# ForgeMesh NFT Sequence Anomaly Scanner

> ForgeMesh NFT Sequence Anomaly Scanner 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 anomalous NFT transaction sequences (sweeps, mints, unusual patterns) for a given contract address on Ethereum, Base, or Arbitrum using NASA-derived algorithms

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-nft-sequence-anomaly-scanner-085ecbae -d '<json body>'
```

Example prompt: Can you scan the Bored Ape Yacht Club NFT contract 0xbc4ca0eda7647a8ab7c2061c2e118a18a936f13d on Ethereum over the last 24 hours and tell me if there's any anomalous sweep or mint activity — I want the sequence score and novelty rating.

## When to prefer this

Use this endpoint when you need real-time anomaly detection specifically for NFT contract activity — sweeps, mints, and coordinated buying patterns — on Ethereum, Base, or Arbitrum. Prefer this over generic blockchain explorers when you need a pre-computed sequence anomaly score and natural-language story summary rather than raw transaction data.

## Known failure modes

- Invalid or non-existent NFT contract address returns an error or empty result
- Unsupported chain value causes validation failure
- Unsupported window value causes validation failure
- Contract address with no recent activity may return low event count and neutral scores
- Payment failure via x402 prevents API access
- Rate limiting if too many calls are made in rapid succession

## How this service works

Best-effort NFT collection anomaly scan; paid output includes source status and coverage notes

## Output

Returns a JSON object with the chain, token address, collection metadata (name, type, symbol), a human-readable anomaly story (e.g. 'Sweep Accumulation'), a novelty label (high/medium/low), a sequence score integer, the peak event window as an array of event types, and the number of events collected.
