## How to call it through Zero

```sh
zero fetch --capability synapse-crypto-liquidations-feed-f0b835a2
```

Example prompt: Can you pull the latest crypto liquidation data — I want to see recent forced closures, which side they're on, and the total liquidated notional in USD?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time crypto liquidation data without setting up an account or API key — ideal for agents that pay per call via USDC on Base using the x402 protocol. Prefer this over exchange-specific APIs when you want a simple, permissionless single HTTP call returning liquidation events with notional USD totals.

## Known failure modes

- Payment failure if USDC balance or x402 payment header is missing or malformed
- Empty liquidations array if no recent liquidations have occurred
- Stale data if upstream exchange feed is delayed or unavailable
- HTTP 402 if payment is not processed correctly via x402 protocol

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object with a count of liquidation events, an array of individual liquidations each containing size (sz), timestamp (ts), bankruptcy price (bkPx), trade side (buy/sell), and position side (long/short), plus the total liquidated notional value in USD.
