How this service works
Invoice imports — Header contract check: Header contract check for Invoice 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 header contract check report.
Output
A structured report confirming whether the CSV header contract is valid, including details on any column name mismatches, disallowed category values, out-of-range numeric fields, cell length violations, or parsing errors found within the supplied rows.
Example use cases
Pre-import invoice file validation
“Before I push this invoice CSV to our accounting system, can you validate the header contract? The file uses comma-separated values, columns are invoice_id, issued_on, account_id, net_amount, tax_amount, and the only valid account categories are group-a and group-b.”
Catch schema errors in finance pipeline
“My automated invoice import keeps failing — can you run a header contract check on this CSV to see if there's a column mismatch or invalid category value? The delimiter is a semicolon and amounts should be between -1000000 and 1000000.”
Validate third-party invoice data
“I just received an invoice CSV from a vendor and need to confirm it matches our declared import contract before loading it. Please check the headers and make sure all rows — up to 1000 — conform, with comma as the delimiter and allowed categories of group-a and group-b.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-bx-csv-invoices-schema?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, purpose-built CSV contract check specifically for invoice import files with the standard fields (invoice_id, issued_on, account_id, net_amount, tax_amount). It is ideal as a lightweight pre-import gate to catch header mismatches, invalid categories, and numeric range violations before committing data to a downstream system. Prefer it over generic CSV validators when you need invoice-domain-aware validation with configurable category allowlists and numeric bounds.
Side effects
- CSV exceeds 100,000 character limit — rejected with size error
- Invalid delimiter specified — validation fails to parse
- CSV contains no rows or is empty — returns empty/invalid contract error
- Cell values exceed max_cell_length — flagged as contract violation
- Numeric values outside declared minimum/maximum bounds — flagged as range errors
- Category values not in allowed_categories list — flagged as invalid
- Malformed CSV (unmatched quotes, bad encoding) — parse error returned
