## How to call it through Zero

```sh
zero fetch --capability agentdiet-contract-scanner-91e5b82e
```

Example prompt: Can you scan the smart contract at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and tell me what you find out about it?

## When to prefer this

Choose this endpoint when you need to programmatically scan and extract structured intelligence about a blockchain smart contract address, especially within an agent workflow that supports x402 micropayment settlement in USDC on Base. It is well-suited for automated due diligence, contract auditing pipelines, or any agent that needs on-chain contract data at $0.01 per call.

## Known failure modes

- Invalid or missing contract address returns empty or error data
- Non-existent contract address may return no results
- Payment failure via x402/USDC on Base blocks the request
- Unsupported chain or address format may cause lookup failure
- Rate limiting or gateway errors may return non-200 responses

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

Returns a JSON object with a 'data' field containing contract intelligence, a 'status' field (e.g. 'ok'), and a 'roi_proof' object including a compression_ratio_pct metric indicating data efficiency of the scan result.
