Bitcoin address balance checker.

[examplens]

Well, I am surprised, there is an option for many major currencies.
It seems does not work for me. I just send some BTC, but I did not receive any notification.
The bot also does not read my regular balances on the added address.

First you need to give them the address and then they will ask you to chose which coin and you chose Bitcoin to activate the notifications. Mine s working fine. Reveived three notificaions for two tx. My guess is one tx was rebroadcased because the fees was low or I would have two notifications for two tx.

I guess remove the bot and then add it again. Hopefully it will work.

Of course, I know that I need to add address and connected them with the proper coin. Done it all, but nothing after the first transaction.
I added some other coins, I will follow how it works with them.
Is it your address segwit?

And again, it will be limited to 5k requests/month until/unless people get more interest in this and I try to find a different solution.

Are you using a block explorer API to obtain the balance? Or do you have a DB with each address’ balance?

I would think you would hit your 5k request/month limit fairly quickly considering that each time this page is viewed, it is querying your site 6 times.

I was discussing creating an API for someone who wanted to be able to query the balance of any address a few months ago. He ended up ghosting me (and I strongly suspect creating additional accounts asking for help with various aspects of this project) before we could arrange for escrow to hold payment. I had created basic pseudo code for importing address balances into a DB. Querying a DB shouldn’t be difficult and it shouldn’t be difficult to monitor the bitcoin price on an ongoing basis.

The limit is only to grab the value in USD of an address or the amount in BTC worth of a certain amount (/price/ endpoint). All of these features use BitcoinAverage's API which is limited. I could easily cache the price, like Loyce said, which is what I will probably do soon.

For the balance, there is no limit. And no, I don't save any balance of the addresses. When the image is generated, my server pings Blockstream's explorer API and get the balance of the address (where there is no visible limit).

Most major exchanges have API endpoints that you could connect to that display the “last” price on their exchange. I also believe futures exchanges have endpoints that return the reference index price. I wouldn’t think they would have limits you would reasonably hit.

Yes, it this one: 3Covid19s5zLNzQHGGLBeqkizwApUb19bj
An hour ago there was another TX and I got notified too. Not sure what is going on in your side.

Edit:

One thing I noticed is that it gives more than one notification for some tx. I am still new and may be need more time to figure it out.

It works, finally. But it seems only to an incoming transaction. I tested with sending BTC and there aren't notifications. I think the problem is here.
I must confirm one great stuff here, I receive some tokens on my ETH address and notifications working with them. It is better than Etherscan, which have options only for Ethereum.

Excuse my fat finger :-p
In my case I received notification for both incoming and outgoing tx. Strange things are happening in your side :-D

I have not tested it with any other coin though.

@TryNinja: is this no longer working? I mean: can you fix it?

Sorry, it went down when my VPS shit the bed and I totally forgot to put it back online.

I didn't see this thread when it came out, however, I'd just like to make mention of one tool I use for posting the price of bitcoin or the amount of bitcoin in terms of a given fiat as exampled in this quote from my Lightning Loans thread:

Mainnet LN loans are also down to BTC 0.00002 and BTC 0.0000202 repayment if more than 24 hours lent.

At one point in the past, the images stopped working.  I was able to get them going by adding an "S" to the http at the beginning of the URL i.e. https

The above are configurable either on the website https://youmeandbtc.com/bitcoin-converter or tweeking the code.

(and yes, it doesn't check balances, but it can complement your project never-the-less)
