  42. <h1>Copyvio Detector API</h1>
  43. <p>This is the first version of the <a href="//en.wikipedia.org/wiki/Application_programming_interface">API</a> for <a href="${request.script_root}">Earwig's Copyvio Detector</a>. It works, but some bugs might still need to be ironed out, so please <a href="https://github.com/earwig/copyvios/issues">report any</a> if you see them.</p>
  44. <h2>Requests</h2>
  45. <p>The API responds to GET requests made to <span class="code">https://tools.wmflabs.org/copyvios/api.json</span>. Parameters are described in the tables below:</p>

  191. "error": {
  192. "code": <span class="resp-dtype">string</span> <span class="resp-desc">error code</span>,

  235. <p>In the case of <span class="code">action=compare</span>, <span class="code">best</span> will always contain information about the URL that was given, so <span class="code">response["best"]["url"]</span> will never be <span class="code">null</span>. Also, <span class="code">sources</span> will always contain one entry, with the same data as <span class="code">best</span>, since only one source is checked in comparison mode.</p>

  254. <h2>Etiquette</h2>
  255. The tool uses the same workers to handle all requests, so making concurrent API calls is only going to slow you down. Most operations are not rate-limited, but full searches with <span class="code">use_engine=True</span> are globally limited to around a thousand per day. Be respectful!
  256. <h2>Example</h2>
