# Status Codes & Errors

The `AI Parser` returns standard HTTP status codes for every request. The table below lists each code, what it means and what to do next.

<table><thead><tr><th width="214.18511962890625">Code</th><th width="276.4815673828125">Meaning</th><th width="261.76214599609375">What to do</th></tr></thead><tbody><tr><td><code>200 OK</code></td><td>Success</td><td>N/A</td></tr><tr><td><code>202 Accepted</code></td><td>Request accepted, processing asynchronously</td><td>Poll <code>GET /parsers/&#x3C;PARSER_ID></code> until status <code>FINISED</code></td></tr><tr><td><code>204 No Content</code></td><td>Success, no response body (returned when <strong>deleting</strong> a parser)</td><td>N/A</td></tr><tr><td><code>400 Bad Request</code></td><td>Malformed JSON or missing required field</td><td>Check the request body. Ensure <code>api_key</code>, <code>name</code> and <code>urls</code> are present on <code>POST /parsers</code></td></tr><tr><td><code>401 Unauthorized</code></td><td>Invalid <code>api_key</code></td><td>Chek your API Key in the <a href="https://dashboard.scraperapi.com/home">dashboard</a></td></tr><tr><td><code>402 Payment Required</code></td><td>Credits exhausted</td><td>Upgrade your plan or <a href="https://dashboard.scraperapi.com/contact-support">contact support</a></td></tr><tr><td><code>404 Not Found</code></td><td><code>parser_id</code> doesn't exist</td><td>Verify the id with <code>GET /parsers</code></td></tr><tr><td><code>500 Internal Server Error</code></td><td>Extraction failed</td><td>Retry the request. Try adding <a href="/pages/u1uiJWhomIMzqF7f2egv#supported-scraperapi-parameters">additional parameters</a>. If extraction keeps failing, <a href="https://dashboard.scraperapi.com/contact-support">contact support</a></td></tr><tr><td></td><td></td><td></td></tr></tbody></table>

Separate from the HTTP statis codes, here are the possible values for the `status` field returned by `GET /parsers/<PARSER_ID>`

<table><thead><tr><th width="359.6666259765625">Status</th><th>Meaning</th></tr></thead><tbody><tr><td><code>GENERATING</code></td><td>The parser is being generated. Parsing <strong>won't</strong> work yet</td></tr><tr><td><code>FINISHED</code></td><td>Parser is ready to use</td></tr><tr><td><code>FAILED</code></td><td>Generation failed. Check <code>error</code> field for details</td></tr></tbody></table>

{% hint style="info" %}
Here are some  common causes for  `status: "FAILED"`&#x20;

* Example URLs were inaccessible or blocked
* Example URLs were from a different URL Type (category, product, search, etc.)
* The domain may require JS Rendering and `render=true` was not set inside `scraper_params`
