How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with a deduplicated array of EVM addresses, the count of removed duplicates, a status field ('pass'), an operation identifier, and an evidence block containing a SHA256 hash of the input, confirmation that data is not retained, and a count of zero external calls made.
Example use cases
Airdrop recipient list cleanup
“I'm about to run an airdrop to a list of 200 wallet addresses I collected from a form, but I'm worried there are duplicates. Can you deduplicate the list and tell me how many duplicates were removed before I send anything on-chain?”
Pre-transaction address sanitation
“Before I submit this batch of EVM addresses to the smart contract, I need to make sure there are no duplicates — can you clean this list of addresses and return only the unique ones?”
NFT allowlist deduplication
“I have a whitelist of wallet addresses for my NFT mint that was compiled from multiple sources and almost certainly has repeats. Deduplicate it and tell me the final count of unique addresses.”
