## 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-csv-column-projection-validator-ecc85ed5 -d '<json body>'
```

Example prompt: Validate this wallet balance CSV for me — it has columns for observation_id, observed_on, wallet_address, native_balance, and token_balance, and the allowed categories are group-a and group-b. Make sure balances are between -1000000000000 and 1000000000000 and cells are under 1000 characters.

## When to prefer this

Use this endpoint when you need a lightweight, pre-configured column projection validator specifically shaped for wallet balance observation CSVs with fields like observation_id, observed_on, wallet_address, native_balance, and token_balance. It is ideal when you want to verify a declared CSV contract without external enrichment, need fast per-call validation at low cost ($0.01 USDC), and your data fits within 1000 rows. Prefer alternatives if you need schema inference, large-batch processing beyond 1000 rows, or validation of unrelated CSV formats.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows submitted — only first 1000 may be processed or error returned
- Invalid delimiter used (not comma, semicolon, or tab) — parse error
- Cell exceeds max_cell_length limit — validation failure reported
- Value outside minimum/maximum range — flagged in report
- Category value not in allowed_categories list — flagged as violation
- Malformed or unquoted CSV causing parse failure — error response

## How this service works

Wallet balance observations — Declared column projection: Declared column projection for Wallet balance observations. Validate a declared CSV table contract, up to 1000 rows. Quoted cells supported; no external enrichment. Specialised preset in a shared 50-profile, 20-operation engine. 0.01 USDC includes one CSV declared column projection report.

## Output

Returns a declared column projection report confirming whether the submitted CSV conforms to the expected wallet balance observation schema — including column presence, data type adherence, value range compliance, category membership, and cell length constraints — across up to 1000 rows.
