## 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-cross-venue-premium-slippage-intelligence-f63b6927
```

Example prompt: What's the current cross-venue premium for NVDA between Solana's on-chain market and the US exchange — give me the basis point spread, session breakdown, and 24-hour statistics.

## When to prefer this

Choose this endpoint when you need to compare on-chain (Solana) prices against traditional US market prices for tokenized equities or crypto, measure cross-venue basis point spreads, or assess slippage before executing a trade on a tokenized asset. It is particularly useful for arbitrage detection, pre-trade analysis, and understanding session-specific premium behavior (regular hours vs after-hours vs weekends).

## Known failure modes

- Invalid or unsupported symbol returns an error or empty data
- Payment not completed (x402 flow failure) results in 402 Payment Required
- Symbol not listed on Solana tokenized markets returns no on-chain VWAP data
- Rate limit exceeded returns 429
- Stale data if on-chain liquidity is thin for the symbol
