Crypto price check: the current spot price of Bitcoin (BTC), Ethereum (ETH), Solana (SOL) or any token ticker in USD, cross-checked across five exchanges (Coinbase, Kraken, OKX, Binance, CoinGecko). Returns the median price, the spread between venues and a divergence flag, as a signed price oracle attestation your agent can cite. Use it before your agent trades, quotes, values a portfolio or settles on a token price. Needs at least two live quotes; a ticker no venue lists is not charged.

Ethereum mainnet balances of an address at the latest block, read directly from a full node: ETH plus USDC, USDT, DAI, WETH, WBTC, stETH, LINK and UNI (zero balances omitted). Use it to check a wallet before a payment, for treasury overviews or to verify a deposit. No indexer and no tracking; one address per call.

On-chain spot price of ETH or BTC in USDC from the deepest Uniswap v3 pools on Ethereum mainnet, read from a full node at the latest block (no third-party price feed). Pairs: ETH-USDC, BTC-USDC. Use it as an independent, verifiable price reference; it reflects the pool price, not an exchange average.

Resolve ENS on Ethereum mainnet from a full node: name to address (e.g. vitalik.eth) or address to primary name (reverse record, verified forward). Use it to turn human-readable names into payment addresses and to label addresses. Give either name or address.

Ethereum mainnet gas now, from an independently operated full node: latest block, base fee and the priority fees paid in the last 20 blocks (10th, 50th, 90th percentile), with a suggested max fee for slow, normal and fast inclusion in gwei. Use it before sending a transaction or to time on-chain activity.

Complete wallet snapshot in one call: native ETH balance (wei + human) + USD, USDC balance, nonce/activity and whether the address is a contract.

Complete token due-diligence for a base ERC-20 in one call: metadata, safety score, liquidity, volume and an agent-readable summary. Replaces several separate lookups.

Native ETH balance (and live USD value) for any base address.

Live price, liquidity, 24h volume and DEX pairs for any base ERC-20 token, plus on-chain name/symbol/decimals. Live, per request.

USDC/USDT/DAI balances for a base address (one call, all canonical stablecoins).

Current base gas price (gwei + wei) and the estimated cost of a 21k native transfer.

Header + summary for a base block by number (or "latest"): hash, timestamp, tx count, gas used and base fee.

Everything about a base ERC-20 in one call: on-chain metadata (name/symbol/decimals/totalSupply), price, liquidity, 24h volume, DEX pair count and fdv/marketCap when available.

Concentration / activity radar for a base ERC-20. ERC-20 holder lists are NOT available from a keyless RPC, so this reports DEX liquidity, 24h volume and trade counts as an activity proxy and states holdersSource honestly. Never fabricates holder numbers.

One call for the whole base picture: chain id, latest block, gas price, native token ETH/USD price and the canonical USDC address. Replaces several separate calls.
