## 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 base-defi-liquidation-telemetry-8631d6f5
```

Example prompt: Pull the liquidation telemetry for Base lending protocols over the last 6 hours — I want the total debt repaid, collateral seized, estimated liquidation bonuses, and a breakdown by asset, focusing on aave-v3.

## When to prefer this

Use this endpoint when you need decoded, aggregated liquidation event data specifically from the Base blockchain's lending protocols (especially Aave v3), including USD-denominated summaries and per-asset breakdowns — without having to decode raw event logs yourself. Prefer it over generic blockchain explorers when you need ready-to-use telemetry rather than raw transaction data.

## Known failure modes

- Invalid window parameter (e.g. beyond ~12h max) returns an error or empty result
- Unknown protocol enum value returns a validation error
- No liquidation events in the requested window returns zero counts
- Rate limiting or payment failure (x402) if USDC payment is not provided
- Temporary unavailability of Base event log data source causes partial or empty response

## How this service works

On-chain DeFi liquidation telemetry for Base lending protocols: recent LiquidationCall events decoded by us from public Base event logs — count, total debt repaid and collateral seized (USD), estimated liquidation bonus, per-protocol and per-asset breakdown, and the recent events (user, liquidator, collateral, debt).

## Output

A structured JSON response containing: total count of LiquidationCall events, total debt repaid and collateral seized in USD, estimated liquidation bonus, breakdown by protocol and by asset, and a list of recent individual liquidation events with fields for user, liquidator, collateral asset, and debt asset.
