## 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 tereno-rwa-market-guard-c091488a -d '<json body>'
```

Example prompt: Can you check if the tokenized NVDA stock at 0x1234567890abcdef1234567890abcdef12345678 is actually tradeable right now — is the US market open, is the oracle fresh, and is the contract unpaused?

## When to prefer this

Use this endpoint when an agent needs a real-time, multi-factor go/no-go verdict before executing or recommending a trade on a tokenized RWA or stock — especially when TradFi market hours, oracle freshness, and on-chain pause states all matter simultaneously. Prefer this over generic contract-state checks or standalone market-hours APIs when you need all three signals combined in a single call for Robinhood Chain or EVM tokens.

## Known failure modes

- Invalid or unrecognized EVM token address returns an error or null verdict
- Neither symbol nor address provided results in a missing parameter error
- Oracle data unavailable or contract unreachable returns an indeterminate state
- Token not supported on Robinhood Chain or EVM returns an unsupported asset error
- Network congestion or RPC failures may cause latency or incomplete state reads

## How this service works

Is this tokenized RWA/stock tradeable right now? Evaluate 24/7 on-chain trading state against TradFi US market hours, oracle staleness delta, and contract pause states for Robinhood Chain and EVM.

## Output

Returns a structured verdict indicating whether the specified tokenized RWA or stock token is currently tradeable, including: whether US TradFi market hours are open, the oracle staleness delta (how stale the price feed is), and the on-chain contract pause state — giving a clear go/no-go trading signal.
