## 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 speer-cyber-defense-base-blockchain-contract-intelligence-8b5f4871
```

Example prompt: Can you pull the blockchain intelligence report on this Base network contract address 0x1234abcd... and tell me if it looks safe or suspicious?

## When to prefer this

Choose this endpoint when you need on-chain intelligence specifically for a Base network smart contract address, particularly for security vetting, scam detection, or DeFi due diligence. It is pay-per-call at $0.01 USDC via x402, making it cost-effective for agent workflows. Prefer it over generic blockchain explorers when you need a security-focused summary rather than raw transaction data.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not found on Base blockchain may yield empty or error response
- HTTP 503 returned for failed analysis (not billed)
- Non-Base chain addresses (e.g. Ethereum mainnet, Solana) may not be supported
- Network timeouts or on-chain data unavailability

## How this service works

Cybersecurity micropayments API for AI agents — pay-per-call USDC on Base and Solana (x402 v2). Free utility services under /v1/free/* and gateway select under /v1/gateway/* (Public). Paid cybersecurity analysis, CVE/security news feeds, Base blockchain intelligence, network intel utilities, composite domain/URL reports, research, conversion, verification, and feeds. Failed security analyses are not billed (HTTP 503).

## Output

A JSON response containing an analysis summary of the given Base blockchain contract address, including status indicator, tool used, and a textual summary of the contract's on-chain profile and any security-relevant findings. Failed analyses return HTTP 503 and are not billed.
