## 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-f3c2d1f7 -d '<json body>'
```

Example prompt: Pull the recent backstop liquidation events from Hyperliquid — I want to see which positions were liquidated by the backstop fund in the last 24 hours, ideally filtered to BTC-PERP.

## When to prefer this

Choose this endpoint when you need first-party, operator-neutral backstop liquidation event data computed directly from Hyperliquid node fills — particularly when you need reliable liquidation history without relying on any third-party data aggregator. Ideal for risk monitoring, post-liquidation forensics, or studying insurance fund behavior on Hyperliquid perps.

## Known failure modes

- Invalid or missing required body parameters returns 400 Bad Request
- No backstop events found for the given filters returns empty result set
- Rate limit exceeded on free quota returns 429 Too Many Requests
- Payment required when free quota exhausted returns HTTP 402 with x402 pay-per-call prompt
- Upstream Hyperliquid node data temporarily unavailable returns 503 Service Unavailable
- Malformed JSON body returns 400 with parse error

## How this service works

Operator-neutral Hyperliquid trading intelligence — perp fills, position lifecycles, all-wallet leaderboards, trader cohorts, liquidation risk and prediction markets. Every endpoint is FIRST-PARTY: computed from our own node_fills ledger and the Hyperliquid public info API (no third-party data source). Free quota, then HTTP 402 (x402: pay-per-call in USDC, no account, no key).

## Output

Returns a list of backstop liquidation events on Hyperliquid, each containing details such as event timestamp, affected wallet address, asset/coin, liquidated position size, liquidation price, and backstop fund involvement metrics — all computed from first-party node fill data.
