Errors and safe retries

Read the HTTP status and the JSON error field before retrying. Do not retry validation or authentication failures without correcting the request first.

HTTP	المدونة	What to do
400	`missing_parameter`	A required parameter is empty or absent. Check the parameter table for the endpoint.
403	`invalid_apikey`	The API key is unknown, expired or not authorized for the requested feature.
429	`too_many_requests`	Requests are arriving too quickly. Wait, then retry with exponential backoff.
500	`server_error`	The service could not complete the request. Keep the response and contact support if it persists.

Retry ruleRetry only transient 429 and 5xx responses. Start after 1 second, then back off to 2, 4 and 8 seconds.
