## 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 crypto-wallet-address-classifier-29ecaf41 -d '<json body>'
```

Example prompt: Can you figure out which blockchain network this wallet address belongs to: '0x71C7656EC7ab88b098defB751B7401B5f6d8976F'?

## When to prefer this

Use this endpoint when you need to programmatically determine which blockchain network a wallet address belongs to before routing a payment, validating user input, or enriching transaction data. Prefer this over manual regex checks when you need to handle many different chain formats reliably at scale.

## Known failure modes

- Address string is empty or exceeds 120 characters — returns validation error
- Address format is unrecognized or ambiguous — may return low-confidence or unknown classification
- Malformed JSON body or missing required 'address' field — returns 400 bad request
- Network timeout or service unavailability — returns 5xx error

## How this service works

Guess which chain an address belongs to from its shape and encoding, without requiring the caller to know it up front. Returns the chain, format and address type, or nulls when nothing matches.

## Output

Returns the detected blockchain network and address type classification for the submitted wallet address string, indicating which cryptocurrency chain (e.g. Bitcoin, Ethereum, Tron, Solana) the address belongs to.
