|
"\n",
|
||||||
|
"You will need a Etherscan api key to proceed. The free api key has 5 calls per seconds quota.\n",
|
||||||
|
"\n",
|
||||||
|
"The loader supports the following six functinalities:\n",
|
||||||
|
"* Retrieve normal transactions under specifc account on Ethereum Mainet\n",
|
||||||
|
"* Retrieve internal transactions under specifc account on Ethereum Mainet\n",
|
||||||
|
"* Retrieve erc20 transactions under specifc account on Ethereum Mainet\n",
|
||||||
|
"* Retrieve erc721 transactions under specifc account on Ethereum Mainet\n",
|
||||||
|
"* Retrieve erc1155 transactions under specifc account on Ethereum Mainet\n",
|
||||||
|
"* Retrieve ethereum balance in wei under specifc account on Ethereum Mainet\n",
|
||||||
|
"\n",
|
||||||
|
"\n",

"If the account does not have corresponding transactions, the loader will a list with one document. The content of document is ''.\n",
|
||||||
|
"\n",
|
||||||

"You can pass differnt filters to loader to access different functionalities we mentioned above:\n",

|
"\n",
|

"All functions related to transactions histories are restricted 1000 histories maximum because of Etherscan limit. You can use the following parameters to find the transaction histories you need:\n",
|
||||||
|
"* offset: default to 20. Shows 20 transactions for one time\n",
|
||||||
|
"* page: default to 1. This controls pagenation.\n",
|

|
"* start_block: Default to 0. The transaction histories starts from 0 block.\n",

"* end_block: Default to 99999999. The transaction histories starts from 99999999 block\n",
|
||||||
