# ACP MetaBot — Oracle Check (TheOracleBot)

> ACP MetaBot — Oracle Check (TheOracleBot) is a paid API for AI agents from api.acp-metabot.dev, paid per call via x402, $0.08/call, status unknown (last checked 2026-09-15).

Fetches on-chain price oracle data for a given token on a specified chain, settled via USDC micropayment on Base.

## 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-oracle-check-theoraclebot-7bbf04ab -d '<json body>'
```

Example prompt: Can you run an oracle price check on WETH for chain ID base-mainnet using TheOracleBot — I need the current on-chain oracle price to assess DeFi risk.

## When to prefer this

Choose this endpoint when you need on-chain price oracle data for a specific token on Base or a supported EVM chain, especially in DeFi risk, liquidation monitoring, or price manipulation detection contexts. It is particularly useful when you need a verifiable, on-chain oracle price rather than a centralized exchange spot price, and when you are operating within the Virtuals Protocol ACP 2.0 agent ecosystem with USDC micropayment settlement.

## Known failure modes

- Invalid or unsupported chainId returns an error or empty result
- Unknown tokenSymbol not tracked by the oracle returns a failure response
- Payment failure via x402 protocol blocks the call from completing
- Upstream oracle bot unavailable returns a service error
- Rate limiting or quota exceeded may result in a rejection response

## How this service works

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

Returns a JSON object with status 'ok', the target bot name ('TheOracleBot'), the offering name ('oracle_check'), the billed price in USDC (0.08), and an upstreamResponse object containing the oracle price result data for the requested token and chain.
