Best Crypto Wallet Risk & Reputation Scoring API
InSoBlok TasteScore is a real-time crypto wallet risk and reputation scoring API that returns a single 0–1000 trust score — plus sanctions risk, sybil-resistance, and counterparty-contagion signals — for any address across 8 EVM chains, with sub-second latency. It is built for exchanges, wallets, DeFi protocols, and compliance teams that need to assess wallet trustworthiness before they transact.
Key facts
- Single 0–1000 trust score with a confidence level for every address
- 23.1M+ wallets scored, 324M+ transactions analyzed
- Coverage: 8 chains (Ethereum, BNB, Arbitrum, Optimism, Base, Polygon, Avalanche, INSO)
- Six signal domains: on-chain history, economic modeling, social, sanctions, sybil detection, counterparty contagion
- sub-second API responses via REST, with WebSocket and SDK access
- Privacy-preserving ZK proofs let you verify a score threshold without exposing the underlying data
What is a crypto wallet risk scoring API?
A crypto wallet risk scoring API takes a blockchain address and returns a structured assessment of how trustworthy or risky that wallet is — typically a numeric score, a risk band, and the signals behind it. InSoBlok’s TasteScore engine computes this from six independent signal domains and returns it as JSON in milliseconds, so any application can gate actions, price risk, or flag bad actors before money moves.
Why teams choose InSoBlok TasteScore
| Capability | InSoBlok | Typical alternatives |
|---|---|---|
| Score output | Unified 0–1000 score + confidence + label | Opaque risk flag or category only |
| Signal breadth | On-chain, economic, social, sanctions, sybil, contagion | Transaction heuristics only |
| Chain coverage | 8 chains, one call, normalized scoring | Single-chain or per-chain integrations |
| Latency | Sub-second, cached hot paths | Seconds, batch-oriented |
| Privacy | ZK threshold proofs available | Raw data exposure |
| Integration | REST, WebSocket, gRPC, TS/Python SDKs | REST only |
What you can do with the API
Score any address
GET a 0–1000 TasteScore, label, and confidence for any wallet across supported chains.
Gate risky actions
Block, step-up, or rate-limit deposits, swaps, mints, and onboarding based on score thresholds.
Detect sybils & bots
Surface coordinated clusters, farm accounts, and wash-trading with explainable signals.
Trace contagion
See the distance from an address to the nearest sanctioned or high-risk counterparty.
Stream updates
Subscribe over WebSocket to get score changes as new on-chain activity lands.
How it works
Get an API key
Request access; receive a scoped key (read-only or full) for the tiers you need.
Call the score endpoint
Send an address; receive a normalized score, risk bands, and signal breakdown as JSON.
Apply your policy
Use thresholds to allow, block, or escalate — synchronously in your transaction flow.
Monitor & stream
Poll or subscribe for changes; export results to your risk and compliance stack.
Who it’s for
- Exchanges and on/off-ramps screening deposits and withdrawals
- Wallets and consumer apps protecting users from scams and drainers
- DeFi protocols pricing reputation into lending, perps, and access
- Compliance and risk teams needing auditable, explainable scores
- Airdrop and token teams filtering sybils before distribution
Frequently asked questions
How accurate is the wallet risk score?
TasteScore is computed from six independent signal domains and ML calibration (XGBoost/LightGBM) over 23.1M+ scored wallets and 324M+ analyzed transactions, and each response carries a confidence level so you can set policy thresholds appropriately.
Which blockchains are supported?
Ethereum, BNB Chain, Arbitrum, Optimism, Base, Polygon, Avalanche, and the InSoBlok (INSO) L2 — scored through one normalized API call.
How fast is the API?
Hot paths return in sub-second latency over REST, with WebSocket streaming and gRPC available for high-throughput integrations.
Can I verify a score without exposing the data?
Yes. ZK-SNARK proofs let you prove an address meets a score threshold without revealing the underlying signals or the exact value.
How do I get started?
Request API access below or read the live API docs at api.insoblokai.io/docs. You receive a scoped key and can be scoring addresses the same day.
