Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Give me an AI-generated summary of all the major DeFi hacks and exploits that happened in 2024, including total losses and notable incidents.

## When to prefer this

Choose this endpoint when you need a natural-language AI summary of DeFi security incidents for a specific year, rather than raw data or individual hack records. Ideal for generating reports, briefings, or trend analysis without needing to aggregate multiple data sources manually. Best when paying per-use is acceptable and no persistent API key management is desired.

## Known failure modes

- Invalid or future year returns empty or error response
- Payment failure via x402 protocol results in 402 Payment Required with payment details
- Year with no recorded hacks may return empty summary
- Network or upstream data unavailability may cause 5xx errors
- Malformed request body returns 400 Bad Request

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

An AI-generated narrative summary of DeFi hacks and exploits for the specified year, including notable incidents, affected protocols, estimated total losses, and key security trends observed during that period.
