CSV Delimiter Detect
x402
CSV Delimiter Detect is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Detects and scores the most likely delimiter character(s) in a CSV text snippet, returning counts and normalized confidence values.

How this service works
CSV Delimiter Detect: CSV Delimiter Detect scores common delimiters from bounded CSV text from bounded caller-supplied values without an external provider. Call CSV Delimiter Detect 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 Delimiter Detect as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base.…
Output
A versioned deterministic JSON object containing scored and ranked delimiter candidates (e.g. comma, semicolon, tab, pipe), their occurrence counts, normalized confidence values per delimiter, and a versioned result contract envelope for downstream interoperability.
Example use cases
Pre-parse delimiter sniffing for ETL pipeline
“Before I feed this CSV chunk into the pipeline, can you figure out whether it's comma-separated, semicolon-separated, or tab-separated? Here's the first few rows: 'id|product|price\n1|Widget|9.99\n2|Gadget|14.99'”
Validating user-uploaded CSV format
“A user just uploaded a CSV file and I'm not sure what delimiter they used — can you analyze this sample and tell me which separator character it's most likely using: 'sku,description,qty\nABC,Blue Widget,10\nDEF,Red Gadget,5'?”
Downstream tool contract preflight check
“I need to pass this delimited text to a strict downstream parser — can you score the possible delimiters in this excerpt so I know what separator to tell the tool to expect: 'city country population\nParis France 2161000'?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/csv-delimiter-detectWhen to prefer
Use this endpoint when an agent needs to programmatically determine the delimiter of an unknown CSV or delimited text sample before passing it to a stricter downstream parser or ETL tool. Prefer it over manual heuristics or full CSV parsers when you need a lightweight, deterministic, auditable scoring result without retaining the input data. Ideal as a preflight check in agentic data pipelines where the delimiter contract must be explicit.
Side effects
- Text exceeds 8192 character limit — request rejected
- Ambiguous or empty input returns low-confidence scores across all delimiters
- Non-delimited or free-form text may produce unreliable scores
- Payment failure via x402 prevents execution
- Malformed JSON request body returns validation error
