# CSV Delimiter Detect

> 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.

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/csv-delimiter-detect
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability csv-delimiter-detect-450655d0 -d '<json body>'
```

Example prompt: Can you detect what delimiter is being used in this CSV snippet: 'name;age;city\nAlice;30;New York\nBob;25;London'?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
