Data Cloud API (Deprecated)

​

What is Data Cloud?

The Chainbase Data Cloud lets you run your low-latency queries through an endpoint to leverage all our indexed datasets for your custom needs. Chainbase’s Data Cloud is a fully managed online data warehouse service for Web3 developers. Developers can query the data warehouse through the API to access our datasets with zero infra cost. And the Data Cloud’s scalable, distributed analytical data engine and intelligent data modeling allow you to query terabytes of data in seconds.

​

Quickstart

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
}'
