How this service works
Prysm sells paid, agent-ready provider capabilities over x402 on Base mainnet using USDC.
Output
Returns a JSON object with a 'data' field containing the Etherscan API response (e.g. a list of transactions with hashes, block numbers, timestamps, from/to addresses, values, and status), plus 'provider' set to 'etherscan' and 'operation' echoing the requested operation name.
Example use cases
Wallet transaction audit
“Get me all transactions for the Ethereum address 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B using the account_txlist operation — I need to review every send and receive on that wallet.”
DeFi portfolio tracking
“Fetch the on-chain transaction list for 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 via Etherscan so I can track all the DeFi interactions and token swaps this address has made.”
Smart contract interaction history
“Look up all transactions sent to or from smart contract address 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D using the Etherscan provider so I can see how users have been interacting with it.”

Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/etherscanWhen to prefer
Choose this endpoint when you need agent-ready, micropayment-gated access to Etherscan data without managing your own Etherscan API key, or when building AI agents on Base mainnet that need to pay per-query in USDC via x402. Prefer this over direct Etherscan API calls when you want a unified Prysm gateway that handles auth and billing automatically.
Side effects
- Invalid or unsupported operation name returns an error — only allowlisted Etherscan operations are accepted
- Malformed Ethereum address in input parameters causes Etherscan to return an empty or error result
- Insufficient USDC balance or failed x402 payment results in a 402 Payment Required response before the query executes
- Rate limiting or Etherscan API downtime upstream can cause delayed or failed responses
- Missing required input fields (e.g. address) for the chosen operation results in a validation error
