# Token Swap CSV Numeric Type Validator

> Token Swap CSV Numeric Type Validator is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Validates numeric columns in a token swap CSV dataset, checking that values fall within allowed types, ranges, and category constraints — up to 1000 rows.

## 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-swap-csv-numeric-type-validator-a643a7e8 -d '<json body>'
```

Example prompt: Can you run a numeric type check on this token swap CSV — it has columns like swap_id, executed_on, pool_address, input_tokens, and output_tokens — and flag any rows where the numeric values look wrong or out of range?

## When to prefer this

Choose this endpoint when you need a lightweight, per-call numeric type validation of a token swap CSV before importing it into a database or analytics pipeline — especially when you want to enforce a declared column contract (numeric ranges, allowed categories) without spinning up a full ETL stack. It is purpose-built for DeFi/swap datasets and costs only $0.01 USDC per check.

## Known failure modes

- CSV exceeds 1000 rows — only first 1000 rows validated
- CSV string empty or malformed — returns parse error
- Delimiter mismatch causes all rows to fail parsing
- Values exceed max_cell_length — cell flagged or truncated
- min > max configuration yields vacuous range — all numeric values fail
- Non-UTF-8 or binary content causes ingestion failure

## How this service works

Token swap imports — Numeric type check: Numeric type check for Token swap imports. 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 type check report.

## Output

A numeric type check report identifying which rows and cells in the token swap CSV fail to meet numeric type requirements, range constraints (min/max), and allowed category checks — returned as a structured validation result for up to 1000 rows.
