## 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-sort-rows-fa040c4f -d '<json body>'
```

Example prompt: Sort this CSV by the 'price' column in descending order: 'id,name,price\n3,Widget,9.99\n1,Gadget,24.50\n2,Doohickey,4.75'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call, no-signup CSV row sort with cryptographic proof of no data retention — ideal for agents handling sensitive tabular data that must not be persisted, or for pipelines that require verifiable, auditable transformations at minimal cost ($0.001 USDC per call).

## Known failure modes

- Malformed or unparseable CSV input returns an error status
- Specified column name not found in CSV headers causes failure
- Input exceeding 8192 character limit is rejected
- Boolean descending field sent as string may cause validation error
- Empty CSV input with no rows returns row_count of 0

## 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 the sorted CSV as a string under result.csv, the number of data rows under result.row_count, a status field ('pass'), an operation identifier, and an evidence block confirming no data retention and zero external calls, along with an input SHA-256 hash for verifiability.
