## 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-tokenized-stock-anti-scam-check-bc389364 -d '<json body>'
```

Example prompt: Is this Solana token mint address 'Xsc9qvGR1efVDFGLrVsmkzv3qi45LTBjeUKSPmx9qEh' a legitimate official tokenized stock from xStocks or Ondo, or could it be a scam imitation?

## When to prefer this

Use this endpoint when you need to determine whether a specific Solana token mint is an officially sanctioned tokenized stock from known issuers (xStocks/Backed, Ondo) versus a scam or copycat token. Ideal for DeFi platforms, wallets, portfolio tools, or trading bots that need real-time anti-fraud checks on tokenized equities before displaying or transacting with them.

## Known failure modes

- Invalid or malformed Solana mint address returns an error
- Unknown mint not matching any known tokenized stock issuer returns a 'POSSIBLE IMITATION' verdict
- Network or RPC issues querying Solana may cause timeouts
- Newly issued legitimate tokens not yet indexed may be flagged as unverified

## How this service works

Anti-scam check for tokenized stocks on Solana: tells whether a token mint was issued by an official issuer (xStocks/Backed, Ondo) via its mint authority, or is a POSSIBLE IMITATION posing as one.

## Output

Returns a JSON object with the mint address, token name, symbol, issuer name, a verdict ('official' or 'POSSIBLE IMITATION'), a Solscan explorer link, a plain-English explanation of the verdict, the token supply, the issuance authority public key, and the list of verified issuers checked against.
