ASIC Straight-Line Daily Depreciation — Rolling Mean Report

Choose this endpoint when you need a smoothed, rolling-average view of straight-line daily depreciation across a batch of ASIC mining hardware assets, particularly when comparing multiple units with varying purchase prices, residual values, and useful lifespans. It is ideal for accounting, tax preparation, or fleet cost analysis workflows where raw per-unit depreciation figures are too noisy and a rolling mean provides a cleaner signal. Prefer it over single-asset depreciation calculators when you have 2–200 hardware rows and want a windowed statistical summary rather than individual depreciation figures.

• Fewer than 2 rows supplied — minimum array size is 2
• Window size exceeds number of rows — rolling mean cannot be computed
• purchase_usd or life_days set to zero or negative — schema exclusiveMinimum validation failure
• residual_usd exceeds purchase_usd — logically invalid but may not be schema-rejected
• More than 200 rows submitted — maxItems exceeded
• Missing required fields (purchase_usd, residual_usd, life_days) in any row — validation error
• Payment of 0.01 USDC not fulfilled — x402 payment required error
