# Custom Response Headers

We've added the following headers to our API's response, which reveal valuable information about your request and credit usage:

<table><thead><tr><th width="324">Header</th><th width="531">Description</th></tr></thead><tbody><tr><td>[PREFIX]-Client-Cookies</td><td>Javascript-generated cookies, after the target website is loaded</td></tr><tr><td>[PREFIX]-Scraped-Headers</td><td>The response headers of the scraped URL</td></tr><tr><td>[PREFIX]-Scraped-Resolved-Url</td><td>The final scraped URL (in case of redirects)</td></tr><tr><td>[PREFIX]-Call-Credit-Usage</td><td>The credit usage for the respective request</td></tr><tr><td>[PREFIX]-Current-Credit-Usage</td><td>Your total credit usage, after you make the request</td></tr></tbody></table>

Depending on the API you use, the prefix can be:

* WebScrapingAPI: `WSA`
* Amazon API, SERP API or other ecommerce APIs: `Searchdata`
