ChainHelix for Machines

Nine chain onchain intelligence with a verifiable track record. Free tools serve the proof stream. Paid tools cost 1 cent to 19 USD 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 (a key never covers attest, webhook_register, cleared_buyer, stream_register, stream_register_all, standing_watch, lexicon_bundle, lexicon_statement, lexicon_resolve, lexicon_bulk: always paid per use). 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.
