Recommended contract

POST https://api.nzochain.com/api/v1/wallets/risk
X-API-Key: YOUR_API_KEY
Content-Type: application/json

{"wallet":"0x...","network":"ethereum"}

Minimum scope: wallet.scan. Networks: ethereum, bnb, polygon, arbitrum (4 EVM). Solana is not supported.

v1 Endpoints

  • Wallet risk: POST /v1/wallets/risk — Free (hard cap 1,000 calls/month).
  • Contract risk: POST /v1/contracts/risk — Free.
  • Analyze / Simulate: POST /v1/transactions/analyze and .../simulate — Starter+. Live simulation depends on Tenderly.
  • Threat check: POST /v1/threats/check — Growth+.

Honest limits

  • Free: hard cap → HTTP 429 RATE_LIMIT (no paid overage).
  • Starter / Growth / Business: overage billed up to 3× quota; then 429 HARD_CEILING.
  • Live webhook: only revocation.completed.
  • Legacy: POST /api/risk/scan exists for compatibility — not the recommended integration.
