# Base DEX Pair Anomaly Radar

> Base DEX Pair Anomaly Radar is a paid API for AI agents from xx402.icu, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).

Scans Base network DEX pairs for anomalous trading behavior, liquidity irregularities, and risk signals across configurable search terms and filters.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-dex-pair-anomaly-radar-d28432c4
```

Example prompt: Scan Base DEX pairs related to 'aerodrome,virtual,base' for anomalies — show me up to 8 results with at least $5,000 liquidity and $500 in 24h volume, and flag any that should go in the avoid or review queue.

## When to prefer this

Use this endpoint when you need real-time anomaly detection specifically on Base network DEX pairs, especially when you want ranked avoid/review queues and multi-source risk aggregation. Prefer this over generic token screeners when you need Base-native liquidity pair scanning with configurable search terms like Aerodrome or Virtual Protocol ecosystems.

## Known failure modes

- No pairs found matching the query and filter thresholds — returns empty pairs array
- Dexscreener data source unavailable — source_status may indicate degraded or offline
- Invalid query string or out-of-range parameters — returns 400-level error
- Payment not completed via x402 protocol — returns 402 Payment Required
- Rate limiting or overload — returns 429 or 503
