## 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 swogeagentic-stock-token-authenticity-checker-fc3b858e -d '<json body>'
```

Example prompt: Before I trade this token, can you check if contract address 0xabc123... on Robinhood Chain is actually the official NVDA stock token or just a copycat using the same ticker?

## When to prefer this

Use this endpoint specifically when interacting with stock-linked tokens on Robinhood Chain (chain ID 4663) and needing to confirm contract authenticity before any trade, transfer, or automated interaction. It is purpose-built for the Robinhood Chain ecosystem where official and copycat stock tokens coexist under identical tickers — generic contract decoders or block explorers won't give you an official-vs-copy verdict.

## Known failure modes

- Unknown or unsupported ticker symbol returns no match or error
- Invalid contract address format causes a validation error
- Contract not yet indexed results in inconclusive or empty response
- Payment failure (insufficient USDC balance or wrong chain) blocks the call
- Network timeout from Railway-hosted service under load

## How this service works

Use this before touching a stock token on Robinhood Chain (NVDA, TSLA, SPY...): it tells whether a contract is the official Robinhood Stock Token or a copy using the same ticker. Price: $0.006 in USDC on Base or Solana, or $0.02 in USDG or $SWOGE on Robinhood Chain (tool price + settlement cost, minimum $0.02).

## Output

Returns whether the given contract address is the officially recognized Robinhood Stock Token for the specified ticker symbol, or an unofficial copy/impostor using the same ticker. Includes a verdict distinguishing authentic from counterfeit contracts.
