Order Imports CSV Header Contract Check

Choose this endpoint when you need a lightweight, deterministic CSV schema validation specifically for order import files with columns like order_id, ordered_on, customer_id, gross_amount, and item_count. It is ideal for pre-import quality gates, vendor file audits, or pipeline guards where you need to check header contracts and value constraints without external enrichment or full data processing. Prefer it over general-purpose CSV validators when your use case matches the orders domain and you need a per-call, pay-as-you-go model at $0.01 USDC.
