"description": "Nine chain onchain intelligence with a verifiable track record. Free tools serve the proof stream. Paid tools cost 1 to 25 cents per call in stablecoins over Binance b402 on BNB Smart Chain (USDT, USDC, USD1, U) or x402 on Base (USDC), or run on an API key an agent can buy in-band with the buy_key tool. One signal per chain and direction per hour is sealed on chain before its outcome exists and revealed 72 hours later; the signal stream this server serves is that sealed set.",
