## 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 wallet-balance-observations-category-allowlist-check-9a1b2c3f -d '<json body>'
```

Example prompt: Check my wallet balance observations CSV for any rows where the category isn't in the allowed list — my allowed categories are 'group-a' and 'group-b', and the CSV uses a comma delimiter with up to 1000 rows.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) automated check to confirm that categorical fields in a wallet balance CSV conform to a known allowlist, without needing external enrichment or complex transformation. Ideal for pipeline QA steps, compliance audits, or pre-submission data validation where the category dimension is the primary concern.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- CSV has fewer than 1 character — empty input error
- More than 1000 rows in CSV — only first 1000 processed or error returned
- Cell exceeds max_cell_length limit — validation error
- Invalid delimiter specified — must be comma, semicolon, or tab
- allowed_categories list exceeds 100 items — error returned
- Malformed CSV with unclosed quotes — parsing failure
