## 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-smart-contract-intelligence-6bdc3758
```

Example prompt: Can you pull the blockchain security intelligence report on the Base smart contract at address 0x4d5a3C59f7A8E1B2c3D4e5F6a7B8c9D0e1F2a3B4 — I want to know if it's safe before my team interacts with it?

## When to prefer this

Choose this endpoint when you need on-demand, pay-per-call security intelligence on a specific Base blockchain smart contract address without committing to a subscription. It is ideal for AI agents performing automated due diligence, incident response, or risk assessments on-chain, especially when the cost per query needs to stay minimal ($0.01 USDC). Prefer this over generic blockchain explorers when you need cybersecurity-specific analysis rather than raw transaction data.

## Known failure modes

- Contract address not found or invalid format — returns error response
- Base network data temporarily unavailable — returns HTTP 503, no charge
- Malformed address parameter — may return validation error
- Rate limiting or payment failure — request not processed

## 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

Returns a JSON object with an ok status flag, tool identifier, a status field, and a summary string describing the contract intelligence findings. In failure or unavailable scenarios, a 503 is returned and no billing occurs.
