## 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 hyperliquid-backstop-events-analytics-bfda7a31 -d '<json body>'
```

Example prompt: Show me all backstop liquidation events on Hyperliquid for BTC-PERP over the past 30 days, including any insurance fund usage and socialized loss amounts.

## When to prefer this

Choose this endpoint when you need first-party, on-chain-derived data specifically about Hyperliquid backstop liquidation events and insurance fund activity. It is ideal for DeFi risk analysts, trading firms, or agents monitoring platform solvency and socialized loss exposure. Unlike third-party aggregators, this service computes data directly from Hyperliquid's own node fills ledger, making it authoritative for on-chain event reconstruction.

## Known failure modes

- Invalid or missing body payload returns 400 error
- Payment not included or insufficient USDC amount returns 402 Payment Required
- Unsupported filter parameters return 422 validation error
- No backstop events found for the requested filters returns empty result set
- Rate limiting or node sync lag may return stale or delayed data

## How this service works

First-party Hyperliquid trading intelligence: perp fills, position lifecycles, all-wallet leaderboards, trader cohorts, liquidation risk and HIP-4 prediction markets - computed from our own node_fills ledger plus the Hyperliquid public info API (no third-party data source). Free discovery (/healthz, /v1/stats, /.well-known/x402, /v1/openapi.json) and free sample routes (/v1/markets/overview, /v1/assets); all other API calls are $0.001 USDC per request via x402 on Base (no account, no API key).

## Output

Returns a list of backstop liquidation event records from Hyperliquid's node_fills ledger, including event timestamps, affected assets, backstop trigger details, insurance fund consumption, socialized loss amounts, and involved wallet addresses.
