best BTC API? (dev)

[jordimetil]

i'll make this clear and short, i wanna know which is most comprehensive API for Bitcoin, made for developing?

[BitMaxz]

Why did you look for other sources of APIs the Bitcoin core or full node itself has RPC API you don't need to look for other sources unless you don't want to run a full node.

But if you still insist on looking for them I have a list of a good source for Bitcoin development that I think you can use for developing check this link below.

Thanks a lot

FYI, even if OP or someone else doesn't want to run their own full node, they could use service (such as getnodes.io getblock.io) which offer Bitcoin Core API.

At a glance, the list looks decent although it doesn't contain any service which designed to accept Bitcoin payment (such as Coinbace Commerce).

More of a comment to the OP but it also matters what you are doing with it.

You need the best car.....
Are you doing around town deliverers with it?
Are you doing long road trips with it?
Do you just need it to go a few miles to and from work?
Do you need to have your large family in it comfortably?
and so on.

The answer to what car depends on it's use.

There are a bunch of APIs that work well, but there are some better then others for certain tasks.

i understand your point, sorry i didn't show my intentions more clear. anyways, i want best BTC API to make live bitcoin price tracker for my website.

You may want to look at what Bitcoinity.org has to offer https://bitcoinity.org/markets/webmasters

If you just want free api which allows you display crypto prices, use coingecko's free api (but there are some limitations) you can also pay for better one.




here is code
js

Code:

import React, { useEffect, useState } from 'react';
import './CryptoPriceTracker.css';
import Modal from 'react-modal';

const CryptoPriceTracker = () => {
  const [prices, setPrices] = useState([]);
  const [selectedCoin, setSelectedCoin] = useState(null);
  const [search, setSearch] = useState('');

  useEffect(() => {
    fetch('https://api.coingecko.com/api/v3/coins/markets?vs_currency=usd')
      .then(response => response.json())
      .then(data => setPrices(data))
      .catch(error => console.error('Error fetching prices:', error));
  }, []);

  const handleSelectCoin = (coin) => {
    setSelectedCoin(coin);
  };

  const handleSearchChange = (event) => {
    setSearch(event.target.value);
  };

  const closeModal = () => {
    setSelectedCoin(null);
  };

  const filteredCoins = prices.filter((coin) =>
    coin.name.toLowerCase().includes(search.toLowerCase())
  );

  return (
    <div className={`crypto-price-tracker-container ${selectedCoin ? 'blurred' : ''}`}>
      <h1 className="text-hackerGreen font-pixel">Crypto Price Tracker</h1>
      <input
        type="text"
        className="search-input"
        placeholder="Search for a cryptocurrency"

      />
      <ul className="coin-list">
        {filteredCoins.map((coin) => (
          <li
            key={coin.id}
            className="coin-item"
            onClick={() => handleSelectCoin(coin)}
          >
            <img src={coin.image} alt={coin.name} className="coin-image" />
            <span>{coin.name}</span>
          </li>
        ))}
      </ul>
      {selectedCoin && (
        <Modal
          isOpen={!!selectedCoin}
          onRequestClose={closeModal}
          contentLabel="Crypto Info"
          className="crypto-modal"

This code requires react to install

upd
You can also make as chart, this time i used coincap free api.



requires libraries to display that chart also.

Why did you look for other sources of APIs the Bitcoin core or full node itself has RPC API you don't need to look for other sources unless you don't want to run a full node.

FYI, even if OP or someone else doesn't want to run their own full node, they could use service (such as getnodes.io) which offer Bitcoin Core API.

Those online providers of RPC APIs have a serious limitation. Because they only allow so many (lat's say X) amount of calls a day, it means you cannot use their APIs for building a transaction database which would otherwise let you work offline, because that requires literally millions of RPC calls which are way above what any provider is willing to allow.

[DaveF]

Agree with @aliveNFT coingecko is probably one of the better ones. And if you are just displaying the BTC price and updating every few minutes you will never run into any API call limitations.
Keep in mind what you are seeing at that point is a general idea of the price averaged across many exchanges. You can also get the price from a single exchange as most of them offer that too.

As of this moment
i.e. Average BTCprice according to coingecko is: $69313 BTC price at Coinbase is: $69378 so you can give interesting comparisons.

Yes.. Unfortunately, in order to get the highest quality API for processing a bunch of calls per second and whatever it is in real time, it is necessary to throw out a considerable amount per month.
But I think in the case of the OP, he just needed an api to display the value of BTC. I think that free ones will be enough for him.

Does this getnodes.io work for you? Can you access the site?
I can't seem to access the site and my AV Kaspersky blocking it I also tried accessing it through other devices but it seems it's down.
Anyway, OP does not look exactly what we pointed to.

i understand your point, sorry i didn't show my intentions more clear. anyways, i want best BTC API to make live bitcoin price tracker for my website.

Now, it's clear well, that the links that I provided are for blockchain development so it won't fit if you are building a live Bitcoin price tracker.

The best API for price tracking is already mentioned above Coingecko and another one is Coinmarketcap but if you still looking for another price tracker with API check this one for Bitcoin only.

Code:

https://blockchain.com/ticker

You're right. But when i made that reply, i didn't know what kind of data OP wants or how frequent he need to obtain it.

I also cannot access getnodes.io, although i'm sure i accessed it normally few months ago.

Sniped

Was there no dependency installed
Maybe the package.json will just be fine  to install ....
Or he can just make use of it's own ui along with the api because  I think  he only wants to use it in his project, generally it's a cool idea with the css for easy testing  
He can also use it without  installing react too he just need to declear those state use a required var.. + promise + functions =>(Js)

Getnodes.io doesn't have any IP address attached to it. Are you sure that you wen't trying to go to getblock.io or maybe bitnodes.io? Because both of them work on my end.

The best API for price tracking is already mentioned above Coingecko and another one is Coinmarketcap but if you still looking for another price tracker with API check this one for Bitcoin only.

Personally, the most responsive price API I've seen so far is the Binance API, and you can couple that with any fiat currency exchange rate API in order to get things like BTC-USD price and stuff like that. But it needs an API key for both sites. That's fine though because you can just cache the fiat data and update it every 24 hours or at midnight.

Thanks for the reminder, i actually trying to say getblock.io. Looks like i forget their actual domain since i never use their service and i primarily remember they offer node API.

disagree. It doesn't support balance on external address which you most probably will need. bcoin library has it

That could be solved by also running self-hosted block explorer or Electrum server. Besides, bcoin development is very slow these days where one of bcoin member state they're yet to support new features[1].

still supported. that's where i've used it. i can go without taproot to be fair . support on commercial platform means they do not have any real flaws for now
