Safe To Send

by Safe to Send in Onchain & crypto

x402 APIPassing, checked 7 h ago

🆕 Before your agent sends, approves or signs to an address: one GO/REVIEW/STOP verdict. Screens OFAC sanctions, Coinbase/Basename identity, wallet vs contract, how long the address has existed, and whether contract logic can be swapped AFTER you send. Every factor returns what it found and what it could not read — a check that did not run never reads as clean, so GO means everything material was actually screened. Not financial advice.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.03.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://402.com.tr/api/x402/safe-to-send?address=0x973a31858f4d2125f48c880542da11a2796f12d6'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://402.com.tr/api/x402/safe-to-send?address=0x973a31858f4d2125f48c880542da11a2796f12d6' \
