## 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 moneytools-multi-chain-crypto-address-validator-4dc2ad3f
```

Example prompt: Can you check if bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh is a valid crypto address and tell me which blockchain network it belongs to?

## When to prefer this

Use this endpoint when you need to validate a crypto wallet address across multiple blockchains in a single call, especially when you need network identification alongside format validation. Ideal for pre-flight checks before sending crypto transactions to catch typos. Covers the widest range of chains including EVM, Bitcoin variants, Solana, Tron, Cosmos, TON, Litecoin, and Dogecoin in one API.

## Known failure modes

- Invalid or malformed address returns a validation failure response without charging
- Unrecognized address format returns unknown network
- Free tier exhausted (10/day) triggers HTTP 402 requiring x402 payment or API key
- Missing required 'address' query parameter returns an error
- Network connectivity issues may cause timeouts

## How this service works

Multi-chain address validator: Which network is this address for, and is it well-formed? EVM checksum, Bitcoin (legacy/P2SH/SegWit/Taproot), Litecoin, Dogecoin, Tron, Solana, Cosmos bech32, TON. Catches typos before sending. Free tier 10/day; then $0.001 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.001 USDC per call via x402 on Base. Run by MoneyTools.

## Output

A JSON object indicating whether the address is valid, the detected blockchain network, the address format/type (e.g. legacy, P2SH, SegWit, Taproot), checksum status for EVM addresses, and payment metadata including whether the free tier was used or a charge was made.
