How this service works
Get Arkham portfolio history for an entity. $0.40 per call.
Output
A nested JSON object keyed by blockchain name, then by token ID, containing each token's name, symbol, balance (raw units), current price (USD), and total USD value held by the entity. Multiple chains (e.g. Ethereum, BSC) are returned in a single response.
Example use cases
Hedge fund on-chain holdings audit
“Pull the complete on-chain portfolio for the Arkham entity 'alameda-research' — I need every token they hold across all chains with USD values and balances.”
DeFi protocol treasury monitoring
“What tokens and how much USD does the Aave protocol treasury entity hold right now? Show me the breakdown by chain and token.”
Competitive crypto fund analysis
“Get me the full portfolio breakdown for the entity 'paradigm' on Arkham — I want to see which tokens they're holding, their balances, and the current dollar values across all blockchains.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/portfolio/entityWhen to prefer
Use this endpoint when you need a comprehensive, cross-chain token portfolio for a known Arkham-labeled entity (exchange, fund, protocol, whale) rather than a raw wallet address. Prefer this over raw on-chain lookups when you want entity-level aggregation with USD valuations and token metadata already resolved. Best suited for DeFi research, competitive intelligence, and on-chain fund analysis where Arkham's entity labeling adds context beyond a plain address query.
Side effects
- Unknown or misspelled entity name returns empty or 404 response
- Insufficient USDC balance causes x402 payment failure before data is returned
- Entity with no tracked holdings returns empty portfolio object
- Rate limiting or API key issues result in 401/429 errors
- Stale price data may cause USD values to lag real-time market prices
