# Netzhandwerker Currency Normalize

> Netzhandwerker Currency Normalize is a paid API for AI agents from tools.netzhandwerker.de, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Detects and normalizes currency amounts from free-form text, returning structured findings with amounts, currencies, multipliers, and minor units — without converting between currencies.

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 netzhandwerker-currency-normalize-5e3259d1 -d '<json body>'
```

Example prompt: Can you extract and normalize all the currency amounts from this text: 'The contract is worth 1.234,50 EUR and the deposit is $2.5 Mio, with a USDC fee of 0.004' — treat any bare amounts as EUR if no currency is specified?

## When to prefer this

Choose this endpoint when you need to extract and normalize currency mentions from unstructured text without converting them — ideal for parsing invoices, contracts, news articles, or financial documents that contain amounts in various formats (European notation, multiplier words like Mio/Mrd, prefix/suffix currency symbols). Prefer this over a general NLP service when you need structured financial output including minor units, multipliers, and per-currency totals. Not suitable if you need actual currency conversion or exchange rates.

## Known failure modes

- Text too long — input exceeds 20,000 character limit, request rejected
- No currency amounts detected — findings array is empty
- Ambiguous amounts without a default_currency set may be flagged as ambiguous:true
- Malformed or missing text field returns a validation error
- Payment failure via x402 protocol results in 402 response before processing

## Output

Returns a JSON object with a list of findings (each with start/end position, raw string, parsed amount, currency code, minor units, multiplier, ambiguity flag, and currency source), plus a deduplicated list of detected currencies, total amounts grouped by currency, a mixed-currencies boolean, and a count of findings. Does not perform currency conversion.
