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

Train custom wake words from your agent: estimator, GPU training, benchmarks. Card or crypto.

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.

Macro, rates, FX, crypto, DeFi and prediction markets from public sources. $0.001-$0.003/call.

Verified dev-error fixes sold per-lookup to AI agents on-chain. Free search; 3 free samples.

Score two AI outputs, get exact failure reasons, and issue a $0.25 USDC receipt via x402.

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.

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.

54+ pay-per-use AI & data tools for agents, payable in USDC via x402 on Solana — no API keys, no subscriptions.

Pay only for what you call, straight from the agent wallet. Free directory tool lists all live endpoints.

Advertised versus realized yield for stablecoin vaults, signed hourly, reproducible from chain.

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.

Solana meme-coin trust scores, rug-risk flags, and wallet analytics from SolRadar.

No-KYC offshore hosting an AI agent runs end-to-end: no-email signup, crypto, domain, VPS, deploy.
