AMLRun KYT on a crypto withdrawal

Screen an outbound crypto transaction with the KYT API before broadcast, read the allow/review/block decision, and store the response for the audit trail.

ComplianceBuild a crypto sanctions screening check

Call the sanctions endpoint to test a crypto address against sanctions lists, read the match result and list name, and record the check for compliance evidence.

ComplianceOnboard a VASP customer with AML checks

Run sanctions and risk screening on a VASP customer wallet at onboarding, set an initial risk level, and store the baseline for ongoing monitoring and audit.

AMLSet AML risk thresholds

Map the risk score returned by the AML API onto allow, review, and block bands, tune thresholds against your risk appetite, and keep the mapping auditable.

AMLDetect mixer exposure

Use the risk score exposure array and a fund-flow trace to detect mixer proximity for an address, measure hop distance, and record the finding for audit.

AMLScreen a counterparty before payout

Screen a payout destination with sanctions and risk checks before releasing funds, gate the release on the result, and store the decision for the audit trail.

ComplianceAutomate suspicious activity triage

Turn KYT review decisions into a triage queue, enrich each item with a risk score and fund-flow context, and store the evidence needed for a SAR.

ComplianceCheck a crypto address against OFAC

Query the sanctions endpoint to test a crypto address against the OFAC SDN list, read the match and list name, and store the result as compliance evidence.

AMLMonitor a wallet for ongoing risk

Rescreen a wallet on a schedule with the risk and sanctions endpoints, compare against the stored baseline to detect drift, and record each check for audit.

AMLExplain an AML risk score

Read the AML risk response field by field: score, risk_level, confidence, and the exposure array, so an analyst can justify a decision and store the evidence.

AMLHandle a high-risk crypto deposit

Detect a high-risk incoming deposit with the risk endpoint, trace its inbound flow to confirm the source, hold funds, and store the evidence for audit.

ComplianceBuild a crypto Travel Rule workflow

ProcessingCreate a Wallet and Derive Addresses

Create a wallet with the 1st Node API and derive per-user deposit addresses across eth, btc and tron. Non-custodial by default so you keep key control.

ProcessingSimulate a Transaction Before Sending

Simulate any raw transaction with the 1st Node API to catch reverts and fee shortfalls before broadcast. Returns balance changes and revert reason across chains.

ProcessingSweep Deposits to a Treasury

Sweep collected deposits from per-user addresses into one treasury with the 1st Node API. Simulate first to catch fee shortfalls on eth, btc and tron.

ProcessingSend a Mass Payout

Send a batched crypto mass payout with the 1st Node API. One call fans out to many recipients on tron, eth or btc — simulate first to avoid fee shortfalls.

ProcessingManage TRON Energy for Cheap Transfers

Stake, delegate or rent TRON energy with the 1st Node API to cut TRC-20 (USDT) transfer costs. Provision energy before sweeps and payouts to avoid burning TRX.

ProcessingEstimate and Set EVM Gas Fees

Estimate EVM gas fees with the 1st Node API and set maxFeePerGas correctly before broadcast. Simulate first to catch fee shortfalls and reverts on eth.

ProcessingDetect an Incoming Deposit

Detect incoming crypto deposits with the 1st Node API by polling GET /v1/deposits or subscribing to a webhook. Covers eth, btc and tron addresses.

ProcessingRevoke a Risky Token Approval

List ERC-20 approvals with the 1st Node API and build a revoke transaction for risky spenders. Simulate before broadcast to confirm the allowance drops to zero.

ProcessingBroadcast a Raw Signed Transaction

Broadcast a raw signed transaction with the 1st Node API on eth, btc or tron. Simulate before broadcast to catch reverts and get the hash back to track.

ProcessingEstimate TRON Bandwidth and Energy

Estimate TRON bandwidth and energy with the 1st Node API before sending. Size rented or delegated energy so TRC-20 (USDT) transfers clear without burning TRX.

PaymentsIssue a crypto invoice

Create a crypto invoice in one call: post an amount in USD, list the chains you accept, and get back a pay-to address, checkout URL and invoice id.

PaymentsVerify a payment webhook signature

Never trust a payment webhook until you verify its HMAC-SHA256 signature: recompute the digest over the raw body and reject any mismatch before crediting.

PaymentsHandle underpayment and overpayment

Buyers rarely send the exact amount. Read the underpaid and overpaid webhook statuses, then top up, refund the excess or credit — without double-crediting on retries.

PaymentsRefund a crypto payment

Return funds against a settled invoice with one call: post a full or partial refund to the invoice id and track the on-chain payout back to the buyer.

PaymentsSettle a payment to fiat terms

Price and account for crypto checkout in fiat: the invoice locks a USD amount, the settled webhook confirms it, and payouts move funds on your schedule.

PaymentsAccept USDT on TRON

Take TRC-20 USDT payments on TRON: create a tron invoice, rent energy to keep transfer fees low, and settle against the built-in price layer.

PaymentsReconcile payments with on-chain data

Close the loop on checkout: match settled invoices against the address transfer history so every credited order maps to a confirmed on-chain deposit.

Market dataValue a wallet in fiat

Get a wallet's total USD value in one call: the net-worth endpoint prices every balance through the built-in price layer, so no separate market-data vendor.

Market dataGet token metadata and supply

Fetch a token's name, symbol, decimals and supply in one cheap C1 read — the reference data you need to display and format on-chain amounts correctly.

Market dataBuild a token price chart

Render a price chart from OHLCV candles: request an interval and window from the cheap C1 OHLCV endpoint and cache the series to keep credit use low.

Market dataList top holders of a token

Pull a token's largest holders in one call: the holders endpoint returns ranked addresses and balances so you can measure concentration and whale exposure.

Market dataGet DEX pool and TVL data

Find the DEX pools for a token and read their TVL in one call: rank liquidity venues to size slippage and route trades against the deepest pool.

Market dataBacktest with historical OHLCV

Feed a strategy backtest from historical OHLCV: page candles by interval and window from the cheap C1 endpoint, then cache the series for repeated runs.

IntelligenceLabel a wallet with entity data

Resolve any address to a cluster-level entity, category and confidence with one REST call, then store the label so every downstream decision is reproducible.

IntelligenceRead a counterparty graph for an address

Pull the labeled counterparty graph for any address — who it sends to and receives from, with entity labels and volumes — as structured data you can store.

IntelligenceFind wallets related to an address

Surface addresses likely controlled by the same entity as a target — with a relation type and confidence — and store the set for reproducible investigations.

IntelligenceTrack smart money netflow for a token

Read net inflow and outflow from smart-money wallets for a token or a single address, returned as numbers you can store, chart and combine with trading data.

IntelligenceCluster addresses into entities

Resolve an address to its cluster and the entity that cluster is attributed to, with heuristics and confidence, then store the mapping for reproducible analysis.

IntelligenceBuild an on-chain investigation

Assemble labels, counterparty graph and a multi-hop fund-flow trace into one reproducible investigation you own, then attach AML risk on the same API key.

IntelligenceDetect a bridge transfer in a fund flow

Trace funds across hops and spot when a path terminates at a bridge entity — the signal that value left the chain — then continue the trace on the destination.

IntelligenceScore a token for risk

Get a structured risk profile for a token contract — holder concentration, liquidity and contract flags with a score and confidence — and store it for reuse.

IntelligenceMonitor whale movements for a token

Watch large holders move a token by polling smart-money netflow and per-address netflow, labeling the movers with entity data, and storing every signal you fire.
