Troubleshooting API Issues Step by Step | Dataford Interview Questions

What are APIs and how would you fix different types of API issues, step by step?

Implement diagnose_api_issues(records, timeout_ms). Each record is a dictionary containing status, latency_ms, auth_valid, and body_valid. Return one dictionary per record with an issue category and an ordered list of remediation steps. Apply rules in this order: authentication, rate limiting, server failure, client failure, invalid response, timeout, then success. Each record must produce exactly one result.

Constraints

1 <= len(records) <= 10^4
0 <= latency_ms <= 10^9
0 <= timeout_ms <= 10^9
400 <= status <= 599 or 200 <= status <= 399
Each record contains exactly status, latency_ms, auth_valid, and body_valid
Each record produces exactly one result

Function Signature

def diagnose_api_issues(records, timeout_ms):
