Counterparty due-diligence for any Base or Ethereum wallet — age, funding origin, USDC flow, activity pattern, and risk flags in one scored report. The domain-report of wallets: wallet age, first funder, in/out totals, distinct counterparties, 30d activity shape, contract-or-EOA, score + A–F grade. An empty or fresh wallet is a real answer (low score + flags). 5min cache.
Full profile for any ERC-20 token by contract address — name, symbol, decimals, supply from the chain itself, plus live price, liquidity, and volume from DEX data — Base and Ethereum, no API key. Holder count included; identity read on-chain so it can't lie or be rate-limited away. 10min cache; unlisted tokens return nulls with a no_dex_liquidity finding.
One-call market briefing for agents — BTC/ETH/SOL spot + 24h moves, major fiat crosses (USD/EUR, USD/GBP, USD/JPY, EUR/GBP), Base and Ethereum gas with USD transfer cost, and the crypto fear/greed index. Four sections fetched concurrently with graceful partial failure; any dead section is null with a finding, never a failed call. 60s cache; no API key.
Live gas prices across Base, Ethereum, Arbitrum, Optimism, and Polygon with USD cost estimates for a transfer, an ERC-20 send, and a swap — keyless, one call, all chains. Per chain: gas price + EIP-1559 base/priority fee in gwei, native-token USD price, 15s cache. L2 figures are execution-gas only (L1 data fee excluded, flagged in findings).
Token balance for any wallet — native coin, USDC and any ERC-20 on Base, Ethereum, or Solana, with USD estimates — straight from public RPCs, no API key. Raw units as decimal strings plus formatted numbers; add up to 10 ERC-20 contracts via tokens=. 60s cache; an empty, never-used address is a real answer (zeros + no_activity_detected finding).
Historical OHLC candles for any major crypto asset — hourly or daily, up to 300 candles, with period stats (change %, high, low) — from Coinbase Exchange with Kraken fallback, no API key. Also a price-at-date mode: pass date=YYYY-MM-DD for that day's candle and close. USD, EUR, or GBP quotes; 5min cache.
Crypto prices for up to 25 coins in one call — live cryptocurrency spot prices for BTC, ETH, SOL and more in USD, EUR, or GBP from Coinbase with Kraken and CoinGecko fallback; no API key, one flat price. Per asset: price, 24h change when the source provides it, source, cache age. 30s cache; unknown symbols land in unresolved without failing the call. 25 prices for one $0.005 call vs 25 single-symbol lookups.
