## 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-spreadsheet-formula-flags-validator-4e949ca5 -d '<json body>'
```

Example prompt: Can you check this wallet balance CSV for spreadsheet formula flags? It has columns observation_id, observed_on, wallet_address, native_balance, and token_balance, with comma delimiters — flag any cells that look like formula injections and validate balances between -1000000000000 and 1000000000000.

## When to prefer this

Choose this endpoint when you need to validate a wallet balance CSV specifically for spreadsheet formula injection risks before opening it in Excel, Google Sheets, or similar tools. It is purpose-built for the wallet balance observation schema (observation_id, observed_on, wallet_address, native_balance, token_balance) and supports category allowlisting and numeric range checks in a single call. Prefer this over generic CSV validators when the domain is crypto wallet data and formula injection security is the primary concern.

## Known failure modes

- CSV exceeds 1000 rows — validation refused
- CSV string exceeds 100,000 character limit — request rejected
- Invalid delimiter value (must be comma, semicolon, or tab)
- Cell content exceeds max_cell_length limit — flagged or truncated
- Minimum value greater than maximum value — configuration error
- Malformed CSV (unbalanced quotes, encoding issues) — parse error
- Empty CSV string (minLength:1 not met) — validation error

## How this service works

Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV spreadsheet formula flags report.

## Output

A CSV spreadsheet formula flags report listing any cells in the submitted wallet balance table that contain potential spreadsheet formula injection patterns (e.g. values starting with =, +, -, @), along with overall contract validation status indicating whether the CSV conforms to the declared structure within the specified row, value, and category constraints.
