"method":"getlastblockheader"
}
"jsonrpc":"2.0",
"id":"yourid",
"method":"getlastblockheader"
}
For example:
Code:
curl -X POST http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"yourid","method":"getlastblockheader"}' -H "Content-Type: application/json" -H "Accept: application/json"
Works like a charm, much better than just reading the block chain height and comparing that to chainradar's one...
Thanks!
