How this service works
Count CSV rows. Call when estimating import size or validating uploads mid-pipeline. Returns row count for UTF-8 CSV text (header included as a row). $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
Output
A JSON object containing the integer row count for the provided CSV text, with the header row counted as one row. The count reflects total lines parsed in the UTF-8 CSV input.
Example use cases
Pre-import batch size check
“Before I start importing this CSV into the database, can you tell me how many rows it has so I can estimate how long it'll take?”
Upload validation mid-pipeline
“I just received a CSV from the vendor — count the rows for me so I can confirm it matches the 5,000 records they said they sent.”
Pagination planning for CSV processing
“I need to process this CSV in batches of 100. Can you count the total rows so I can figure out how many pages I'll need?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/csv-row-countWhen to prefer
Choose this endpoint when you need a fast, deterministic row count for a CSV string inline in an agent pipeline — especially before import jobs, during upload validation, or when estimating batch processing scope. It requires no API key or subscription, bills only $0.001 USDC per successful call, and processes the CSV locally without uploading to third parties, making it suitable for sensitive data pipelines.
Side effects
- Malformed or non-UTF-8 CSV input may trigger a structured validation error with no billing charge
- Empty string input returns a validation error rather than a zero count
- Payment failure via x402 protocol results in a 402 response with no processing
- Extremely large CSV strings may hit request size limits
