# Token Pool Observations — Numeric Range Check

> Token Pool Observations — Numeric Range Check is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates numeric values in a token pool observations CSV table against declared minimum/maximum bounds and allowed category lists, returning a range-check report.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-numeric-range-check-342c5cfd -d '<json body>'
```

Example prompt: Check this token pool observations CSV for any numeric values outside the range 0 to 500000000, using a comma delimiter, and only allow pool addresses in categories 'group-a' and 'group-b': observation_id,observed_on,pool_address,liquidity_usd,volume_usd\nrecord-a,2026-01-01,group-a,10,2\nrecord-b,2026-01-02,group-b,20,3

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.01 USDC) automated range validation specifically for token pool observation data in CSV format, especially when you need to enforce both numeric bounds and categorical allowlists simultaneously without any external data enrichment. It is purpose-built for DeFi/token pool schemas (observation_id, observed_on, pool_address, liquidity_usd, volume_usd) and handles quoted cells natively.

## Known failure modes

- CSV exceeds 1000 rows — only up to 1000 rows validated
- CSV string exceeds 100,000 character limit — rejected
- Invalid delimiter specified — must be comma, semicolon, or tab
- Cell length exceeds max_cell_length limit — cell flagged or rejected
- Minimum value greater than maximum value — undefined behavior or error
- Malformed CSV with unclosed quotes — parse error

## How this service works

Token pool observations — Numeric range check: Numeric range check for Token pool 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 numeric range check report.

## Output

Returns a numeric range check report identifying which rows and cells contain values outside the declared minimum/maximum bounds, along with any category violations in the allowed_categories list. Up to 1000 rows are checked, with quoted cells supported.
