## 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 market-intelligence-api-tokenized-stock-premium-history-454ba9a4
```

Example prompt: Show me the premium history for NVDA between Robinhood Chain and Solana xStocks pools over the last 72 hours using 1-hour intervals, and break down the average and median premium by market session.

## When to prefer this

Use this endpoint when you need to study how a tokenized US equity's price diverges across EVM and Solana xStocks venues over time, especially when session-level breakdowns (overnight, weekend, pre-market, regular) matter. Prefer this over generic price feeds when the specific cross-chain premium dynamic is the analytical goal, such as for arbitrage research, pricing model calibration, or cross-venue trading strategy development.

## Known failure modes

- Invalid or unsupported symbol returns an error or empty dataset
- Hours parameter outside 1-720 range may be rejected or clamped
- Invalid interval value (not 15m or 1h) returns a validation error
- Insufficient on-chain liquidity data for the symbol may result in sparse or missing data points
- Payment failure (x402) prevents the response from being returned
- Symbol not tokenized on either Robinhood Chain or Solana xStocks returns no data

## How this service works

Use to study how a tokenized US stock trades away from other venues over time. Returns the premium history of one symbol between Robinhood Chain/EVM pools and Solana xStocks pools (hours=1-720, interval 15m or 1h) with average, median, min and max and statistics per US market session (overnight, weekend, pre-market, regular).

## Output

A time-series of premium values (at 15-minute or 1-hour intervals) showing the price spread between Robinhood Chain/EVM pools and Solana xStocks pools for the requested symbol, plus aggregate statistics (average, median, min, max) computed globally and per US market session (overnight, weekend, pre-market, regular trading hours).
