How to get Data Stored of Arweave

[stayForward09]

Hi, How are you? I'm Davee from ev3.xyz team, and we are going to add key metric- Data Stored of Arweave to our site https://depin.ninja/, especialyy, Data stored of Arweave like as https://viewblock.io/arweave/stat/cumulativeWeaveSize, So I tried to access api.viewblock.io/graphql, but I can't find where I should get API_KEY and query docs. Would you please help me to get relevant api and api documentation? Thanks.

Hey Davee!

No need for an API key, unless you want to get the data at extremely high frequency. Assuming a normal access pattern, you could just grab this from the headers of the current block from any Arweave gateway/node. Arweave.net is a big open one that is reliable (live for >5 years). g8way.io is also becoming popular but you can check out the full list on Viewblock for more options!

The route you need is GET /block/current, which will return a JSON encoding of the block. The field you want from the block is weave_size. Only thing to watch out for is that the JSON block encoding is relatively large (~300 KB or so).

Example with cURL:

sam@* ~ % curl https://arweave.net/block/current | jq .weave_size
"164241648689398"

Result is encoded as a BigNum string in preparation for it to increase 🫡.

Happy integrating! Sam

Thanks for your kind help @samcamwilliams I can get correct data from https://arweave.net/block/current, but the response is a bit large as you said. But I can't run this command; sam@* ~ % curl https://arweave.net/block/current | jq .weave_size Would you help me once more? Thanks.

I guess without prefix curl https://arweave.net/block/current | jq .weave_size

Hi @everyone @team First of all, thanks for your previous kind help, and may I have one more question? At this time, we'd like to add onchain revenue of Arweave to our site https://depin.ninja, and found the perfect reference is on https://viewblock.io/arweave/stat/txFees?time=month. Would you please help me to find relevant api to get this historical data? Thanks.
