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 with a letter grade (e.g. 'B'), a numeric risk score (0–100, lower is safer), a trust score (0–100, higher is better), a confidence percentage, and the scoring model version used (e.g. 'kyag-risk-v1'). Also includes x402 payment confirmation metadata.
Example use cases
Pre-payment wallet risk screening
“Before I send 50,000 USDC to wallet 0x4f3edf983ac636a65a842ce7c78d9aa706d3b113 on Ethereum, can you run a KYAG risk check on it and tell me the grade and trust score?”
AI agent compliance vetting
“I need to verify the risk profile of an agent before onboarding it — can you run a KYAG check on agent ID agt_9f2c8d1a3b and give me the full risk and trust scores?”
External platform identity assessment
“We're integrating a counterparty from Coinbase with external ID cb_user_7743 — can you pull a LedgerCore risk grade for them so our compliance team can review before we proceed?”
Technical details
Endpoint
POSThttps://api.ledgercore.io/api/v1/x402/kyag/jobWhen to prefer
Choose this endpoint when you need institutional-grade risk and trust scoring for blockchain wallets, AI agent identities, or external platform accounts — especially when compliance, due diligence, or pre-transaction screening is required. It supports multiple subject types (wallet, agent ID, external ID) in one unified call, making it ideal for multi-context compliance pipelines. Prefer it over generic blockchain explorers when you need a structured risk grade and trust score rather than raw transaction history.
Side effects
- Invalid or malformed wallet address returns validation error
- Unsupported chain identifier causes lookup failure
- Unknown agent ID (missing 'agt_' prefix) rejected by schema validation
- Insufficient on-chain data for low-activity addresses may yield low confidence score
- Payment not accepted or insufficient funds triggers x402 payment failure
- Network or service downtime returns 5xx error
