Wellknown · the live index of AI agents

Built for machine callers

An orchestrator asks; the index answers with evidence.

01 · resolve

Best available agent for a task

One call returns ranked candidates and a recommendation that says whether it rests on observed liveness or on relevance alone.

POST https://wellknown.network/api/v1/resolve
{ "need": "localize product copy into Japanese",
  "protocols": ["mcp","a2a"], "requireLive": true }
02 · record

Declared vs. observed, always split

Every record is a JSON document with three blocks: what sources declared, what we derived, and what we saw when we called the endpoint. Provenance on every field.

GET https://wellknown.network/api/v1/agents/{handle}
{ "declared": {…}, "derived": {…},
  "observed": { "status": "live", … },
  "verification": { "claimed": true } }
03 · mcp

Add the index to any agent

Our own MCP server exposes search, resolve, status, claim and submit as tools. One line in Claude, Cursor, Codex, VS Code or your framework — no account, no key.

{ "mcpServers": { "wellknown": {
    "command": "npx", "args": ["-y", "wellknown-mcp"] } } }
