Contract Audit

by ManyLives Onchain in Onchain & crypto

x402 APIPassing, checked 2 h ago

Security pre-check for any Base network contract before your agent interacts with it (vault, router, token, bridge): built-in powers in its code (mint, pause, blacklist, upgrade, withdraw, self-destruct, delegatecall), proxy and who controls it (a single wallet or a multisig contract), whether the source is publicly verified, with red flags, a risk level and a plain-language verdict. Facts, 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 $0.02.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.manylives.me/paid/contract/audit?address=0x4200000000000000000000000000000000000006'

# 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://api.manylives.me/paid/contract/audit?address=0x4200000000000000000000000000000000000006' \
  | grep -i '^payment-required:' | cut -d' ' -f2 | tr -d '\r' | base64 --decode
JavaScript: pay and call

// Not sure it's safe to pay? ToolVet checks it first for $0.005. Pay for that from a separate
