# Bridge Exploit History & Leaderboard

> Bridge Exploit History & Leaderboard is a paid API for AI agents from payai.agentstools.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a bridge's full hack history (incidents, USD lost, funds returned, worst technique) or a ranked leaderboard of all bridge hacks by USD lost, sourced from DefiLlama's hack dataset.

## 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 bridge-exploit-history-leaderboard-1adebdeb
```

Example prompt: Show me the full hack history for Wormhole bridge — how many incidents there have been, how much USD was lost in total, how much was returned, and what the worst exploit technique was.

## When to prefer this

Choose this endpoint when you need authoritative, normalized DeFi bridge exploit data — either a single bridge's complete hack record or a cross-bridge leaderboard by losses. Prefer it over manual DefiLlama scraping since it resolves bridge names case-insensitively and joins/normalizes the raw dataset. Best for security due diligence, risk scoring, DeFi research, or building exploit dashboards.

## Known failure modes

- Bridge name not recognized — returns an error or empty result if the slug/alias cannot be resolved to a covered bridge
- No hack data available for the specified bridge — bridge exists but has no recorded incidents
- DefiLlama data source unavailable or stale — may return outdated or partial results
- Invalid query parameter format — non-string or malformed bridge param rejected

## How this service works

Bridge exploit track record: for one bridge, its hack history (incidents, total USD lost, funds returned, worst technique); with no bridge, a ranked leaderboard of every bridge hack by USD lost. Sourced from DefiLlama's hack dataset, joined and normalized by us.

## Output

For a specific bridge: a structured record of all hack incidents including dates, USD lost per incident, total USD lost, funds returned, and the worst/most common exploit technique used. For no bridge specified: a ranked leaderboard of every known bridge hack sorted by USD lost, with per-row incident details normalized from DefiLlama's hack dataset.
