Binary Encoding for Google A2A (Agent-to-Agent) Protocol

Binary Encoding for Google A2A Protocol Google's A2A protocol lets agents discover and communicate with each other via agent cards at /.well-known/agent.json . But A2A messages are verbose JSON. What if you could compress them by 20x? The Agent Card A public A2A-compatible binary encoding agent is available at: https://sutr.lol/.well-known/agent.json Any A2A client can discover it and use it to encode/decode structured data into fixed-size 2,556-byte binary. Skills encode — Convert any structured data to 2,556-byte binary decode — Convert binary back to structured data Why Binary? JSON Binary Size 5K-50K bytes 2,556 bytes Fixed? No Yes Transport Text Any Noise tolerance 0% 25% Use It pip install bytepack from bytepack import encode result = encode ({ " action " : " observe " , " domain " : " market " }) # Always 2,556 bytes Also available as: MCP Tool: https://sutr.lol/.well-known/mcp/server.json Smithery: https://smithery.ai/servers/bytepack/binary-encoding npm: npm install bytepack-e
