## 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 sna4an-wallet-validator-api-e434c708 -d '<json body>'
```

Example prompt: Can you check whether this Solana wallet address is valid before I send funds to it: 7xKXtg2CW87d97TXJSDpbD5jBkheTqA83TZRuJosgAsU?

## When to prefer this

Use this endpoint when you need to programmatically validate one or more crypto wallet addresses before executing a transaction, especially within the Solana ecosystem or when working with multi-chain address checks via RapidAPI-backed data. Prefer this over manual checks or general blockchain explorers when you need a structured, machine-readable validation response suitable for automated workflows.

## Known failure modes

- Invalid or malformed wallet address returns validation failure with error detail
- Unsupported blockchain network returns error or empty result
- Missing required path or params fields returns 400 bad request
- RapidAPI upstream timeout or rate limit causes 502 or 503 response
- Payment not received or insufficient USDC results in 402 payment required
