## 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-tokenized-equity-basis-signal-4d8f7f2a
```

Example prompt: Check the current basis signal for tokenized stocks on Robinhood Chain — I want to know if any are trading at a significant premium or discount to fair value right now, and whether the signal is PREMIUM, DISCOUNT, or FAIR.

## When to prefer this

Use this endpoint when you need a real-time arbitrage signal specifically for tokenized equities trading 24/7 on Uniswap (Robinhood Chain / Base), comparing on-chain price to index-implied fair value. Prefer this over generic crypto signal endpoints when the use case is tokenized stock basis trading rather than native crypto derivatives or sentiment signals.

## Known failure modes

- Invalid or missing x402 PAYMENT-SIGNATURE header returns 402 Payment Required
- No tokenized equity pairs available returns empty result set
- Stale on-chain data may affect fair value comparison accuracy
- Network congestion on Base mainnet may delay payment processing

## How this service works

Premium/discount of a tokenized stock's LIVE Robinhood Chain (Uniswap) price vs its index-implied fair value -- the pure arb signal for 24/7 tokenized equities. Returns on-chain price + venue + 24h volume, fair value, basis_pct, and a PREMIUM/DISCOUNT/FAIR signal. Scam/leveraged pairs filtered.

## Output

Returns the on-chain Uniswap price, trading venue, 24-hour volume, index-implied fair value, basis percentage (basis_pct), and a categorical signal (PREMIUM, DISCOUNT, or FAIR) for filtered tokenized equity pairs, excluding scam and leveraged pairs.
