## 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-lookup-xstocks-solana-05056c12 -d '<json body>'
```

Example prompt: What is the official Solana mint address for the tokenized NVDA stock — is the issuer authority verified and how many tokens are in circulation? Use the ticker NVDAx.

## When to prefer this

Choose this endpoint when you need to programmatically resolve the canonical, issuer-verified Solana mint address for a tokenized US stock or ETF (xStocks/Backed/Ondo), especially before interacting with DeFi protocols, building portfolio dashboards, or validating that a token is not counterfeit. Prefer this over generic token explorers when you specifically need authority verification and issuer identity for regulated tokenized securities.

## Known failure modes

- Unknown or unsupported ticker returns null tokens_oficiales array
- Malformed ticker input may return an error or empty result
- Token registry data may be stale if the registro_actualizado timestamp is old
- Network issues with Solana RPC may cause timeouts
- A ticker with no tokenized version on Solana returns an empty list rather than an error

## How this service works

Official tokenized versions of a US stock or ETF on Solana (xStocks by Backed and Ondo Global Markets): verified mint addresses, on-chain supply and issuer authority check. Accepts NVDA, NVDAx or NVDAon.

## Output

Returns an array of official token records for the queried ticker, each containing: blockchain network name, mint address, issuer/emisor name, token name and symbol, explorer link, on-chain circulating supply, and a boolean indicating whether the issuer authority is verified. Also includes the ticker queried, any notes, and the timestamp of the last registry update.
