## 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 agentstall-za-south-african-id-number-validator-e345a3c4
```

Example prompt: Can you check whether the South African ID number 8001015009087 is valid, and tell me what gender, date of birth, and citizenship status it encodes?

## When to prefer this

Use this endpoint when you need to validate and decode a South African 13-digit ID number specifically — it applies the SA government's Luhn algorithm and parses the embedded date-of-birth, gender, and citizenship fields. Prefer it over generic checksum validators because it returns decoded semantic fields meaningful for KYC, compliance, and eligibility checks in a South African context.

## Known failure modes

- ID number fewer or greater than 13 digits returns validation failure or error
- Invalid Luhn checksum returns valid:false with no decoded block
- Missing 'id' query parameter returns 402 or 400 error
- Unpaid call (no x402 payment header) returns HTTP 402 with PAYMENT-REQUIRED header
- Non-numeric characters in ID string may cause parse error

## How this service works

South African ID number validation: checks a 13-digit SA ID number (date of birth, citizenship digit and Luhn checksum) and decodes date of birth, age, gender and citizenship status. Structural check only, with no Home Affairs lookup; the number is not stored. Useful for KYC and onboarding forms and for catching typos.

## Output

A JSON object with a 'valid' boolean indicating whether the ID number passes the Luhn check and structural validation, plus a 'decoded' object containing gender (male/female), dateOfBirth (YYYY-MM-DD), ageYears (integer), and citizenship ('SA citizen' or 'permanent resident') if valid.
