## 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-spread-dislocation-intelligence-65837009 -d '<json body>'
```

Example prompt: Check the spread and price dislocation for tokenized AAPL on Robinhood Chain for a $500 clip, assuming a 0.3% pool fee — I want to know if there's a gap versus the real equity right now.

## When to prefer this

Use this endpoint when you specifically need spread and dislocation analysis between a tokenized equity on Robinhood Chain and the underlying real-world stock or ETF. It is the right choice for arbitrage detection, pre-trade cost estimation, and monitoring price gaps in tokenized stock markets. Prefer this over generic DEX spread tools when the asset is a Robinhood Chain tokenized equity rather than a native crypto token.

## Known failure modes

- Unknown or unsupported ticker returns an error or empty result
- Ticker for a stock not listed on Robinhood Chain tokenized market may return no data
- Invalid feePct value (e.g. negative or extreme) may produce unreliable spread estimates
- Stale oracle data may cause dislocation metrics to lag real market conditions
- Network or upstream data feed outage may return 5xx errors

## How this service works

Effective round-trip execution cost for a tokenized stock right now: best executable buy vs best executable sell price for a small reference clip across all venues, and the resulting effective spread %, modeled with pool fee + constant-product impact. Send { ticker, clipUsd?, feePct? }. The cost-to-trade snapshot for execution agents.

## Output

Returns computed spread metrics and dislocation data for the specified tokenized stock ticker on Robinhood Chain, including the gap between the on-chain token price and the reference equity price, estimated execution cost for the given clip size, and pool-fee-adjusted spread figures. Useful for detecting arbitrage opportunities or estimating pre-trade costs.
