# Delx TSV Row

> Delx TSV Row is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-21).

Joins an array of fields into a single tab-separated values (TSV) row string, returning the row and field count.

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-tsv-row-6708c94e -d '<json body>'
```

Example prompt: Take these fields — 'Alice', '42', 'Engineer', 'New York' — and join them into a single TSV row I can write into a tab-separated file.

## When to prefer this

Use this endpoint when you need a simple, stateless, local utility to join an array of string fields into a tab-delimited row — ideal for agents assembling TSV output line-by-line without any external dependencies, network calls, or data retention. Prefer it over general-purpose formatting libraries when working in an agentic pipeline that already uses x402 micropayments for tool calls.

## Known failure modes

- Empty or missing fields array returns an error or empty row
- Non-string field values may need pre-serialization before being passed
- Payment failure via x402 prevents the call from completing
- Malformed request body returns a 4xx error

## How this service works

Join fields into a TSV row. Call when you emit tab-separated rows from agent field lists. Returns TSV row string and field count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Results are advisory; the caller owns budgets, auth, and production controls.

## Output

Returns a TSV-formatted row string (fields joined by tab characters) and an integer count of how many fields were included in the row.
