## 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 tokenized-stock-fair-value-c4a5a249
```

Example prompt: What's the current fair value situation for NVDA tokenized stock on Base — is it trading at a premium or discount to the Chainlink reference price, how old is that reference price, and what would be the price impact if I traded $2000?

## When to prefer this

Use this endpoint when you need a consolidated, single-call assessment of a tokenized stock's fair value on Base — especially before executing a DEX trade. It uniquely combines Chainlink reference price staleness, DEX premium/discount in bps, and pool liquidity into one response, which no generic price feed or DEX API provides together. Prefer it over raw Chainlink queries when you need to understand the full risk picture including session status, dividends, and trading pauses.

## Known failure modes

- Unknown or unsupported stock symbol returns an error or empty result
- Token address not recognized if not listed by Coinbase
- amountUsd malformed (non-numeric string) may return a parsing error
- Reference price age may be very high when US market is closed, indicating frozen feed
- Pool depth data unavailable for illiquid or newly listed tokens

## How this service works

Tokenized stocks trade 24/7 on Base; their reference price (Chainlink, used by Aave and Morpho) freezes when the US market shuts. One call: the US session, the reference and its age, the DEX premium/discount in bps against it, pool depth and rough impact for amountUsd, paused features and any announced dividend. Covers every stock Coinbase lists. Not financial advice.

## Output

A structured response containing: whether the US equity session is open, the Chainlink reference price and its age in seconds/minutes, the DEX spot price and its premium or discount versus the reference price in basis points, pool liquidity depth, estimated price impact for the requested USD trade size, any features currently paused (e.g. minting/redemption), and any announced dividends for the stock.
