How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object containing the product identifier ('bcs-fund-trace'), upstream service name ('blockchainsecurity-atlantis'), response metadata (request_id, credit_cost, credit_remaining), and the upstream response data object containing traced fund path and transaction items for the queried address.
Example use cases
Investigate suspicious wallet outflows
“Can you trace all outgoing transactions from the Ethereum address 0xDEADBEEF... and show me up to 100 results, filtering for USDT and ETH, with a minimum transfer value of 500?”
Track incoming Bitcoin funds
“I need to trace all incoming fund flows to Bitcoin address bc1qxyz... — go 2 levels deep and show up to 30 results.”
Follow Tron USDT movement path
“Follow the fund trail in both directions from Tron address TXyz123... filtering only for USDT, minimum value 1000, up to 5 levels deep and 200 results.”
Technical details
Endpoint
GEThttps://base-agent-preflight.bytoken2023.workers.dev/v1/x402/bcs/traceWhen to prefer
Choose this endpoint when you need to trace fund flows on Ethereum, Tron, or Bitcoin blockchains with filtering by direction, asset type, and minimum value. It is particularly useful for compliance checks, financial forensics, or following suspicious wallet activity. Prefer this over generic block explorers when you need structured, filterable path data with provenance metadata returned programmatically.
Side effects
- Invalid blockchain slug (not ethereum/tron/bitcoin) returns validation error
- Address format failing pattern ^[A-Za-z0-9:_-]{3,128}$ causes 400 bad request
- Depth outside 1-5 range rejected by schema
- Limit outside 1-999 range rejected
- Address with no on-chain history returns empty data object
- Upstream BlockchainSecurity Atlantis service unavailable causes 502/503
- Insufficient USDC balance for $0.49 call fee causes payment failure
