## 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 stockkit-quote-tokenized-stock-swap-price-on-robinhood-chain-ed3ad63f
```

Example prompt: What's the current buy quote on StockKit for $200 worth of NVDA tokenized stock — how many tokens would I get and what's the effective price per token?

## When to prefer this

Choose this endpoint when you need a real-time, on-chain execution quote for a tokenized equity on Robinhood Chain before submitting a swap — especially when you need Uniswap v3 pool-accurate pricing, fee tier data, and gas estimates. Prefer this over traditional brokerage price feeds when you are building DeFi-adjacent workflows that settle on-chain in USDG.

## Known failure modes

- Invalid or unsupported ticker symbol returns an error (symbol not listed on Robinhood Chain)
- Amount of zero or non-numeric amount string returns validation error
- Missing required query parameters (symbol, side, amount) returns 400
- Pool liquidity too low for requested trade size may return null effectivePricePerToken
- Payment not included or invalid x402 payment header returns 402 Payment Required
- Network congestion on Robinhood Chain may delay or fail gas estimation
