Example prompt: I have 4 periods of retail return data — recovered values of 600, 660, 600, 660 and returned goods costs of 1000, 1100, 1000, 1100 — can you calculate the adjacent period changes in my returned goods value recovery rates?

## When to prefer this

Choose this endpoint when you have raw retail return records (recovered value and returned goods cost per period) and need a quick, low-cost adjacent period change report without requiring platform access, live pricing feeds, or order execution capabilities. Ideal for periodic batch analysis of up to 200 return records at $0.01 per call.

## Known failure modes

- Fewer than 2 rows supplied — minimum of 2 records required
- returned_goods_cost of exactly 0 is rejected (exclusiveMinimum:0)
- More than 200 rows submitted — maxItems limit exceeded
- Non-numeric values in recovered_value or returned_goods_cost fields
- Payment failure or insufficient USDC balance for the $0.01 per-call fee
