Findet Betraege in Freitext, deutet deutsche und englische Tausender- und Dezimaltrennung richtig, loest Mio, Mrd, Tsd und k auf, erkennt 50 Waehrungen an Symbol, Code oder Wort einschliesslich USDC und Bitcoin und liefert Zahl, Waehrungscode, kleinste Einheit und Fundstelle getrennt. Rechnet bewusst nicht um.

Verdict Wallet Screen — check any Bitcoin or Ethereum/EVM wallet address against the US Treasury OFAC SDN sanctioned digital-currency-address list. Returns sanctioned true/false + matched list. Real OFAC data, keyless — the on-chain compliance gate for payment, DeFi and fraud agents. $0.02.

Services whose inbound USDC transfer count and inflow are growing across comparable daily windows. The response states how many calendar days of history actually back the comparison. Use this to spot rising demand early. Growth is measured on observed on-chain transfers, not on self-reported revenue.

Bitcoin chain-tip orphan + valid-fork stream (10min cadence). For exchange confirmation-policy tuning, cross-chain bridge safety windows, finality auditors. branch_length >= 2 = unusual reorg risk.

USD Coin

Track capital flows from high-volume DEX participants.

Address label/classify on Base/Ethereum: contract-vs-EOA + code presence (+ENS). Onchain USDC pay-per-call.

For a given chain, token pair and input amount, every connected DEX is queried through its own contracts: Uniswap V3 through the Quoter via eth_call across all fee tiers, constant-product pools through the pool maths on live reserves, Solidly-style pools through their own getAmountOut. Two-hop routes through the wrapped native token and the chain USDC are included, priced by chaining the hops exactly as a real swap would traverse them. Nothing is executed, submitted or handed to a router — every

Screen a crypto wallet address against global sanctions and illicit-activity intelligence. Cross-checks the on-chain Chainalysis sanctions oracle, TRM screening, OFAC SDN and GoPlus address flags (mixer, phishing, laundering), returning a sanctioned yes/no, matched lists and an AML risk score. Use it for AML compliance, sanctions screening and KYT before onboarding or paying an address. Ed25519-signed. 0.005 USDC on Base.

Reads one transaction hash on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain and answers the question an agent actually has: did it go through, is it final yet, and what did it cost. Finality is defined differently per chain, so the rule used and the required block count are part of the answer instead of a single hard-coded number. A hash that no node knows is reported as "unbekannt", never as "fehlgeschlagen" — the two are not the same. A pending transaction whose nonce has alre

Reads the receipt of a transaction on Ethereum, Base, Base Sepolia, OP Mainnet, Arbitrum One, Polygon PoS or Avalanche C-Chain and compares it with what you expected to be paid. The comparison runs against the ERC-20 transfer events in the receipt, not against the transaction recipient, because in a token payment the transaction recipient is the token contract and never the seller. Returns every transfer event with sender, recipient, token, raw amount and human amount computed with that token de

Resolves pool, price oracle and data provider through the protocol address provider rather than hard-coded addresses, then reads every reserve the wallet touches: collateral amounts, variable and stable debt, LTV, liquidation threshold, liquidation bonus and the borrow rate, all at one block. Values are computed with the price the protocol oracle reports, not with a market price from an exchange — a liquidation follows the oracle, and the oracle source contract per asset is named in the answer s

FULL-UNIVERSE cascade scan: ~600 USDT perps across Bybit+OKX+Binance. Bybit is the only complete unthrottled liquidation tape in crypto and no exchange publishes history of it

Transaction fund-flow tracing with ML-powered anomaly detection across 8 live chains (Bitcoin, Ethereum, Polygon, Base, Arbitrum, Optimism, Avalanche, Solana; BNB Smart Chain on Enterprise rollout). Returns multi-hop graph, counterparties, and risk classification.

Everything a Base address holds, valued in USD: ETH plus its ERC-20 tokens, largest first, with a spam floor you set

Create a bank payout recipient for a crypto off-ramp (sell USDC, cash out to fiat). Provide the target currency, account type and bank details (see /requirements), the account holder legal name, and the funding wallet. Returns the recipient id for /transfer. The recipient is sanctions-screened upstream. Pay 0.01 USDC.

Validates a UserOperation structurally and against chain state. It computes the required prefund from the gas limits and fee fields, reads the sender deposit on the EntryPoint and, when a paymaster is set, that paymaster deposit and stake, and says plainly whether the operation is funded. The nonce is read from the EntryPoint and compared with the one supplied, so a stale nonce is caught before submission.

Reads a Safe from the public transaction service and returns what decides whether it can act: the owner set, the threshold, the current nonce, any enabled modules and the guard contract, and the master copy version. Queued transactions are listed with the confirmations they already carry and the number still missing, so it is visible which of them are one signature away from executing.

Read a normalized source owned by the paying wallet.

GitHub developer activity for any crypto project — commits, stars, forks, PRs, code additions/deletions via CoinGecko.

Resolves a pool either by address or by chain, token pair and DEX, then reads token0, token1, fee tier, reserves, in-range liquidity and the current tick straight from the contract. Exit impact is not estimated from a formula but simulated: for Uniswap V3 through the official Quoter contract via eth_call, which walks the same ticks a real swap would and reports how many it crossed; for constant-product and Solidly pools through the pool maths or the pool own getAmountOut. Nothing is ever execute

Answers the question that stands before every signature: what really happens to my assets and my rights. The call is executed against the state of a named block on a simulation interface, never on the chain — this hub holds no private key and broadcasts nothing. Balance changes are not inferred from events but measured: the same simulation reads every touched balance immediately before and immediately after the call, native currency included, so an outflow that emits no event is still visible. A

Wallet funding QR for your human: pass asset (usdc-base, tao, eth, sol, btc, ...), amount and destination wallet - get a prefilled Apple-Pay-capable onramp link (MoonPay) plus the QR as base64 PNG, ready to forward. Provider minimums enforced, address format validated. The purchase settles directly with the licensed onramp; this service never touches funds.

Returns the current fee rates for the usual confirmation targets together with the state of the mempool behind them, and then does the part that is usually missing: it estimates the virtual size of the transaction you describe and computes the resulting total fee in satoshis for each target.
