The number of requests per second is limited to 5 request per second. There is not paid service yet.

The Etherscan Ethereum Developer APIs are provided as a community service and without warranty, so please just use what you need and no more. They support both GET/POST requests and a rate limit of 5 requests/sec.

To use the API service please create a FREE Api-Key Token from within the ClientPortal->MyApiKey area which you can then use with all your api requests. Either a link back or mention that your app is "Powered by Etherscan.io APIs" would be appreciated.

  • As far as I know infura doesn't have limits source. I found etherscan very useful and simple, I created a wrapper for python that you can find here. I didn't know about blockcypher until now, I took a quick look at it and it looks amazing, thanks for that. If this answered your question please accept the answer.

  • in first infura hasn't limit but it has limits now. limit is 100K req/day for free users. blockcypher has limit too. blockcypher has 3 req/sec and 200 req/hr limits.
