ChainHelix for Machines

mcp.chainhelix.io · ChainHelix

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.

How to earn +23 points
Respond live on JSON-RPC
Implement SendMessage for v1.0 (or message/send for v0.x), negotiate A2A-Version, and return a schema-valid JSON-RPC response. Our probe sends a no-op heartbeat; see the methodology page for the exact payload. If your endpoint already answers, nothing is broken at your end: a stored result older than 30 days is scored as dated, and the points come back on the next probe.
