ChainWard On-Chain Risk Check for Base Address is a paid API for AI agents from api.chainward.ai, paid per call via x402, $10/call, status unknown (last checked 2026-10-10).
Returns a CSV report of every provable on-chain risk flag (dormant wallets, stranded USDC, concentrated counterparties, factory clones, unverified claims) for a given Base address, with each flag tied to its transactions.

How this service works
Check a Base or BNB Chain address before your agent pays it ($0.05), see where an x402 or agent-marketplace seller's buyers get their stablecoins, on either chain ($0.10), or buy the dataset behind a published decode ($10). Paid in USDC on Base over x402; a check that fails is never charged.
Output
A CSV file containing structured risk flags for the queried Base address. Each row maps a specific risk type — such as dormant wallet, stranded USDC, concentrated counterparty, factory clone, or unverified on-chain claim — to the relevant transaction hashes that prove it. Flagged reports are attested on Base. No overall safety verdict is provided.
Example use cases
Pre-payment wallet due diligence
“Before I send USDC to 0xAbCd...1234 on Base, can you pull a ChainWard report on that address and flag anything suspicious — dormant activity, factory clones, or claims the chain doesn't support?”
DeFi protocol counterparty audit
“I need to audit the Base address 0xDeFi...5678 we're about to integrate with — run ChainWard on it and show me if there's any counterparty concentration or stranded USDC I should know about.”
Smart contract clone detection
“Can you check Base contract address 0xFactory...9999 with ChainWard and see if it's flagged as a factory clone or has any unverified on-chain claims tied to specific transactions?”
Technical details
Endpoint
GEThttps://api.chainward.ai/api/paid/%7Bslug%7D/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need transaction-backed, provable on-chain risk flags for a specific Base address — particularly for due diligence before sending funds, auditing counterparties, or detecting cloned contracts. It is distinct from general blockchain explorers in that it surfaces specific risk categories (dormant wallets, stranded USDC, factory clones, claim mismatches) rather than raw transaction history, and attests flagged reports on-chain. Prefer it over manual block explorer review when you need structured, agent-consumable risk data in CSV format.
Side effects
- Invalid or malformed Base address slug returns an error or empty report
- Address with no detectable flags returns an empty CSV
- Payment not fulfilled results in HTTP 402 response blocking access
- Slug path parameter missing or malformed leads to 404 or bad request
- Temporary API unavailability returns 5xx error
