## 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 oracle-manipulation-guard-mcp-fd158c37 -d '<json body>'
```

Example prompt: Check this oracle price feed data for signs of manipulation or tampering before I use it in my smart contract: '0x1a2b...price=3200.5,source=chainlink,timestamp=1718000000'.

## When to prefer this

Choose this endpoint when you need to verify oracle data integrity in blockchain or DeFi contexts before acting on price feeds or external data sources, especially when guarding against flash loan attacks, price manipulation, or tampered on-chain data. Prefer this over generic data validation when the specific threat model is oracle manipulation in decentralized systems.

## Known failure modes

- Empty or malformed data string returns a validation error
- Data too large or malformed JSON may result in a 400 bad request
- Ambiguous or non-oracle data may yield inconclusive results
- Service unavailability returns a 5xx error
- Insufficient payment (x402) results in payment required response

## How this service works

The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.

## Output

Returns a structured assessment indicating whether the submitted data contains signs of oracle manipulation, including a threat or risk signal, validation status, and potentially a confidence score or flagged anomalies describing the nature of any detected manipulation.
