# Overview

Browse every error code the BeeL. API can return, organised by domain. Every error response includes a stable type URI pointing to its page here.

<Callout type="info" title="How error responses work">
Every API error response follows the RFC 9457 *Problem Details for HTTP APIs* contract. The `type` field is a URI that points to a stable documentation page right here — copy it from any error response into your browser to jump straight to the relevant entry.
</Callout>

**438 codes** across **15 domains**.
