# Delx Commerce CSV Delimiter Detect

> Delx Commerce CSV Delimiter Detect is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Detects the most likely delimiter character (comma, tab, semicolon, pipe, etc.) used in a CSV text sample by scoring each candidate.

## Facts

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 delx-commerce-csv-delimiter-detect-483416aa -d '<json body>'
```

Example prompt: I have a chunk of raw text data and I'm not sure if it's comma-separated, tab-separated, pipe-delimited, or something else — can you detect the delimiter for me? Here's the text: 'name,age,city\nAlice,30,NYC\nBob,25,LA'

## When to prefer this

Choose this endpoint when you need a lightweight, zero-signup, pay-per-call delimiter detection with cryptographic verifiability (input hash, no-retention proof, zero external calls). Ideal for AI agents handling untrusted or unknown CSV formats in automated pipelines where auditability matters and you want to avoid spinning up a full data-processing service.

## Known failure modes

- Text too short or ambiguous to determine delimiter — scores may be tied or all zero
- Input exceeds 8192 character limit — request rejected
- Text contains no recognizable delimiter pattern — result may default to comma with low scores
- Malformed JSON body — 400 error
- Payment failure via x402 — 402 response before processing

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object containing a 'delimiter' field with the detected character, a 'scores' map showing confidence counts for each candidate delimiter (comma, tab, semicolon, pipe), an operation identifier, a status field ('pass'/'fail'), and an evidence block confirming no data retention and no external calls were made, plus an input SHA-256 hash for verifiability.
