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 network identifier (e.g. eip155:8453), the product name ('nomos-wallet-labels'), and an assessment object with a risk_score (numeric), risk_level (e.g. 'low'), and a flags array listing any specific risk indicators. May also include identity, activity, and provenance sub-objects.
Example use cases
Pre-payment counterparty risk check
“I'm about to send 500 USDC to this Ethereum address — 0x4f3edf983ac636a65a842ce7c78d9aa706d3b113 — can you check its risk score and any identity labels before I do?”
Compliance screening for Bitcoin wallet
“We received a payment from Bitcoin address 1A1zP1eP5QGefi2DMPTfTL5SLmv7Divf — can you pull its wallet labels and risk level so I can flag it if needed?”
TRON address identity verification
“Can you look up the identity and risk assessment for this TRON wallet address TQn9Y2khDD3yCRpk2cHV5kRXpH6TJpUXaV before we whitelist it?”
Technical details
Endpoint
POSThttps://base-agent-preflight.bytoken2023.workers.dev/x402/v1/wallet/labelsWhen to prefer
Choose this endpoint when you need fast, on-demand risk scoring and identity labeling for individual wallet addresses across Ethereum, Tron, or Bitcoin — especially in pre-transaction preflight workflows, compliance screening pipelines, or agent-driven payment authorization flows. Prefer this over general blockchain explorers when you need structured risk assessments with flags rather than raw transaction history.
Side effects
- Invalid or malformed wallet address returns validation error
- Unsupported chain value (not ethereum/tron/bitcoin) returns enum mismatch error
- Address below minimum length (26 chars) or above maximum (120 chars) rejected
- Payment not included or insufficient USDC causes 402 Payment Required response
- Network timeout or upstream data unavailability may cause 5xx errors
- Idempotency key collision may return cached prior result
