> DeerAPI error codes and troubleshooting reference for API setup, billing, privacy, support, and troubleshooting.

## Overview

This page explains error codes and troubleshooting for DeerAPI users. Use it to verify configuration, understand expected behavior, and decide what to check before contacting support.

## Recommended checks

* Confirm that your base URL is `https://api.deerapi.com/v1` for OpenAI-compatible SDKs.
* Confirm that your request uses `Authorization: Bearer $DEERAPI_KEY`.
* Confirm that the model ID appears on the [live pricing page](https://api.deerapi.com/pricing).
* Keep request IDs from failed calls for troubleshooting.

## Production guidance

Use retries with exponential backoff for transient failures, monitor usage in the dashboard, and rotate API Keys after exposure.
