## 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 klymax402-address-validator-api-79c04225
```

Example prompt: Can you check whether '742 Evergreen Terrace, Springfield, IL 62704' is a valid, properly formatted address and tell me if there are any issues with it?

## When to prefer this

Choose this endpoint when you need a quick, low-cost address parse-and-validate in a single call without managing API keys. It is ideal for agents that need structured address components plus a confidence score and issue list in one response, especially in workflows involving shipping, payments, or form validation.

## Known failure modes

- Empty or null address string returns an error or low-confidence result
- Completely garbled input may return valid=false with issues but no structured components
- Ambiguous addresses (e.g. missing zip code) may return partial components and reduced confidence
- Non-US addresses may not be parsed correctly if the service is US-focused
- Payment failure (402) if USDC balance is insufficient

## How this service works

One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.

## Output

Returns a JSON object with a boolean 'valid' field, a 'formatted' string of the corrected address, a 'components' object with parsed fields (street, city, state, zip, etc.), a 'confidence' score from 0 to 1, and an 'issues' array listing any detected problems such as missing components or formatting errors.
