To check the meta of lots of files, submit an API search and then scroll through results.

Get meta via HTTP

Simply send an HTTP request for the file, with ?info appended to the URL. It will return the entire file meta in JSON, including meta from your original file.


Scroll towards the end to see this meta:

    "tags": [
    "description": "Sleeping tiger",
    "title": "Example image",
    "product": {
      "id": "TIG001",
      "name": "Tiger close-up",
      "brand": "Animal Prints",
      "category1": "Animals",
      "category2": "Big cats"

You can also request that data in JSONP format. Add &callback=abc to the URL.


Get meta via CSV

It's easy to export a list of files as a CSV from your account. This is a good way to get meta for a large number of files. The CSV will contain columns for title, description, tags and any custom meta. Product meta can be added - please ask our customer success team if you need this.

Get meta via

Simply go to the file preview page for any file in your account at Meta data is shown to the right.

Sanitise your input

If you're adding meta via a script and cannot trust the source, you should sanitise the inputs, following standard best-practice. For example, strip content that contains any of the following:

  • <script
  • onclick
  • onload
  • onmousemove etc.

Try the API

A relatively quick way to try the API is with Sirv's Postman API collection. In Postman, go to the section Sirv REST API > Files and you will see options to set or get meta description, title, tags, product meta and approval meta. In the Params section, set the path to your Sirv image; in the Body section, set the meta values you wish to apply.

API limit

Your account can use a finite number of API requests per hour. Meta requests count towards your total hourly limit. Your current usage is shown on the Usage page of your account.

Enterprise Business Trial Free
API requests / hour 14,000 7,000 7,000 500

If you reach your limit, pause until the hourly limit refreshes. Every API request you submit will return a response containing the number of remaining requests and the refresh time.

It will help you to troubleshoot any issue if you save each API response in a log.
