# Market Intelligence API – Tokenized Stock Cross-Chain Premium

> Market Intelligence API – Tokenized Stock Cross-Chain Premium is a paid API for AI agents from api.marketintelligenceapi.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Returns volume-weighted price premium (in basis points) between tokenized US stock pools on Robinhood Chain/EVM DEX and Solana xStocks, per 15-minute bin, with both prices, volumes, and market session context.

## 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-cross-chain-premium-a7b5c2ce
```

Example prompt: What's the current cross-chain premium for NVDA and TSLA between Solana xStocks and Robinhood Chain right now — give me the basis points spread, both VWAPs, and which market session we're in?

## When to prefer this

Use this endpoint when you need to identify price discrepancies between tokenized US equities on Solana xStocks pools versus Robinhood Chain or EVM DEX pools, expressed as volume-weighted basis point premiums in 15-minute bins. Prefer this over generic OHLCV or signal endpoints when the specific use case is cross-chain arbitrage detection or monitoring tokenized stock price alignment across chains.

## Known failure modes

- Invalid or unsupported symbol returns empty premiums array
- No trading data available for the requested symbol or time window
- Rate limiting or payment failure returns 402 or 429 error
- Solana or EVM pool data temporarily unavailable causing incomplete premium calculation
- Malformed symbols filter parameter returns 400 bad request

## How this service works

Tokenized stock price premium and arbitrage gaps: latest premium in basis points of the same stock token (NVDA, TSLA, SPY, ...) between the main on-chain pools (Robinhood Chain and EVM DEX) and Solana xStocks pools, volume-weighted per 15-minute bin, with both prices, volumes and the US market session. Filter with symbols=. Use to find price gaps.

## Output

Returns a JSON object with a list of premium records per symbol per 15-minute bin, each containing the time, symbol, main chain VWAP, Solana VWAP, premium in basis points, premium percent, 1-hour volumes in USD for each chain, and the US market session (e.g. AFTER_HOURS, REGULAR). Also includes aggregate fields: number of symbols compared and average absolute premium in basis points.
