<h2 id="overview">Overview<a class="headerlink" href="#overview" title="Permanent link">¶</a></h2>

<p>The <code>exceptions</code> module provides a set of pre-built HTTP exceptions and a FastAPI exception handler that formats all errors — including validation errors — into a uniform <a href="../../reference/schemas/#fastapi_toolsets.schemas.ErrorResponse"><code>ErrorResponse</code></a>.</p>
|
|
<h2 id="setup">Setup<a class="headerlink" href="#setup" title="Permanent link">¶</a></h2>

<p>Register the exception handlers on your FastAPI app at startup:</p>

<ul>

<li><a href="../../reference/exceptions/#fastapi_toolsets.exceptions.exceptions.ApiException"><code>ApiException</code></a> — all custom exceptions below</li>

|
|
<li><code>ResponseValidationError</code> — Pydantic response validation (422)</li>
|
|
<li><code>Exception</code> — unhandled errors (500)</li>
|

</ul>
|

<p>It also patches <code>app.openapi()</code> to replace the default Pydantic 422 schema with a structured example matching the <code>ErrorResponse</code> format.</p>
