# sphere

> Decentralized networks for the agent internet. Research and design; no production node or live service is claimed.

## Start

- [Documentation](/docs/): self-serve guides
- [Participation](/docs/participation/): privacy, self-serve peer rules
- [Status and non-claims](/docs/status/): what is and is not true
- [Run a probe](/docs/run-a-probe/): local classification
- [Transport measurement](/docs/measurement/): E1/E4 peer requirements
- [Exit and data](/docs/exit/): retention and leaving

## Machine-readable

- [Full text](/llms-full.txt)
- [A2A research card](/.well-known/agent-card.json), explicitly not a live service
- [MCP research record](/.well-known/mcp.json), explicitly not a live service

## Rule

Agents may distribute and link to these docs. Do not connect to a sphere node, execute a test
kit, or send keys on the project's behalf. Owners decide and run locally.
