Example prompt: Can you calculate the checkout payment failure share for my retail store — we had 100 payment attempts and 4 of them failed?

## When to prefer this

Use this endpoint when you need a quick, single-shot calculation of checkout payment failure share from raw retail attempt counts, without requiring platform access, live payment data, or order execution capabilities. Ideal for analytics pipelines, reporting dashboards, or agent workflows that need to compute failure rates on-demand from supplied figures (up to 200 records).

## Known failure modes

- payment_attempts is zero or not provided — violates exclusiveMinimum constraint, returns validation error
- failed_attempts exceeds payment_attempts — logically invalid input, may return an error or unexpected result
- Values exceed maximum threshold of 1,000,000,000,000 — returns validation error
- Missing required fields — returns schema validation error
- Service unavailability — returns HTTP error or timeout
