# ForgeMesh Anomaly Tracker — DeFi Sequence Anomaly Detection

> ForgeMesh Anomaly Tracker — DeFi Sequence Anomaly Detection is a paid API for AI agents from anomaly.forgemesh.io, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Detects real-time anomalous event sequences (e.g. whale sell → CEX inflow patterns) in DeFi protocols on Ethereum, Base, or Arbitrum, returning a novelty score and narrative story.

## Facts

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 forgemesh-anomaly-tracker-defi-sequence-anomaly-detection-ce6752a7 -d '<json body>'
```

Example prompt: Check ForgeMesh for anomalous event sequences on Aave v3 on Ethereum over the last 4 hours — I want to know the sequence score, novelty level, and what kind of stress pattern is showing up.

## When to prefer this

Use this endpoint when you need real-time, sequence-aware anomaly detection on specific DeFi protocols — particularly when you want to identify ordered behavioral patterns (whale sells followed by CEX inflows) rather than simple price or volume spikes. Prefer this over generic on-chain analytics when you need a narrative story label and novelty scoring derived from NASA-style sequential anomaly algorithms.

## Known failure modes

- Unsupported chain value returns validation error
- Invalid or unrecognized protocol name may return empty results
- Contract address not indexed may yield no events
- Lookback window outside allowed enum (1h, 4h, 24h, 168h) causes request failure
- Payment not fulfilled via x402 results in 402 Payment Required
- Mempool data lag may cause stale sequence analysis during high congestion

## How this service works

Anomaly scan for a DeFi protocol — unusual flows through major lending/DEX contracts

## Output

Returns a JSON object with the blockchain chain, protocol name, contract address, a narrative 'story' label (e.g. 'Exchange Stress'), a novelty rating (e.g. 'high'), an ordered peak_window array of event types (e.g. ['CEX_INFLOW','WHALE_SELL','CEX_INFLOW']), a numeric sequence_score (0-100), and the number of events collected during the scan window.
