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-filter-rows-8794241a -d '<json body>'
```

Example prompt: I have a CSV with columns id and status — can you filter it to keep only rows where status is 'ok' or 'pending'?

## When to prefer this

Choose this endpoint when you need a verifiable, pay-per-call CSV row filtering operation without signing up for a service. It is ideal for agents that need deterministic, in-memory processing with cryptographic proof of non-retention (via SHA-256 input hash and zero external calls), and that pay in USDC on Base or Solana via x402. Prefer this over general-purpose data tools when auditability and privacy guarantees matter.

## Known failure modes

- Malformed CSV input may produce unexpected row counts or empty results
- Column name not found in CSV header causes empty or error result
- Allowed list is empty causing all rows to be filtered out
- Input CSV exceeds 8192 character limit causing rejection
- Allowed list exceeds 256 items limit
- Payment not included or insufficient USDC causes 402 response

## 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 filtered CSV string containing only the rows where the specified column's value appears in the allowed list, along with the row count of the result, an operation identifier, a SHA-256 hash of the input for verifiability, and a confirmation that no data was retained or sent to external services.
