How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object containing: normalized CSV string, parsed headers array, array of valid rows, row count, array of rejected rows with reasons, and a list of validation issues found in the data. Also includes a receipt with payment confirmation, execution metadata, and a SHA-256 hash of the result.
Example use cases
Pre-import data quality check
“I have this raw CSV data with a header row and comma delimiters that I want to load into our database — can you validate it and tell me which rows are malformed or have issues before I import it?”
Tab-separated log file cleanup
“This is a tab-separated log export with no header row — can you normalize it and flag any rows that don't conform so I can see what needs to be fixed?”
Semicolon-delimited European export validation
“I got a semicolon-delimited CSV from our European supplier with a header row — can you parse and validate it, and give me back the clean normalized version along with any rows that were rejected?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/csv_normalize_validate/invokeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call CSV normalization and validation step — especially in automated pipelines where data quality must be checked before downstream processing. At $0.01 USDC per call it is cost-effective for single-file or per-record validation without needing a full ETL platform. Supports comma, tab, and semicolon delimiters with optional header detection.
Side effects
- Empty or missing text input returns validation error
- Text exceeding 65536 character limit is rejected
- Invalid delimiter value outside allowed enum causes schema error
- Malformed JSON request body returns parse error
- Payment failure results in 402 response before execution
