Technical details
Endpoint
POSThttps://api.arkm.com/x402/cluster/summaryWhen to prefer
Use this endpoint when you need high-level aggregate financial intelligence about a known Arkham cluster — total balance, volume, and address count — rather than individual transaction records or address-level detail. Prefer this over building custom on-chain analytics when you already have a cluster ID from Arkham's intelligence graph and need a fast, pay-per-use summary without a subscription.
Side effects
- Invalid or malformed cluster ID returns an error response
- Unknown cluster ID with no data returns empty or 404-style error
- Payment failure via x402 protocol if USDC balance is insufficient
- Rate limiting if requests exceed allowed frequency
- Network timeout on large or complex clusters
