How this service works
Paste any Base or BNB Chain address before you pay or hire it. ChainWard tells you Pay or Hold, and why, from the wallet’s on-chain history. Free.
Output
A CSV file containing on-chain risk and history data for seller/wallet addresses on Base or BNB Chain, including risk verdicts (Pay or Hold), behavioral signals derived from blockchain transaction history, and metadata useful for screening addresses before payments.
Example use cases
Bulk screening before agent payouts
“I have a list of Base chain wallet addresses I'm about to pay — can you download the ChainWard sellers dataset CSV so I can check all their on-chain risk flags before sending anything?”
Freelancer vetting before hiring
“I want to hire a contractor who gave me their Base wallet address — can you grab the ChainWard Base seller data file so I can see their on-chain history and decide if it's safe to pay them?”
Automated payment pipeline risk check
“Before my agent sends payments to the seller wallets on Base this week, pull the ChainWard sellers CSV dataset so the pipeline can filter out any 'Hold' addresses automatically.”
Technical details
Endpoint
GEThttps://api.chainward.ai/api/paid/x402-sellers-base/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need bulk or file-based access to ChainWard's on-chain risk data for multiple seller addresses at once, rather than checking a single address interactively. Ideal for automated payment pipelines or agent workflows that need to ingest a CSV of risk data for downstream filtering. Use the per-call address check endpoint for single-address lookups at lower cost ($0.05 vs $10).
Side effects
- Payment of $10 USDC not completed — endpoint returns 402 Payment Required
- Invalid or missing properties parameter — returns 400 Bad Request
- Address not found on supported chain — returns empty or partial dataset
- Network timeout on large dataset retrieval — request may need retry
- Unsupported chain specified — only Base and BNB Chain are supported
