Agent Intel Sybil Airdrop Farmer Check

by SiteCheck Agent Intel & Dev in Onchain & crypto

x402 APIFailing, checked 8 h ago

Checks 2 to 10 Ethereum wallets for shared counterparties: addresses that several of them sent to or received from in their most recent 50 transactions (Blockscout). Reports the shared addresses and a POSSIBLE_CLUSTER signal. Recent-page only, no funding-source trace, so it finds some clusters and misses others.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.fadeandco.workers.dev/api/agent-intel/sybil-airdrop-farmer-check?wallets=0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045%2C0xfbfEaF0DA0F2fdE5c66dF570133aE35f3eB58c9A'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
