# Token Holder Observations — Spreadsheet Formula Flags Validator

> Token Holder Observations — Spreadsheet Formula Flags Validator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Validates a CSV table of token holder observations by detecting spreadsheet formula injection flags, supporting up to 1000 rows with configurable delimiter, value bounds, and allowed category lists.

## 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-holder-observations-spreadsheet-formula-flags-validator-fc6da546 -d '<json body>'
```

Example prompt: Can you check this token holder observations CSV for spreadsheet formula flags? The table has columns observation_id, observed_on, token_address, holder_count, and circulating_tokens, comma-delimited, with holder counts ranging from 0 to 1000000, and allowed categories group-a and group-b.

## When to prefer this

Choose this endpoint when you specifically need to detect spreadsheet formula injection flags (cells starting with =, +, -, @, etc.) in a token holder observations CSV, especially when working within a structured data pipeline that requires a pre-validated, contract-compliant CSV before downstream spreadsheet import. It is purpose-built for the token holder observation schema (observation_id, observed_on, token_address, holder_count, circulating_tokens) and is not a general-purpose CSV linter or blockchain data enrichment tool.

## Known failure modes

- CSV exceeds 100,000 character limit — request rejected
- More than 1000 rows in the CSV — validation not performed
- Cell value exceeds max_cell_length setting — flagged or rejected
- Delimiter mismatch causes incorrect parsing — incorrect column mapping
- Numeric value outside specified minimum/maximum range — flagged as invalid
- Category value not in allowed_categories list — flagged as disallowed
- Malformed or unquoted CSV with embedded commas — parse error

## How this service works

Token holder observations — Spreadsheet formula flags: Spreadsheet formula flags for Token holder 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 spreadsheet formula flags report.

## Output

Returns a formula flags report for the submitted CSV table, identifying cells or rows containing potential spreadsheet formula injection patterns (e.g. cells starting with =, +, -, @). The report covers up to 1000 rows and respects the configured delimiter, value bounds, allowed category list, and max cell length constraints.
