# Vextorium Crypto Address Validator

> Vextorium Crypto Address Validator is a paid API for AI agents from api.vextorium.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-10-13).

Validates and classifies a cryptocurrency address by format, network, type, and encoding across EVM, Bitcoin, Solana, Litecoin, Dogecoin, Tron, and Cosmos — computed locally without external calls.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 vextorium-crypto-address-validator-c3ccab83 -d '<json body>'
```

Example prompt: Before I send the payment, can you check whether bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq is a valid Bitcoin address and tell me what type it is?

## When to prefer this

Choose this endpoint when you need fast, local, offline-style validation of crypto addresses across multiple blockchains without relying on a third-party node or RPC call. Ideal for pre-payment sanity checks, form validation, or when you need to detect the chain and address type from an unknown address string. Covers a broader range of chains (EVM, Bitcoin variants, Solana, Litecoin, Dogecoin, Tron, Cosmos) than most single-chain validators.

## Known failure modes

- Empty or missing 'direccion' field returns a validation error
- Unrecognized or malformed address string returns valida: false with null type/network fields
- Addresses from unsupported chains (e.g. Cardano, XRP) may return valida: false rather than an error
- Checksums that fail EIP-55 validation for EVM addresses return valida: false

## How this service works

Detect and validate a crypto address before sending funds: EVM (EIP-55 checksum), Solana, Bitcoin (legacy, P2SH, SegWit, Taproot), Litecoin, Dogecoin, Tron and Cosmos bech32, with its type and network. Computed locally.

## Output

Returns a JSON object with: 'valida' (boolean indicating if the address is valid), 'direccion' (the input address echoed back), 'red' (the network, e.g. 'Bitcoin mainnet'), 'tipo' (address type, e.g. 'P2WPKH (SegWit nativo)'), 'familia' (address family, e.g. 'Bitcoin'), and 'codificacion' (encoding scheme, e.g. 'bech32').
