I have an Insight API Server running, it's fully synced and working. I would like to get a json to receive every tx within a block.

On https://github.com/bitpay/insight-api it says I have to use:

Transactions by Block
  /insight-api/txs/?block=HASH
  /insight-api/txs/?block=00000000fa6cf7367e50ad14eb0ca4737131f256fc4c5841fd3c3f140140e6b6

For example we take block #301453. This block has 725 transactions.

https://insight.bitpay.com/block/00000000000000004dff81aadf782cceb8a2d082f0f255472791c8bb2984e958

If I use the api to get the json file with this link:

http://localhost:3001/insight-api/txs/?block=00000000000000004dff81aadf782cceb8a2d082f0f255472791c8bb2984e958

... then it shows the first 10 transactions only (numbers 0 - 9). But there are 725 tx in this block.

It looks like the number 10 are those addresses are the first who are displayed. If i scroll further down, more transactions appear. But why does the json request only show 10 txs?

How can I get ALL transactions in this block - as the documentations mentions?

You have two options.

Option 1:
The returned json includes a "pageTotal":'some number'.
You can create a for-loop to loop through all the pages with API calls.

Let assume there are two pages aka "pageTotal":2

To fetch the first page, append parameter [&pageNum=0] to the end
Example usage:

http://localhost:3001/insight-api/txs/?block=00000000000000004dff81aadf782cceb8a2d082f0f255472791c8bb2984e958&pageNum=0

To fetch the second page, add param [&pageNum=1]
Example usage:

http://localhost:3001/insight-api/txs/?block=00000000000000004dff81aadf782cceb8a2d082f0f255472791c8bb2984e958&pageNum=1


Option 2:
Modify transactions.js , 'var pageLength' on Line 253.
The default is 'var pageLength = 10;'
Unsure if there are consequences by doing this, but I assume it should be fine.

  • Thanks! I changed "var pageLength" to 50000. This should list 50.000 tx and should last a while. :) I think option two is the faster solution. – A.c Dec 21 '17 at 23:42
