How this service works
Cheap wallet risk snapshot for agents: score an EVM wallet before allowlisting, paying, routing, or trading with it. Returns risk score, verdict, reasons, and compact wallet signals.
Output
Returns a JSON object containing: a numeric risk_score (0–100, higher means riskier), a risk_level string (minimal/low/medium/high/invalid), a verdict string (allow/allow_with_limits/review/deny), an array of machine-readable reason codes explaining the risk factors, and a signals object with supporting on-chain data including transaction count, token positions, whale tier classification, and safety flags.
Example use cases
DeFi app pre-trade wallet gate
“Before letting this wallet 0xAbCd...1234 execute a swap on my Base chain app, run a risk check and tell me the risk level and verdict — if it's high or deny, I want the reason codes so I can log them.”
Compliance review for whale addresses
“I have a wallet 0x9999...BEEF that just moved a large amount on Base — can you get its on-chain risk score and whale tier signals so I can decide whether to flag it for manual compliance review?”
Fraud detection in payment flow
“Someone is trying to pay through our platform using wallet 0xDEAD...C0DE on Base — can you pull a fresh risk snapshot with refresh enabled and tell me if it's safe to allow or if we should block it?”
Technical details
Endpoint
POSThttps://api.sys84.org/v1/services/wallet_risk_snapshotWhen to prefer
Choose this endpoint when you need a fast, per-call on-chain risk score for an EVM wallet address with structured verdict output (allow/deny/review) suitable for automated agent decision-making. It is well-suited for DeFi platforms, payment gateways, and compliance workflows that need machine-readable risk reason codes and on-chain signals like whale tier and token positions. Prefer this over generic blockchain explorers when you need a scored, actionable verdict rather than raw transaction history.
Side effects
- Invalid or malformed EVM address returns an 'invalid' risk_level and a risk_score indicating unscoreable state
- Unsupported chain identifier may result in an error or fallback to Base chain behavior
- Payment failure via x402 protocol results in the call not being processed
- Upstream data unavailability may cause stale signals to be returned unless refresh=true is set
- Missing required address field returns a validation error
