## 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-category-allowlist-check-7a08daee -d '<json body>'
```

Example prompt: Check my token pool observations CSV for category compliance — I only want to allow the categories 'group-a', 'group-b', and 'group-c'; flag any rows where the pool_address doesn't match those.

## When to prefer this

Choose this endpoint when you need a lightweight, purpose-built allowlist check specifically for token pool observation CSVs with a pool_address or category column, without needing external enrichment or complex schema validation. It is ideal for automated data pipeline QA steps where you want a cheap ($0.01 USDC), fast pass/fail report on category compliance before ingesting or publishing DeFi pool data.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows in CSV — rows beyond limit may not be validated
- allowed_categories list exceeds 100 entries — request rejected
- Cell length exceeds max_cell_length — parsing error
- Malformed CSV (unclosed quotes, wrong delimiter) — parse failure
- Empty CSV input — validation cannot proceed
