## 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 beggar-bot-token-price-94a03097
```

Example prompt: What's the current on-chain USD spot price for WETH and USDC on Base — and flag if either has thin liquidity or a big cross-pool spread?

## When to prefer this

Choose this endpoint when you need trustless, on-chain token prices without relying on centralized price oracles, CoinGecko, or API keys. Ideal for DeFi agents that need real-time Uniswap v3 and Aerodrome prices with liquidity quality signals on Base or Ethereum. Prefer it over off-chain price APIs when you need cross-pool spread awareness and thin-liquidity flags for safe trade execution.

## Known failure modes

- Invalid or non-existent token address returns error or null price
- More than 4 tokens requested in a single call exceeds limit
- Unsupported chain identifier returns validation error
- Token with no Uniswap v3 or Aerodrome pool returns no price data
- Network RPC failure causes timeout or empty response
- Extremely low liquidity token may return price with low confidence flag

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

A JSON response containing the spot USD price for each requested token, the deepest pool identified by quote-side liquidity, cross-pool spread between DEX sources, boolean flags for thin liquidity and price divergence, and an overall confidence score. Pools are derived via CREATE2 — no external indexer or API key required.
