Newbie- API to get Ethereum's latest blocks

Question

I am looking for an ethereum api to get the N latest blocks. I will use javascript (react) to make the requests.

I have looked into https://etherscan.io/apis#blocks but it has nothing to do with what I need (at least what I see there).

Also https://github.com/ethereum/wiki/wiki/JSON-RPC seems complicated to use as I will have CORS issues (?). And I don't see what I need there either

Thank you

Answer 1

I believe this might be something you're looking for?

This returns latest-n blocks of the ethereum network. It's currently limited to 100 blocks.

Answer 2

With Amberdata.io it's really easy you just:

curl -X GET \
  'https://web3api.io/api/v2/blocks?size=10' \
  -H 'x-api-key: '

And it will give you the last 10 blocks. You can try it out here.

Answer 3

You can use this one from The Graph and change first 10 to value of N.

query last10Blocks { blocks(first: 10, orderBy: BlockNum, orderDirection: desc) { BlockNum } }
