How this service works
CSV Duplicate Rows: CSV Duplicate Rows finds duplicate normalized rows in bounded CSV text from bounded caller-supplied values without an external provider. Call CSV Duplicate Rows before an agent hands structured data or a batch plan to a downstream tool with a stricter contract. Returns the bounded transformation or validation finding with counts, normalized values, and a versioned result contract for CSV Duplicate Rows as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. Fir…
Output
Returns versioned deterministic JSON containing identified duplicate rows, their normalized values, occurrence counts, and a structured result contract indicating how many rows were duplicated and what they contained.
Example use cases
Pre-import data quality check
“Before I import this CSV into the database, can you scan it for duplicate rows and give me a count of how many are repeated? Here's the CSV: 'id,email\n1,a@b.com\n2,c@d.com\n1,a@b.com'”
ETL pipeline deduplication guard
“I'm about to hand this CSV batch to my downstream processing tool — can you first check it for any duplicate normalized rows so I know the data is clean? The CSV is: 'sku,qty,price\nABC,10,5.00\nDEF,20,3.50\nABC,10,5.00'”
Audit CSV export for repeated records
“I exported a report from our CRM and I suspect there are duplicate entries. Can you analyze this CSV text and list which rows appear more than once along with their counts? CSV: 'customer,region\nJohn,East\nJane,West\nJohn,East\nMark,North'”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/csv-duplicate-rowsWhen to prefer
Use this endpoint when you need a fast, deterministic, in-memory duplicate-row check on bounded CSV text before passing data to downstream tools with strict uniqueness contracts. Ideal for pre-validation in ETL pipelines, data import guards, and audit workflows where no external data store or large-scale processing is needed.
Side effects
- Text payload exceeds 8192 character limit, resulting in rejection
- Malformed or non-CSV text input causing parsing errors
- Empty text input returning no findings
- Non-tabular text causing ambiguous row detection
