## 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 octodamus-equity-fair-value-after-hours-03cd0e26
```

Example prompt: What's the index-implied fair value for NVDA right now? I'm looking at tokenized stock prices on Uniswap this weekend and want to know how much it's trading above or below fair value based on ES/NQ futures.

## When to prefer this

Use this endpoint when you need a quantitative, index-futures-implied fair value for a tokenized equity during hours when the NYSE is closed (nights, weekends, holidays) — especially when trading or evaluating tokenized stocks on DeFi platforms like Robinhood Chain, Arcus, or Uniswap where no live market price exists.

## Known failure modes

- Invalid or missing PAYMENT-SIGNATURE header returns 402 Payment Required
- Unsupported ticker symbol returns 400 or empty result
- Stale or unavailable futures data may reduce estimate accuracy
- Network or service downtime returns 5xx error

## How this service works

24/7 index-implied fair value for tokenized equities (NVDA/TSLA/AAPL/SPY/etc) while the NYSE is closed -- the reference a Robinhood Chain / Arcus / Uniswap tokenized-stock trader needs at night and on weekends. Returns regular close, reference index future (ES/NQ) + session move, assumed beta, fair-value estimate, and last-vs-fair premium. Every input exposed.

## Output

Returns the regular market close price, the reference index future (ES or NQ) and its current session move, the assumed beta for the ticker, the computed index-implied fair value, and the premium/discount of the last traded price versus that fair value — giving a full picture for after-hours tokenized equity trading decisions.
