402 services carry this tag in their source record. Tags come from the provider, not from us — a tag is a claim about what the service does, not proof that it does it well.
Pre-sign check for agent wallets. Use when your agent is about to sign a transaction or EIP-712 message: send to and data (or typedData, or untrusted text) and get block, review or allow, with decoded calldata and findin...
Turn a public web page into an LLM-ready document: clean markdown with nav/cookie/script boilerplate removed, parsed JSON-LD, OpenGraph, heading outline, tables, link graph, word and token counts, and embedding-ready chu...
Read the current eth_gasPrice value from a supported public Base, Ethereum, or Arbitrum JSON-RPC endpoint.

Look up the native coin balance (ETH/MATIC) plus every ERC-20 holding for a wallet address on Ethereum, Base, Polygon, Arbitrum, or Optimism. Returns clean decimal balances (already scaled by token decimals) plus symbol...
Fetch a block header by number, hash, or "latest" on Ethereum, Base, Arbitrum, Optimism, Polygon, or BNB Chain: timestamp, miner, gas used/limit, base fee, transaction count, size. Public JSON-RPC, no API keys. POST a JS...
Token verdict / rug check: an A-F safety grade, a one-line verdict and a plain-language take on any token on Base, Ethereum, BSC, Arbitrum, Optimism, Polygon, Avalanche or Solana, with a shareable page and card image. Bu...
SCV Fresh Feed: 25 newest tokens on base with instant risk scores + market data ($0.005 per call, USDC x402)
Current gas prices for Base or Ethereum mainnet: legacy gas price, EIP-1559 base fee and suggested priority fee (all gwei), plus the latest block number. Query: chain (base | ethereum, default base). Real-time from publi...
Look up any EVM chain by chain ID or name (8453, base, arbitrum): chain ID in decimal and hex, native currency, public RPC URLs, block explorers and testnet flag. Use to configure wallets, RPCs or cross-chain apps.
Reference data for a blockchain by its chainId: name, gas/native token, block explorers, number of public RPCs and website. Utility for multi-chain agents. Live from chainid.network (ethereum-lists, open data).
Encode a contract function call (calldata) from its signature and arguments, e.g. transfer(address,uint256) with [to, amount]: selector and hex data ready to sign or simulate.
Keyless public RPC endpoints (HTTPS and WebSocket) of any EVM chain by name or chainId, with block explorers, native currency and website. Lets an agent connect to any chain.
Inspect any Ethereum address: EOA vs contract vs EIP-7702 delegated, ETH balance, nonce, proxy implementation (EIP-1967/1167/zos), and ERC-20 name/symbol/decimals/supply.
Check a Ethereum wallet's ERC-20 approvals: allowances for 8 major tokens (USDC, USDT, WETH, DAI...) to common spenders (Permit2, Uniswap Universal Router v4, Uniswap Universal Router, Uniswap SwapRouter02...); flags unl...
Live feed of freshly-detected malicious addresses on Base — address-poisoning seeders caught via zero-value transfer sprays, updated continuously by our on-chain collector. Poll ?since=<unix> to ingest only new threats i...
Decode an EVM signature request (EIP-712 typed data, Permit/Permit2, or ERC-20 approve calldata) into a structured intent: what token, which spender, how much, until when, plus risk_flags and an action_hint. Deterministi...
Retrieve a live EVM block header and a bounded list of real transaction hashes by height, tag, or block hash.
