How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object indicating whether the CSV has any duplicate rows (unique: true/false), a list of the duplicate row indices, an operation identifier, an advisory status, and an evidence block containing the SHA-256 hash of the input and confirmation that no data was retained and no external calls were made.
Example use cases
Pre-import data quality check
“Before I import this CSV into our database, check it for duplicate rows so I don't create redundant records — here's the CSV content: 'id,email\n1,a@b.com\n2,c@d.com\n1,a@b.com'”
Spreadsheet deduplication audit
“I exported this spreadsheet as CSV and I suspect some rows got duplicated — can you scan it and tell me exactly which row numbers are copies? CSV: 'product,price\nWidgetA,9.99\nWidgetB,14.99\nWidgetA,9.99\nWidgetC,4.99'”
ETL pipeline validation
“As part of our data pipeline, check whether this CSV batch has any duplicate rows and flag the row numbers if so — the CSV text is: 'order_id,customer\n101,John\n102,Jane\n101,John'”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/csv-duplicate-rows?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, pay-per-call, no-signup check for duplicate rows in CSV text with verifiable privacy guarantees (no data retained, input hash provided as proof). Ideal for AI agents operating in automated ETL pipelines, data validation workflows, or one-off data quality checks where a full data platform integration is unnecessary. Prefer this over general-purpose code execution when you need a deterministic, auditable result with a cryptographic evidence trail.
Side effects
- Input text exceeds 8192 character limit — returns an error or truncation
- Malformed or non-CSV text provided — may produce unreliable or empty duplicate detection
- Payment not completed via x402 protocol — request blocked before processing
- Empty input string — may return unique:true with no duplicate rows listed
