How this service works
Get Arkham DEX swap transactions. Priced per row: $0.40 × limit (default 20, max 1649); pass the smallest useful limit.
Output
Returns a list of swap transactions with full Arkham intelligence enrichment: swap ID, chain, token pair (addresses, symbols, decimals), sender and receiver wallet info including Arkham labels and entity profiles (name, type, social links), USD value at time of swap, block number, block hash, and timestamp. Also returns a total count of matching swaps.
Example use cases
Track large market maker DEX activity
“Show me all the recent on-chain swaps by Wintermute on Ethereum, including the token pairs, trade sizes in USD, and which smart contracts they used.”
Monitor specific token pair swap flow
“Get me the latest USDC/WETH swap transactions on Ethereum from Arkham — I want to see who the senders and receivers are and whether they're labeled entities.”
Investigate whale swap behavior pre-event
“Pull the on-chain swap history for wallet 0x51C72848c68a965f66FA7a88855F9f7784502a7F on Ethereum and show me the Arkham entity attribution and USD values for each trade.”
Technical details
Endpoint
POSThttps://api.arkm.com/x402/swapsWhen to prefer
Use this endpoint when you need on-chain DEX swap data enriched with Arkham's proprietary entity and label intelligence — particularly when identifying which known funds, market makers, or labeled wallets are behind specific swaps. Prefer this over raw blockchain RPC calls or generic DEX APIs when entity attribution is important, or when you need USD-denominated swap values alongside wallet identity context.
Side effects
- Insufficient USDC balance for x402 payment results in 402 Payment Required
- Invalid or unsupported chain identifier returns 400 Bad Request
- Wallet address not found in Arkham database returns empty swaps array
- Rate limiting or quota exceeded returns 429 Too Many Requests
- Malformed POST body or missing required filters returns 400 Bad Request
- Timestamp or block range too broad may return truncated results
