Write a Load Testing Script

Write a load testing script for [API / ENDPOINT / APPLICATION].

Target: [URL AND ENDPOINT DESCRIPTION]
Tool: [K6 / ARTILLERY / LOCUST / JMETER — or recommend]
Authentication: [BEARER TOKEN / API KEY / NONE]

Test scenarios to cover:
1. Baseline — steady load ([X] users for [Y] minutes)
2. Ramp-up — gradually increase from 0 to [X] users over [Y] minutes
3. Spike test — sudden burst of [X] users for [Y] seconds
4. Stress test — push until failure or defined limit

For each scenario:
- Script code with comments
- Metrics to track (p95 latency, error rate, throughput)
- Pass/fail thresholds to define
- How to interpret the results

Include: how to run the test, how to view results, and what to do if the service is degrading.
