Pre-trade token safety check for AI agents. Simulates a sell before you buy, then returns one low/medium/high/unknown verdict with the signals behind it: sellability, buy/sell tax, liquidity depth, pair age, same-ticker impersonation, owner powers from bytecode. Ethereum, BSC, Base, Solana. Fail-closed - a check that cannot run answers unknown, never low. Publishes its own measured error rate with the benchmark harness in the repo. Free, no signup, no API key, MIT.
Best-route swap quotes, token search and USD prices across EVM chains. Read-only, never trades.
Live Base Mainnet on-chain data (gas, DEX, Aave, token risk, prices). Pay per call in USDC via x402.
Real-time non-custodial cryptocurrency swap rates, fee calculation, and direct routing parameters across 240+ multi-chain pairs (BTC, XMR, SOL, TON, USDT).
Pay-and-anchor a hash or AI decision log on Cardano (CIP-0190). Non-custodial. MCP-native. Mainnet.
353 tools: balances, blocks, gas, txs and logs on 5 EVM chains, plus Bitcoin. 25 free calls.
Timestamped proof that AI outputs and data existed, anchored on the Privi blockchain.
Screen a new token for red flags and keep signals, and find a wallet's self-declared public name.
Rug-risk verdict for any Base ERC20 by contract address: 0-100 score, A-F grade, graded checks (ERC20 shape, honeypot selectors, DEX liquidity, market) plus an ungraded admin-powers profile (proxy, owner, mint, blacklist, pause) with raw evidence. Deterministic, no LLM. Pay-per-call via x402 ($0.01 USDC on Base); initialize and tools/list are free.
Solana swaps with local signing, confirmed receipts, trading volume and filtered live trade data.
Live Base Mainnet on-chain data (gas, DEX, Aave, token risk, prices). Pay per call in USDC via x402.
Pay-per-call MCP tools for agents, settled with x402 (USDC on Base mainnet). 17 tools — text/data utilities plus x402/EVM-native: decode an x402 challenge, verify a settlement receipt on-chain, EIP-712 typed-data hashing, ABI encode/decode, Merkle-proof verify, keccak256, and EIP-55 address checks. No API keys.
58 pay-per-call tools for AI agents: balances, tokens, blocks, gas, transactions, receipts, nonces and logs on Base, Ethereum, Arbitrum, Optimism and Polygon, plus Bitcoin fees and addresses, Lightning invoices and ENS. USDC via x402.
A marketplace for AI agents. Tools and data for agents, on one MCP address. No account, no API key.
AI agents that watch DeFi positions: read a wallet report, draft agents for the owner to sign.
Read-only data on Arc, Circle's blockchain, from Registrai: apps on Arc with their stablecoin payments (USDC, EURC), paying wallets and volume; the Arc ecosystem directory (258 projects with status, launch date and sources); Arc chain figures (USDC supply, TVL, daily transactions); and the hourly Arc indices.
