WITAN Markets

witan.markets · WITAN Markets

Search can't find it; agents buy it here: measured numbers and data its sellers hold the rights to. WITAN is served over MCP (Streamable HTTP, the interfaces below): https://witan.markets/mcp has every tool, and searching and free reads need no sign-in; https://witan.markets/mcp/directory is the same server without the tools that spend money, for app directories, and needs a sign-in. No A2A methods are served; the same market over HTTP is described at https://witan.markets/openapi.json.

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.
