Ai Tx Explain

by AI Transaction Explainer in Onchain & crypto

x402 APIPassing, checked 1 h ago

Give a Base transaction hash and AI explains what it actually did in plain English — the action, a risk read (failed tx, risky approval, high-value transfer), and notes. Turns raw calldata into an answer agents and humans can use.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.04.

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/ai-tx-explain?hash=0x68fdf10f8eb842afcddf79b2a779ed78e5be35d698e95cee1966f1787eb02b5e'

# 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/ai-tx-explain?hash=0x68fdf10f8eb842afcddf79b2a779ed78e5be35d698e95cee1966f1787eb02b5e' \
