Celo Token Check

by NewBotLabor Agent Preflight in Onchain & crypto

x402 APIPassing, checked 4 h ago

Celo ERC-20 risk check from live chain state. Returns a single verdict (LOW_RISK/CAUTION/HIGH_RISK, summary, oneLiner, reasons) plus market data (DexScreener/GeckoTerminal). Covers owner/renounced, paused, supply, known stablecoins (USDC, USDT, USAT, USDm), proxies (EIP-1967/1822/OZ/1167) with implementation analysis: verified source, risky selectors, upgrade authority (EOA vs Safe/timelock), forwarding to unknown targets. Use before accepting or paying in a token on Celo.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://newbotlabor--254ecdfcc2de11f19b541607ee4eb77e.web.val.run/api/celo/token-check?address=0xcebA9300f2b948710d2653dD7B07f33A8B32118C'

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