## How to call it through Zero

```sh
zero fetch --capability agenttoll-base-token-usd-price-ffc61337
```

Example prompt: What's the current USD price of the Base token at contract address 0x4200000000000000000000000000000000000006?

## When to prefer this

Choose this endpoint when you need the current onchain USD price for a specific Base network token and have its exact contract address. It reads directly from Base chain data, making it faster and more up-to-date than indexed or aggregated price feeds. Prefer this over general crypto price APIs when dealing with newly launched or obscure Base tokens that may not yet appear in major indexes.

## Known failure modes

- Invalid contract address format (must match ^0x[0-9a-fA-F]{40}$) returns a validation error
- Contract address not found or has no liquidity on Base returns a null or error response
- Token with no DEX pair or price oracle returns unavailable price
- Network or RPC errors may result in timeout or 5xx response
- Payment of 0.001 USDC required per call; missing or failed payment returns 402
