## How to call it through Zero

```sh
zero fetch --capability booaip-token-quote-3858fc0c
```

Example prompt: What's the current USD price for the MKR token at contract address 0x9f8f72aa9304c8b593d555f12ef6589cc3a579a2?

## When to prefer this

Choose this endpoint when you need a quick USD price lookup for a specific ERC-20 token identified by its contract address, especially for DeFi or AI agent workflows requiring pay-per-call pricing via x402/USDC on Base. Prefer this over broader market APIs when you already have the contract address and need a lightweight, low-cost, programmatic price feed without API key management.

## Known failure modes

- Token contract address not found or not indexed — returns found: false
- Invalid contract address format — may return error or found: false
- Token exists on-chain but has no reliable price feed — found: false
- Network or upstream data provider outage — HTTP 500 or timeout
- Payment failure via x402 — HTTP 402 if USDC payment not processed
