How this service works
Pay-per-request identity, risk, authorization, execution-preflight and evidence APIs for autonomous agents.
Output
A JSON object containing a risk score and associated data for the queried blockchain address, sourced from the BlockchainSecurity Atlantis service. Includes upstream request ID, credit metadata, and the raw risk data payload in the `upstream_response.data` field.
Example use cases
Pre-transaction wallet screening
“Before I send 5 ETH to 0xAbCd1234...5678, can you check the risk score for that Ethereum address to make sure it's not flagged for fraud or sanctions?”
DeFi contract due diligence
“I'm about to interact with this Ethereum smart contract at 0xdAC17F958D2ee523a2206206994597C13D831ec7 — can you pull a risk score on it so I know if it's considered high risk?”
Tron address compliance check
“Can you run a risk assessment on this Tron address TN3W4H6rK2ce4vX9YnFQHwKENnHjoxb3m1 for me? I need to know its risk level before onboarding it as a vendor.”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/bcs/address-riskWhen to prefer
Use this endpoint when you need a risk score specifically for Ethereum or Tron addresses and are operating in an x402 micropayment environment. Prefer this over manual on-chain analysis when you need a quick, structured risk signal for compliance screening, fraud prevention, or due diligence before transacting. Note: only supports Ethereum and Tron chains.
Side effects
- Invalid or missing `address` parameter returns a 400 error
- Unsupported blockchain (not 'ethereum' or 'tron') returns a validation error
- Payment failure (x402) if USDC balance is insufficient — returns 402 Payment Required
- Address not found or unscored by upstream service returns empty data
- Rate limit exceeded from upstream BlockchainSecurity service
