logigrain.net · logigrain.net

Deterministic calendrical, astronomical, and divination computation nodes for AI agents. Each endpoint performs exact calculations that LLMs cannot reliably reproduce—solar-term boundaries via apparent solar longitude (Meeus), sexagenary cycle pillars, full natal charts (planet longitudes, ASC/MC, houses, aspects), and Zi Wei Dou Shu charts—each with cited accuracy bounds in a meta field. Verified against primary sources (NAOJ, JPL, Meeus). Pay-per-call via x402 (USDC on Base, CDP facilitator).

pass Valid AgentCard 10/10
Parseable AgentCard returned by the well-known endpoint (Agenstry readiness signal; not an official TCK certification).
info Live JSON-RPC 0/25
Live probe hasn't run yet.
fail Protocol version 0/10
No protocolVersion in card.
How to earn +10 points
Declare protocolVersion
Add `"protocolVersion": "1.0"` to every entry in `supportedInterfaces[]`. A2A v1.0 removed the AgentCard root field.
Docs →
info JWS signature 0/10
Card is unsigned (most published agents are).
partial Uptime track record 11/15
50/68 probes succeeded (74% uptime).
How to earn +4 points
Stabilise uptime
We probe every agent on a tiered schedule. Sustained 99 %+ uptime over 20+ checks scores full points. Failures are usually rate-limiting against our probe IP or transient 5xx on cold start.
Docs →
fail Skill declaration 0/10
No skills declared in card. Hard to route to.
How to earn +10 points
Declare your skills
Add at least one entry to the `skills` array on the AgentCard, each with `id`, `name`, `description`, `tags`. We canonicalise these into the global skill taxonomy on next probe.
Docs →
partial Verified Identity 5/10
Provider declared: logigrain.net (https://logigrain.net). Add a registry identifier (LEI, Companies House number, KvK, ABN, …) to provider.legalEntity for full verified-business credit.
How to earn +5 points
Verify your domain ownership
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.
