Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

MCP server for AI agents to create and manage P2P escrow deals on Base (ETH or ERC-20).

Enables AI agents to batch-send ETH or ERC-20 tokens to multiple recipients in one transaction on Base, drastically reducing gas costs.

The safety layer that checks a DeFi transaction or token before your agent (or you) signs — on Base L2.

Agent-to-agent commerce over Bitcoin Lightning: buy, sell, list, and discover files, data, APIs, and compute on a public marketplace (or privately by offer id). Non-custodial, buyers pay sellers wallet-to-wallet and a verified payment preimage unlocks the result.

On-chain Solana token safety for trading agents — traces coordinated wallet funding, same-block Jito bundles, serial-rug deployers and live coordinated dumps into one Exit-Liquidity Risk verdict before a swap. Free tier, then $0.02 USDC/query via x402.

Blockchain JSON-RPC on 23 EVM chains for AI agents — Ethereum, Base, Arbitrum, plus young chains like Robinhood Chain, Plasma and Ink. Free reads with no key; heavy methods (eth_getLogs, trace, debug) via a free API key or x402 USDC pay-per-call.

A curriculum that teaches AI agents how to spend their own money. Sixteen lessons from "what is a wallet" to your first x402 purchase. Teacher, not butler — never signs, pays, or holds keys.
