Transactions for an Address from Algorand node

I tried the below address to fetch transactions from node and algoexplorer
Address -NJCLL5UPIZKXTHQ42M52B72DSO3PATJ2DEQOZQXJMWFMZPDLGUYV3PBJ5Q

• The transactions in the Algoexplorer are more then the transactions from node . Can any one let me know the reason for this .

curl -v http://127.0.0.1:8887/v1/account/NJCLL5UPIZKXTHQ42M52B72DSO3PATJ2DEQOZQXJMWFMZPDLGUYV3PBJ5Q/transactions -H “X-Algo-API-Token:xxx”

Your node, unless set to archival, only has visibility to the last 1000 blocks.

Also note that the above queries return only the last 100 transactions by default.
See parameter max in https://developer.algorand.org/docs/reference/rest-apis/algod/#get-v1accountaddresstransactions

@fabrice Thanks for the info but how do i get the count of transactions for a block so that i know what do provide the max parameter. For example if there are 1000 transactions and i want to pull out all of them so in max i need to provide 1000 but how do i know there are 1000 transactions.

That’s a good question. I don’t know of a better way than doing it manually right now:

• If you receive max transactions, you need to re-issue a query trying to get transactions from the last relevant block.
• In the unlikely case where more than max transactions are in the same block, the simplest way to get all of them might be to query the full block: https://developer.algorand.org/docs/reference/rest-apis/algod/#get-v1blockround

If you want to get the list of transactions of many different addresses, it is usually faster to query blocks directly https://developer.algorand.org/docs/reference/rest-apis/algod/#get-v1blockround and to filter the transactions you are interested in (or to store all the relevant transaction details for your application in a database that you can later query more easily).

@fabrice Thanks i think fetching the block info and pulling transactions would be the good one to proceed for getting all transactions.like below . please let me know if i am on the right track.
curl -v http://xxx/v1/block/4795723 -H "X-Algo-API-Token:"xxx"

1. I can pull the transactions as highlighted ?
2. As the block falls between 4500001 - 5000000 the reward for the block should be 72 but the reward is 103475. Could you help me understand the gap.

1. Yes, this is a good way to get transactions.
2. "reward":103745 means that if you had an account in the genesis block (round 0) with 1 Algo and you never made any transaction, then, at round 4795723, you would have 103745 microAlgos = 0.103745 Algos pending rewards for this account. See Reward, Rate ,Fraction and Proposer for details.

@fabrice - i think you mixed up rewards(block level) and pending rewards(account level).

1. Rate - is the reward for a particular block .Please correct if wrong.
2. For account level we have specific reward and pending rewards fields.

So as per the above question rate is “rate”:35999981 - i.e 35.999981 algos but as per the reward distribution block falls between 4500001 - 5000000 the reward for the block should be 72 but why is it 35.999981 algos .

Hi @debasish,

The distributed rewards for period 10 (blocks 4,500,000 to 4,999,999) are 18M Algos as per https://algorand.foundation/algo-dynamics. This corresponds to 18,000,000 / 500,000 = 36 Algos per round.
