Example
Query the hashes of the last 3,000 blocks in Ethereum and the number of transactions in each block:
curl -X "POST" "https://api.chainbase.online/v1/dw/query" \
-H 'X-API-KEY: YOUR-API-KEY ' \
-H 'Content-Type: application/json; charset=utf-8' \
-d $'{
"query": "select number, transactions_count from ethereum.blocks order by number desc limit 3000;"
}'
If there are more than 1000 rows, you need to paginate through thetask_id and page to get all the results:
curl -X "POST" "https://api.chainbase.online/v1/dw/query" \
-H 'X-API-KEY: YOUR-API-KEY ' \
-H 'Content-Type: application/json; charset=utf-8' \
-d $'{
"task_id": "xxxxxxxxxxxxxxxxxxxxx",
"page": 2
}'
