## 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-dff041d1
```

Example prompt: What's the premium history for NVDA between the Robinhood Chain EVM pools and Solana xStocks over the last 72 hours at 1-hour intervals, and break down the average and median by market session?

## When to prefer this

Use this endpoint when you need to study or monitor how a specific tokenized US stock's price diverges between Robinhood Chain/EVM liquidity pools and Solana xStocks pools over time, especially for identifying arbitrage patterns, session-specific premiums, or historical spread statistics. Prefer this over generic price feeds when cross-venue blockchain premium analysis with session-level breakdown is the goal.

## Known failure modes

- 404 if the symbol is not covered or not traded on both EVM and Solana pools (not charged)
- 400 if hours is outside 1–720 or interval is not '15m' or '1h'
- Payment required / x402 error if USDC payment is not attached
- Empty or sparse data if the symbol has low liquidity on one of the venues
- Timeout if the look-back window is very long (720h) with 15m interval

## How this service works

Tokenized stock premium history: premium 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). Use to study how a tokenized stock trades away from other venues.

## Output

A time-series of premium/discount values between Robinhood Chain/EVM pools and Solana xStocks pools for the requested symbol and period, aggregated at the chosen interval (15m or 1h), plus summary statistics (average, median, min, max) broken down by US market session (overnight, weekend, pre-market, regular).
