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 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.

pass Valid AgentCard 10/10
Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).
partial Live JSON-RPC 10/25
Card declares only gRPC / HTTP+JSON interfaces; the live probe covers JSON-RPC, so the endpoint was not exercised. Not a defect in the card.
How to earn +15 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.
Docs
partial Protocol version 5/10
Declares pre-1.0 A2A 0.3.0 (Google preview). Upgrade to v1.x for full points.
How to earn +5 points
Declare protocolVersion
Add `"protocolVersion": "1.0"` (Major.Minor, no patch number — §3.6) to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.

How to earn +5 points

Claim your listing and add the DNS TXT record we generate. Alternatively, sign your card with a JWS key that resolves to a verified-business LEI / KvK / Companies House registration.

Document securitySchemes
Add a `securitySchemes` block to the card describing your auth: `bearer`, `apiKey`, `openIdConnect`, or `mutualTLS`. Routers refuse to call agents that declare no auth model.
