## 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 robinhood-chain-tokenized-stock-basis-rh-basis-3262b634 -d '<json body>'
```

Example prompt: What's the current basis — the price gap between the tokenized AAPL on Robinhood Chain and the real Apple stock equity price — and is there an arbitrage opportunity right now?

## When to prefer this

Use this endpoint when you specifically need the price dislocation between a tokenized equity on Robinhood Chain and its real-world counterpart — not for generic crypto token prices, perp funding rates, or DeFi lending. Ideal for arbitrage bots, gap-radar strategies, or pre-trade sanity checks on tokenized stocks. Choose this over generic price feeds when Robinhood Chain onchain-vs-offchain spread is the core signal needed.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty result
- Market closed / after-hours may produce stale or missing reference equity price
- Robinhood Chain oracle outage can cause deviation data to be unavailable
- Payment failure in USDC/stablecoin prevents call from completing
- Network timeout on Railway-hosted service during high load

## How this service works

Three-way basis for a tokenized stock: Lighter perp mark vs canonical onchain spot (Robinhood Chain DEX) vs last real-equity close, with each pairwise spread %. Send { ticker }. The cash-and-carry / basis-trade signal across perp, spot, and the underlying share.

## Output

Returns the real-time basis (price spread or percentage dislocation) between the tokenized version of the requested stock or ETF on Robinhood Chain and the underlying real-world equity price, enabling agents to identify arbitrage gaps, oracle deviations, and timing signals.
