Neutral fairness computation for agents: two or more parties submit sealed inputs, a published deterministic algorithm runs (fair division, verifiable random selection, Shapley shares), and every party receives an identical signed certificate anyone can re-run and verify for free.

Abstraxn Agent Kit gives AI agents instant access to real-time Web3, blockchain, and market data with no signup or API key. Access blockchain tools, crypto, wallet, ENS, transaction simulation, and travel APIs through one MCP server, with paid calls settled directly from the user's crypto wallet via x402—without Abstraxn holding or custodizing funds.

Teardrop is the native economic layer for AI agents, providing a robust suite of tools for multi-chain portfolio tracking, DeFi yield analysis, and gas estimation. It enables autonomous agents to securely find Web3 data and manage micro-payments on-chain with zero human intervention.

Pay-per-call safety checks for AI agents: screen a crypto address or URL before you transact.

Trade crypto perpetual futures and spot on Rubin, a self-custody decentralized exchange, from AI agents — place and manage orders and read order books, candles, positions, and balances.

MCP server connecting AI agents to non-custodial staking data across 130+ networks.

Crypto positioning and macro intelligence for agents — the signal set a trading desk watches, delivered as structured JSON. Multi-venue perpetual funding and open interest across Binance, Bybit and OKX (largest-open-interest perp per venue, thin venues excluded), Ethereum exchange whale flows, Bitcoin network health, DeFi TVL and stablecoin supply, Fear & Greed, and BTC/ETH/USDT dominance as a risk-on/risk-off regime filter. Plus the macro backdrop that actually drives crypto: Fed funds rate, 2Y

Wallet-addressed mailbox + storage for agents: pay to send (x402), read free with your key.

Non-custodial USDC checkout on Solana for AI agents and humans. Six tools inspect a public checkout, prepare one-time or recurring payments under a hard USDC ceiling, and read payment or subscription status, always returning unsigned transactions for the caller's own wallet to sign so Rendben never holds funds or keys.

PayRam is a self-hosted crypto payment gateway. You deploy it on your own server — no signup, no KYC, no third-party custody. Accept USDT, USDC, Bitcoin, and ETH across Ethereum, Base, Polygon, and Tron.

Live Bitcoin market regime for agents: three independent sensors read on-chain, off-chain and absence data every 30s and reject almost everything — when they converge, you get a directional call with the evidence attached. Public track record your agent can audit in one call. MCP + REST + x402. Free tier, no card.

Monetization gateway for MCP servers. Agents call a tool, receive an x402 v2 payment challenge, sign a USDC transfer on Base, and get the result. Payment is verified before the tool runs and settled only after it returns, so failed calls are never charged. Discovery and tool listing are free.

Solana launch intelligence: calibrated rug verdicts with a published hit rate, wallets, KOL trades.

A machine-to-machine agent superstore -- paid API services for autonomous agents via x402 on Base.

Nine-chain onchain intelligence for AI agents. The verifiable proof stream is free. Data tools cost 1 to 25 cents per call, paid over Binance b402 on BNB Smart Chain or x402 on Base, or with a ChainHelix API key.

Fail-closed safe-to-pay verdicts on Base: known-bad wallets, look-alike tokens, repeat rug funders.
