## 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 token-pool-observations-blank-row-report-414988d4 -d '<json body>'
```

Example prompt: Can you check my token pool observations CSV for any blank rows? Here's the data with columns observation_id, observed_on, pool_address, liquidity_usd, volume_usd — use comma as the delimiter and flag any completely empty rows you find.

## When to prefer this

Choose this endpoint when you need to specifically identify and report blank or empty rows in a token pool observations CSV before ingestion, processing, or reporting. It is purpose-built for the token pool observations schema (observation_id, observed_on, pool_address, liquidity_usd, volume_usd) and supports quoted cells and configurable delimiters. Prefer this over generic CSV validators when working with DeFi/liquidity pool data pipelines that require a lightweight, cost-effective ($0.01 USDC) blank-row quality gate.

## Known failure modes

- CSV exceeds 100,000 character limit — returns error
- CSV has fewer than 1 character — returns validation error
- Delimiter not one of comma, semicolon, or tab — returns schema error
- Row count exceeds 1000 — may be rejected or truncated
- Cell length exceeds max_cell_length setting — flagged or rejected
- Invalid numeric bounds (minimum greater than maximum) — returns error
- Malformed CSV that cannot be parsed — returns parse error
