Crypto Wallet Profiler: Age, First Funder, Counterparties and Holdings

Give it a list of wallet addresses and get back one profile per wallet: how old it is, who funded it, who it deals with most, its recent and large transfers in USD, and its balance. Works on Base, Ethereum, Arbitrum, Optimism and Polygon, plus Solana (holdings valued in USD and recent activity).

• Know who you're dealing with. First activity and age in days, the address that first funded the wallet, and whether it's a plain wallet, a contract (token, NFT, proxy) or a wallet with an EIP-7702 delegation.
• Who it trades with. The ten addresses it transferred with most often, with a sent/received split and the last time they interacted.
• Big moves. Transfers of $1,000 or more in the native coin, the wrapped native coin, USDC or USDT, largest first, plus the 20 newest transfers of any kind (native, ERC-20, NFTs).
• Solana portfolios. SOL and every SPL / Token-2022 balance valued with Jupiter prices, dust and unpriced spam summed separately, and how active the address has been.
• No API keys to manage. One item per address, the same data as the agent-data-api wallet routes.

Who uses this

• Compliance and risk teams: a quick first look at a counterparty before paying or onboarding it: how old, who funded it, who it deals with.
• Crypto researchers and analysts: profile airdrop farmers, whales or a project's team wallets in bulk.
• Sales and BD in web3: see what a prospect's treasury holds and how active it is.
• AI agents: a structured wallet summary to reason over, without running an indexer.

Addresses that aren't valid for the chain, or whose lookup fails, get an item with an error field and aren't charged.

What it covers, and what it doesn't

• EVM: activity, counterparties and large transfers cover the newest 100 transfers in each direction (moreHistory: true means there are older ones). Internal (contract-made) native transfers are included on Ethereum and Polygon only. Large transfers are priced at today's price, in the native coin, wrapped native coin, USDC and USDT.
• Solana: tokens worth at least $1 are listed (up to 25); smaller balances are summed as dust. Activity comes from the newest 1,000 transaction signatures.
• It reports facts, not labels: it doesn't say whether a wallet is an exchange, a scammer or sanctioned.

Pricing

Pay per event: charged per wallet profile returned. Invalid addresses and failed lookups cost nothing.
