Top transaction counterparties for an address with entity labels, category, per-counterparty transfer counts and observed flow totals. Reuses a scan of the same address from the last 24 hours when one exists, otherwise runs a fresh scan.

Multi-hop exposure analysis over the ChainAnalyzer graph. Returns direct and indirect exposure grouped by risk tier (mixer, darknet, sanctioned entity, exchange, bridge) plus detected money-laundering patterns such as layering and structuring.

Who is this address? Returns verified entity labels from the ChainAnalyzer known registry (token issuers, exchange hot/cold wallets, protocol deployers, sanctioned entities, mixers) plus a ScamDB hit if the address is a known drainer. TRON addresses also resolve public Tronscan tags. Unreviewed and inferred labels are never returned. 12 chains.

Is this destination a lookalike of an address the sender already trusts? Applies the address-poisoning similarity rule (leading and trailing characters that wallet UIs abbreviate to) between one destination and a caller-supplied list of known-good addresses. Pure string comparison when `known` is given, so it answers in milliseconds and never runs a scan.

AML risk score for a blockchain address. 8 chains live for self-serve x402 (Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana); BNB Smart Chain available on Enterprise rollout. 76+ detection rules, 3-model ML anomaly ensemble (Isolation Forest + AutoEncoder + GraphSAGE).

OFAC / FATF / JFSA sanctions screening for any blockchain address. Returns hit list with sanction list source, designation date, and program code.

OFAC / FATF / JFSA sanctions screening for any blockchain address. Returns hit list with sanction list source, designation date, and program code.

Batch AML screening for multiple addresses (up to 50 per request). 8 live chains + BNB Smart Chain on Enterprise rollout, 76+ detection rules. Ideal for AI agents pre-validating wallet inputs at scale.

Stablecoin issuer supply in one JSON call: pass the issuer as the `slug` query parameter. Returns total and circulating supply per chain, cumulative mint and burn totals, and the 20 most recent issuance / redemption events with transaction hashes. Same numbers as the public issuer page, shaped for agents.

Cheap connectivity-check endpoint. Verifies the full x402 settlement path (signature -> CDP facilitator -> on-chain transferWithAuthorization) for $0.01 so AI agents can validate wallet + network + facilitator wiring before committing to higher-value AML calls.

Sign-time risk verdict for a destination or spender before value moves. Registry + ScamDB lookups plus at most one RPC call (approve spender code check), so it answers in milliseconds instead of running a full scan. Same verdict as the subscription REST API.

Is this stablecoin still on its peg right now? Pass the token contract in the path and its chain as the `chain` query parameter. Returns the latest 15-minute VWAP of real DEX trades per chain, the deviation from par in the token's own peg currency (JPY or USD), and a one-word status (on_peg / watch / dislocated) at 0.5% and 2% thresholds. Reads a daily snapshot only — no external pricing call on the request path.

CoinJoin / mixing transaction detection. Identifies Wasabi, JoinMarket, Whirlpool patterns plus generic peel chains.

Screen every address a single transaction touches. Collects the sender, recipient, token-transfer endpoints and token contracts of one transaction, then checks each against the known registry, seven sanctions lists (OFAC, UK, JP, UN, EU, CA, CH) and the ScamDB drainer database. Returns one verdict: block / review / clear. Much cheaper than a full fund-flow trace because nothing is expanded beyond the transaction itself.

Transaction fund-flow tracing with ML-powered anomaly detection across 12 live chains (Bitcoin, Ethereum, Polygon, BNB Smart Chain, Base, Arbitrum, Optimism, Avalanche, Solana, Kaia, TRON, XRP). Returns multi-hop graph, counterparties, and risk classification.

Wallet clustering and entity resolution via Neo4j graph analysis. Returns related addresses, common-input heuristic clusters, and known-entity tags.
