## When to prefer this

Choose this endpoint when you need to apply the precise Dutch statutory WIK sliding-scale collection cost formula (Besluit vergoeding voor buitengerechtelijke incassokosten) to a principal amount, especially when you need legally defensible output. Prefer it over manual calculation to avoid bracket arithmetic errors, and over generic fee calculators when Dutch law compliance is required.

## Known failure modes

- Missing required 'amount' query parameter returns a 400 error
- Amount not matching pattern (e.g. more than 2 decimal places or non-numeric) returns a validation error
- Amount of zero or negative value may return minimum fee of EUR 40 or an error
- VAT parameter value other than 'true' or 'false' returns a validation error
- Payment not made (x402) results in 402 Payment Required response

## How this service works

Dutch statutory extrajudicial collection costs (buitengerechtelijke incassokosten, WIK scale, Besluit vergoeding voor buitengerechtelijke incassokosten art. 2): 15/10/5/1/0.5% over the principal in brackets, minimum EUR 40, maximum EUR 6,775, optional 21% VAT when the creditor cannot reclaim VAT. Use it to compute the legally allowed collection fee on a Dutch claim.

## Output

Returns the calculated extrajudicial collection fee broken down by WIK tariff brackets (15%/10%/5%/1%/0.5%), the total fee capped at EUR 6,775 and floored at EUR 40, and optionally the 21% VAT surcharge and grand total — all in EUR.
