# CSV Trim Cells

> CSV Trim Cells 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).

Trims surrounding whitespace from every cell in a caller-supplied CSV string, returning normalized values with counts and a versioned result contract.

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-trim-cells-f03db25c -d '<json body>'
```

Example prompt: Can you trim all the surrounding whitespace from every cell in this CSV before I send it to the downstream tool? Here's the text: 'Name , Age , City\nAlice , 30 , New York '

## When to prefer this

Use this endpoint when you need a fast, deterministic, stateless way to strip surrounding whitespace from all cells in a CSV string before passing structured data to a downstream tool or system with a strict schema contract. Prefer it over custom code when running in an agent context where reliability, versioned output contracts, and zero-retention processing matter.

## Known failure modes

- Input text exceeds 8192 character limit — returns validation error
- Malformed or non-CSV input may produce unexpected trimming results
- Empty input string returns empty or minimal result
- Network or payment authorization failure returns 402 or connection error

## How this service works

CSV Trim Cells: CSV Trim Cells trims surrounding whitespace from every bounded CSV cell from bounded caller-supplied values without an external provider. Call CSV Trim Cells 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 Trim Cells as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, s…

## Output

Returns a versioned deterministic JSON object containing the trimmed CSV text with all cell whitespace removed, counts of how many cells were modified, normalized cell values, and a versioned result contract indicating the transformation outcome.
