# Errors RateParity uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an error that failed given the information provided (e.g., a required parameter was omitted, etc.). Codes in the 5xx range indicate an error with RateParity's servers. | 200 - OK | Everything worked as expected. | | ---------------------------------- | ------------------------------------------------------------------------------------------------ | | 400 - Bad Request | The request was unacceptable, often due to missing a required parameter. | | 401 - Unauthorized | No valid API key provided. | | 402 - Request Failed | The parameters were valid but the request failed. | | 403 - Forbidden | The API key doesn't have permissions to perform the request. | | 404 - Not Found | The requested resource doesn't exist. | | 409 - Conflict | The request conflicts with another request (perhaps due to using the same idempotent key). | | 429 - Too Many Requests | Too many requests hit the API too quickly. We recommend an exponential backoff of your requests. | | 500, 502, 503, 504 - Server Errors | Something went wrong on RateParity's end. | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.rateparity.com/errors.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
