Example prompt: Can you run an ordered trend analysis on our checkout payment failure share? Here are the records — 4 failures out of 100 attempts, 6 out of 110, 5 out of 105, 7 out of 115 — I want to see if the failure rate is trending up.

## When to prefer this

Choose this endpoint when you have a sequential, ordered series of retail checkout payment attempt and failure counts and need a bounded trend analysis of the failure share over time. It is purpose-built for checkout payment failure rate trending in retail contexts and returns a structured report for up to 200 records at very low cost ($0.01 USDC). Prefer this over general statistics APIs when you specifically need trend direction on payment failure share without requiring live rates, platform access, or order execution.

## Known failure modes

- Fewer than 2 rows supplied — minimum input requirement not met
- payment_attempts value of 0 — excluded by exclusiveMinimum constraint
- failed_attempts exceeds payment_attempts — logically invalid ratio
- More than 200 rows supplied — exceeds maxItems limit
- Malformed row objects with missing required fields payment_attempts or failed_attempts
