<p>I am trying to incorporate bitcoin in one of the applications and want to integrate the REST API which exposes all the public information.</p>
<p>I tried using <code>https://chain.api.btc.com/v3/block/3</code> but upon multiple requests, it starts to error out with message &quot;Do not abuse the api&quot;.</p>
<p>Kindly provide the reference to API which I can use</p>

I am trying to incorporate bitcoin in one of the applications and want to integrate the REST API which exposes all the public information.

I tried using `https://chain.api.btc.com/v3/block/3` but upon multiple requests, it starts to error out with message "Do not abuse the api".

Kindly provide the reference to API which I can use

Note: Tried `https://testnet.blockexplorer.com/api` as well but doesnt work. Even the link on `https://github.com/blockchain/api-v1-client-python#request-limits-and-api-keys` leads to error page on web

**Tags:** api, block

If you plan to using any API extensively I suggest installing [bitcoin core](https://bitcoin.org/en/bitcoin-core/) and using [RPC](https://bitcoincore.org/en/doc/0.21.0/) provided.

I don't know if there is an unlimited and free service as you looking for, but you can easily setup your own Bitcoin node and make all the calls you want, in addition it helps the Bitcoin network to be healthier and safer.
