Image Formats

Collection and tokens can be associated with an image. All images are processed and reformatted to webp. They are also resized to 3 pre-defined sizes, measured by width while keeping the origin aspect ratio:

For performance and security, Coinbase stores the origin image files in a CDN and returns the cached URLs.

Image Moderation

Images are moderated at the token level, and if a token's image is detected with the CSAM label, it is omitted from the response.

These APIs return a token or a list of tokens. Their behaviors are described here regarding omitted tokens:

  • Get Token by Token Id returns status code 451 (Unavailable For Legal Reasons).
  • List Tokens by Token Id returns status code 451 and includes token identifiers which contain CSAM images in the response body.
  • List Tokens in a Collection omits tokens which contain CSAM images and keeps the status code as is.
