## 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 arbitrum-one-token-price-feed-x402-donnyautomation-com-03c85fed
```

Example prompt: What's the live price of ARB in USD right now on Arbitrum One — and how confident is the quote based on pool liquidity?

## When to prefer this

Choose this endpoint when you need a real-time, on-chain spot price for any ERC-20 token on Arbitrum One (not just a fixed curated list) and need a confidence signal to avoid acting on thin-pool prices. It is preferable over off-chain price APIs when you specifically need Arbitrum L2 DEX-derived prices with liquidity transparency for trading bots, price oracles, or risk checks.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error or null price
- Token with no active Arbitrum One pools returns no price data
- Very thin liquidity pool returns a low confidence rating, flagging the price as unreliable
- Network or RPC issues with Arbitrum One may cause request failure
- Incorrect symbol casing or typos result in no match

## How this service works

Spot token price in USD on Arbitrum One, read from SushiSwap and Uniswap v3 fee tiers pools at call time. Returns priceUsd, the routed pair, backing liquidityUsd, confidence and blockNumber. Requires ?symbol=TICKER (e.g. ARB) or ?token=0xADDRESS. Errors: 400 missing_symbol|unknown_token, 404 no_reliable_price when pools are too thin, 502 upstream_read_failed. Depth is /liquidity; a size-aware quote is /slippage. Chain-pinned; bare /price = BSC.

## Output

Returns a JSON object containing: priceUsd (the current spot price in USD), the DEX pair used to derive the quote (e.g. WETH/USDC on Uniswap v3), the USD liquidity backing the quote, and a confidence rating indicating whether the pool is deep enough to trust the price as a market price.
