Live Base chain snapshot: latest block, base fee + priority fee (Gwei), current ETH price, and the estimated USD cost of a simple ETH transfer. For agents timing or budgeting transactions.
Lists a wallet's active token approvals — which contracts can spend its tokens, the allowance, USD value at risk and a risk factor (revoke.cash-style). Essential wallet-security check for agents and users.
Computes the 4-byte selector for a function signature (e.g. transfer(address,uint256) → 0xa9059cbb). The inverse of the decoder — useful for agents building or matching calldata.
x402 v2 paid EVM token contract risk API on Base and BSC. For 0.01 USDC, returns EIP-1967 proxy detection, owner control and renouncement status, and block-explorer source-code verification. Built for AI agents, bots, an...
Resolves a 4-byte function selector (e.g. 0x70a08231) to candidate human-readable signatures via 4byte.directory. Accepts a bare selector or full calldata.
Base native balance. Native ETH balance (eth_getBalance) of any 0x wallet address on Base at the latest block, in wei and in ETH. Use to check whether a wallet can pay gas or a transfer; for ERC-20 tokens use base_token_...
Base account nonce. Read the transaction count (nonce) of a 0x address on Base, both confirmed and including pending transactions. Use to build the next transaction or to tell whether an address has ever sent anything; f...
Leading causes of death for any US state or the nation - deaths, share of all deaths and age-adjusted rates for heart disease, cancer, stroke and more
Batch Solana token rug check: up to 10 mints in one paid call (half the per-token price). Same output as /v1/check. Query: ?addresses=mint1,mint2,...
Forward + reverse Basename resolution read from the Base L2 Resolver: turn jesse.base.eth into an address, or an address into its primary Basename. No API key required.
A pre-payment gate for an agent about to send USDC. Screens the recipient (OFAC sanctions, Coinbase/Basename identity, wallet vs contract, fresh-address age) and escalates a fresh or anonymous recipient to STOP once the...
Generate cryptographic random bytes
SendCheck: pre-send verification of any EVM address on one chain (EIP-55 checksum, wallet-vs-contract, outgoing activity, balances, verdict). POST {address, chain}
Read-only JSON-RPC against Ethereum, Base, Polygon, Arbitrum, or Optimism with built-in multi-endpoint failover - one paid call, no node or API key of your own. Prefer the named reads (block-number, chain-info, block-inf...
Trending token pools right now on Solana, or any supported chain via chain= - price, liquidity, 24h volume, price change and pool age
CUDA, driver and Ollama compatibility - GPU support, model memory fit and proof inference uses the GPU
Run a read-only transaction simulation with eth_call and eth_estimateGas against a supported public EVM RPC without signing or broadcasting.
SendCheck: pre-send verification of any EVM address on one chain (EIP-55 checksum, wallet-vs-contract, outgoing activity, balances, verdict). POST {address, chain}

Gas price in the Roundhouse canonical contract: CAIP-2 chain to current base_fee_gwei and as_of. Recurring fee-state primitive for transaction timing and autonomous execution.
Current gas prices on Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain and Avalanche: gas price, base fee, low/medium/high priority fee in gwei, native token USD price and estimated USD cost of an ETH transfer, ERC...
Check a BNB Smart Chain wallet's ERC-20 approvals: allowances for 8 major tokens (USDT, USDC, WBNB, BUSD...) to common spenders (Permit2, PancakeSwap v2 Router, PancakeSwap Smart Router, PancakeSwap Universal Router...);...
Inspect any Base address: EOA vs contract vs EIP-7702 delegated, ETH balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.
NFT metadata for ERC-721 and ERC-1155 tokens on Base, Polygon, Arbitrum, Optimism and Ethereum. Resolves tokenURI through IPFS, Arweave, data: URIs and public HTTPS, and returns the parsed metadata JSON.
