How this service works
Purchase order imports — Declared column projection: Declared column projection for Purchase order imports. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV declared column projection report.
Output
A declared column projection report for the submitted purchase order CSV, covering schema conformance, column type checks, numeric range violations, disallowed category values, cell length breaches, and a per-row or summary compliance status — up to 1000 rows processed per call.
Example use cases
Pre-import purchase order validation
“Before I load this purchase order CSV into our system, can you run a declared column projection check on it? The file has columns purchase_id, placed_on, vendor_id, ordered_units, and order_amount, vendors should only be group-a or group-b, order amounts must be between 0 and 500000, and I'm using comma as the delimiter.”
Vendor category compliance check
“I need to verify that all vendor IDs in my purchase order CSV are from the approved list — only group-a, group-b, and group-c are allowed. Can you run a column projection validation on it with a comma delimiter and flag anything that doesn't match?”
Order amount range enforcement
“Can you validate this purchase order import file and make sure the order_amount column stays between 1 and 999999? I also want to catch any cells longer than 200 characters. It's comma-delimited with the standard purchase_id, placed_on, vendor_id, ordered_units, order_amount columns.”

Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-csv-purchases-projection?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to validate a purchase order CSV against a declared column contract before importing it into a downstream system. It is purpose-built for purchase order data (purchase_id, placed_on, vendor_id, ordered_units, order_amount) and supports category allowlists, numeric range bounds, and cell length limits — all without sending data to external enrichment services. Prefer it over generic CSV validators when the domain is specifically procurement/purchase orders and you want a structured compliance report rather than a simple parse check.
