It looks nice. A reliable service. I will use it in projects I develop with PHP. Thanks for announcing.

BLOCKSDK is a very good service. It is obvious that it is constantly developing.
I will definitely use it in my new projects. It is very successful compared to its alternatives.

The jig is up. You can stop posting these fake reviews for money

The number of reviews suddenly increases during the same time period
As the number of requests for bitcoins increases, we pay 0.0006 BTC each,
We checked the list of received emails and the subscriber IP bandwidth.

Confirmation result
The above 3 reviews are presumed to be written because one person wants to receive bitcoin several times.
The person who wrote the 3 reviews had the same IP band.
And only 1 out of 3 emails received event emails.
He cheated on us to pretend to be someone else to get more bitcoins.
We don't want reviews like this.

Because I want reviews from developers who have used them for development.
The content of the e-mail also contains a condition to use the API more than once.

And in fact, we only paid bitcoins to developers who have used the API directly.
And among the developers who learned about BLOCKSDK through this event, there are developers who still use it even after receiving bitcoins.

@OP: Good Service but I feel the free plans are very limited.

Why do you think the usage of the free plan is limited?
If you use the actual free plan personally, there is no case that it exceeds 2,000 times a day.

Great Job there @blocksdk. I didn't expect you would make the changes that quick. Thumbs up to you.
I was finally able to use your API to receive data through my Python code.

Thanks for the updated Python snippet.

Also, you should consider improvising your documentation.
For example : You said to call API using 2 methods but you didn't mention how to use them.
You should consider placing an example snippet/method on how to use the below 2 methods.

Quote

You can provide an API key to a REST API call in one of two ways
Preferred method: X-API-KEY via custom header
Convenient way: api_token via query string parameter

That actually explains a lot. I mean what else is there to explain? If you are someone starting as a new developer, you'd find it confusing because your basics about calling API's or passing headers and such are not that clear. The problem lies in your capability but not in the docs I suppose.

Isn't that's how it should be? Yes I am a beginner developer. The documentation should always be beginner friendly as it is now after the updates so that people like me could find it easy to start with.
Else the developers could create their own custom API and never use services like these at all.

P.S : I was able to create a custom header and fetch data through blocksdk API too.

Lastly, I tried accessing your API but was getting '403 Forbidden' error. Not sure what's wrong.

The 403 error is probably coming from the absence of an API key in your request. You just fetch

Code:

https://FULL-URL-OF-API?api_token=abcdefg12345678

where you substitute my gibberish string with your API key. Basically the api_token parameter comes at the end of the URL.

The first method involves sending a header in your request. A header is a key/value pair that is sent to the server that gives it the same info as the "? =" parameters. All programming languages have a URL fetch function that can send arbitrary headers, and they are standard learning material in web development courses

So I did try your API and my experience was not so good. After signing up I was logged in blocksdk and I was keeping on searching for API documentation for a while but didn't get it anywhere.
Later when I was logged of, I noticed that there was an API documentation. I wonder why you didn't consider placing a link to API documentation after logging in since that is what users would do.

Hello @blocksdk

There are some cosmetic issues on your website, you should first consider rectifying those issues at the earliest.
For example: The login page has a spelling mistake on the Login button.

The form on register page should have fields marked as mandatory and optional. Here I didn't enter the Company details but was still able to signup.

Though your service is good, developers hate it when a website has bugs/cosmetic issues.
You should consider hosting a contest for bugs/issues and you will get promotion for your site while getting to know all the bugs/issues.

I have signed up and got my API key. Will check how it works and post a review later.

1.Price proposal
I think it's a good idea.
In order to acquire more customers, all BLOCKSDK members can receive 1:1 chat development support,
If you need a custom API, we will develop it further.

2.createwallet API (Wallet KEY)
Only the keys of one-way encryption values are stored on the server, and no one can know the keys unless you are the wallet creator.
In other words, even if a hacker hacks the database, the key is not known.

3.Store transactions, blocks and addresses in the block explorer
MYSQL and our Bitcoin node server are synchronized in real time.
The execution speed of the SQL statement to fetch specific transaction information is 0.001 seconds

It's great that you are offering a free way to query address and transaction data without requiring a full node, but I have a suggestion for your pricing structure.

First, you can use Basic as your home-use or a kind of personal plan but for advanced developers, like some of the devops services I can think of (Github, Travis, et al have this kind of plan). You can make it affordable to those individuals like at $40/month with Basic'a quota limits.

Second you can merge Beta and Pro into a single business plan with Pro's pricing and limits but I also recommend significantly increasing the rate limit for this business plan. In general businesses have more cash to spend for buying things like this. You can even add live telephone support within business hours to make it more attractive to them.

Last you can replace Production with an enterprise plan with custom limits but enterprises need to contact you about their requirements. The advantage is you can charge them thousands of dollars a month for accommodating their possibly high requirements, way higher than the $500/month your biggest plan charges.

The pricing stuff is just my opinion based on what I've seen other companies do, you're also free to use your own kind of pricing.

Also I have a question about your createwallet APi calls. How much security is put in place to protect the private keys that are in the wallet (which I assume are created on your servers)? Since you are returning seed phrases, are you using Electrum as the backend?

Finally we've been discussing the last few days on how transaction, block and address data in a block explorer can be queried so much faster from a database than from a node, so would you mind telling us how you store all this data server-side?
