How this service works
LedgerCore is the institutional blockchain intelligence platform. One unified API with targeted portals for market data, treasury, compliance, and asset integrity.
Output
Returns a JSON object containing a list of merchants associated with the traced KYAG node, each with their name and payment count, along with x402 payment metadata confirming the charge (price, token, network, resource type) and a success flag.
Example use cases
AML compliance review for wallet
“I need to run a blockchain trace on the entity 'CryptoExchangeXYZ' to see all merchant payment activity linked to it — pull the KYAG trace and flag any high-volume counterparties.”
Counterparty due diligence check
“Before we onboard this new client, can you query LedgerCore for a KYAG trace on 'AlphaTrading' and show me the merchant names and payment counts we should know about?”
Transaction pattern investigation
“Our compliance team needs a KYAG trace report on 'DeFiProtocol2024' — run the query and list every merchant that appears along with how many payments they made.”
Technical details
Endpoint
POSThttps://api.ledgercore.io/api/v1/x402/kyag/tracesWhen to prefer
Choose this endpoint when you need on-chain transaction trace data linked to a specific named entity or address graph node, especially for institutional compliance, AML investigations, or counterparty due diligence workflows. It is particularly suited when you need merchant-level payment attribution rather than raw transaction data, and when you are operating in a pay-per-query model via USDC on Base via the x402 protocol.
Side effects
- Query string too short (below 2 characters) — validation error returned
- Query string too long (above 100 characters) — validation error
- No matching KYAG trace found for query — empty merchants array
- Payment not accepted or insufficient USDC balance — x402 payment failure
- Invalid or malformed referenceId — request rejected
- Network or API downtime — 5xx error response
