## 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 zaref-uif-calculator-72562a07 -d '<json body>'
```

Example prompt: What would my monthly UIF contribution be if I earn R28,000 gross per month in South Africa — show me both the employee and employer portions?

## When to prefer this

Choose this endpoint when you need programmatic, cited UIF contribution calculations for South African payroll processing, HR tools, or financial planning apps. Prefer over manual lookup tables when you need machine-readable output and always-current statutory rates.

## Known failure modes

- Missing or invalid income parameter returns 400 error
- Income above statutory UIF ceiling silently capped at maximum contribution
- HEAD method returns no response body — use GET for actual calculation results
- Service unavailable or payment not processed returns non-200 status

## How this service works

South African reference data as clean, cited JSON: fuel prices, interest rates, FX and bond yields, tax tables, tariffs, wages and grants, live government tenders and crypto prices, plus calculators. Built for AI agents and applications.

## Output

Returns a JSON object with the computed UIF contribution amounts, including the employee deduction, employer contribution, and combined total, based on the provided income figure and current South African UIF rate (1% each side, capped at the statutory ceiling).
