2xx Success

4xx Client Error

5xx Server Error

Dxspot uses standard HTTP status codes to indicate the result of a request:
2xx — success,
4xx — error in request data/permissions,
5xx — server-side error (rare).

Some 4xx responses include a short
error.code and message for programmatic handling.

Handling recommendations

Log the HTTP status and the response body.
For 429 and temporary 5xx, use retries with exponential backoff (backoff + jitter).
Validate required parameters before sending the request.

Code	Title	Description
200	OK	Everything worked as expected.
400	Bad Request	Invalid request (often a required parameter is missing).
401	Unauthorized	No valid token/key provided.
402	Request Failed	Parameters are valid, but the operation was not completed.
403	Forbidden	Insufficient permissions to perform the request.
404	Not Found	The resource does not exist.
409	Conflict	Conflict with the current state (duplicate, inconsistency, etc.).
424	External Dependency Failed	A failure in an external dependency prevented the request from being completed.
429	Too Many Requests	Rate limit exceeded — reduce frequency and apply backoff.
500, 502, 503, 504	Server Errors	Server-side error. Retry later (with backoff).

Information summary

Dxspot uses standard HTTP codes. 2xx — success; 4xx — validation/permission/client errors; 5xx — server errors (rare). Handled 4xx responses include an error code and message. For 429 and temporary 5xx, use exponential backoff with jitter. Always log the status and response body.
