# Verify the integrity of data downloads with our checksums API endpoint

[Checksum](https://en.wikipedia.org/wiki/Checksum) verification helps ensure the [data download](https://ipinfo.io/products/ip-database-download) is complete and matches the available data hosted on IPinfo servers.

Checksums support is helpful for our users in the following ways:

- Verify data integrity and completeness of data downloads.
- For compliance and security reasons, it is essential to make sure your IPinfo data downloads are not tampered with or corrupted in any way.
- You can use checksums as an easy verification method to avoid duplicate downloads by comparing the hash values of existing downloads.

## The checksum API endpoint

The checksum values are available on our website in the [data downloads section](https://ipinfo.io/account/data-downloads) and as an API endpoint. The checksum API endpoint:

```bash
https://ipinfo.io/data/<data_download_id>/checksums?token=$token

```

Essentially you have to just add the `/checksums` sub URL to the API download URL right before the token parameter declaration. You can check out our [data downloads filename reference](https://ipinfo.io/developers/database-filename-reference) table to check out our API URIs.

The API response output:

```json
{
  "checksums": {
    "md5": "ec1e0b806d09a4d367514fca3d7bae2e",
    "sha1": "488b50ea5c4cb97378bfcaa78b38305def65c65f",
    "sha256": "389294a764a8989d41d74608f1515133f3b910585ad6b75cfe53a81c82f7838f"
  }
}

```

## Comparing checksum values

The checksum API returns hash values in:

- MD5 (Message Digest Algorithm 5)
- SHA-1 (Secure Hash Algorithm 1)
- SHA-256 (Secure Hash Algorithm 256-bit)
