# APIKeys

Collecting data depends on the APIKeys of some websites.

> **Note**: The more apikey you have, the faster the BlockchainSpider!

You can configure APIKeys through `APIKEYS` in `settings.py`, and there are several default APIKeys provided by BlockchainSpider.

```python
APIKEYS = {
    "eth": [
        "7MM6JYY49WZBXSYFDPYQ3V7V3EMZWE4KJK"
    ],
    "bsc": [
        "NYYFYM2GM9FPCFETAMHHBXN67X7PU46EB9"
    ],
    "polygon": [
        "7BTFI86WFGAAD91X2AGSF7YWBWC3M4R39S"
    ],
    "heco": [
        "7SMM4F12EQRRGKYCN2VK6I48R7M8CFNE8R"
    ]
}
```

The website for registering APIKeys is as follows:

* **eth**: etherscan.io
* **bsc**: bscscan.com
* **polygon**: polygonscan.com
* **heco**: hecoinfo.com
