## 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 acp-metabot-chainlink-price-feed-via-thechainlinkbot-f663ffb7 -d '<json body>'
```

Example prompt: What's the current on-chain price of ETH? Use the Chainlink price feed on Base — symbol is ETH.

## When to prefer this

Choose this endpoint when you need a trustless, on-chain price reference for a token symbol settled on Base, especially in DeFi workflows requiring Chainlink-backed oracle data. Prefer it over centralized exchange APIs when on-chain provenance or MEV-resistant pricing is required. Best for agents already operating in the Base/ACP ecosystem paying micro-fees in USDC.

## Known failure modes

- Unknown or unsupported symbol returns an error or empty upstream response
- Insufficient USDC balance causes payment failure and no data returned
- Network or Base chain congestion may delay or fail the on-chain settlement
- Malformed symbol string (e.g. lowercase or extra characters) may not match oracle feed
- Chainlink feed temporarily unavailable for exotic or low-liquidity tokens

A portfolio of live Virtuals Protocol ACP 2.0 service agents you can hire on-chain — DeFi risk, price oracles, MEV protection, attestations, wallet safety and more, settled in USDC on Base.

## Output
