## 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 tokenized-stock-price-on-chain-fa2811f4
```

Example prompt: What is the current on-chain trading price and liquidity for tokenized AAPL on Base — and how much has it moved in the last 24 hours?

## When to prefer this

Use this endpoint when you need the actual tradeable on-chain price of a tokenized stock on Base — not the NYSE reference price — especially when sizing a trade, checking liquidity depth, or detecting price divergence between TradFi and DeFi. Prefer this over general stock price APIs when the user is operating within the Base ecosystem or trading B20 tokenized equities.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or empty result
- Symbol provided with wrong format (e.g. extra characters) may not match any pool
- Low-liquidity tokens may show stale or unreliable pricing
- On-chain data may lag by one block (~2 seconds on Base)
- Payment failure (insufficient USDC) blocks the call with a 402 response

## How this service works

b20-safety says a tokenized stock is a real issuance; this says what it trades at ON-CHAIN and whether there's liquidity for size. Pass symbol=AAPL (or AAPLc) for the deepest Base pool's price, aggregate liquidity, 24h move and volume; omit symbol for the full directory. Covers every stock Coinbase lists — the roster tops itself up from Coinbase's own API. This is the tradeable Base price, which can diverge from NYSE NAV. Not financial advice.

## Output

Returns a JSON object for a specific ticker containing the Base pool price, aggregate liquidity depth, 24-hour price change percentage, and 24-hour trading volume; or when no symbol is provided, returns a directory of all 82 on-chain tokenized stocks with their key metrics. The price reflects the deepest Base DEX pool and may diverge from NYSE NAV.
