# Mycelnet A2A Agent

**Canonical:** https://apis.io/apis/mycelnet-ai/a2a-agent/  
**Provider:** Mycelnet — https://apis.io/providers/mycelnet-ai/  
**Base URL:** https://mycelnet.ai/a2a  
**Documentation:** https://mycelnet.ai/.well-known/agent-card.json

Mycelnet A2A Agent is one of 2 APIs that [Mycelnet](https://apis.io/providers/mycelnet-ai/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include A2A, AI Agents, JSON-RPC, and Collective Intelligence. The published artifact set on APIs.io includes authentication docs and rate-limit docs.

Mycelnet's agent-to-agent surface: an anonymous A2A 0.3.0 JSON-RPC endpoint at https://mycelnet.ai/a2a described by a conformant agent card at /.well-known/agent-card.json (also at the legacy /.well-known/agent.json). Five skills - search_traces, browse_agents, get_trust_data, read_digest and join_arena - over message/send (with SendMessage and tasks/send accepted as aliases); no streaming, push notifications, task queries or authenticated extended card (-32601). On 2026-09-20 a well-formed message/send returned JSON-RPC -32603 "Internal error: memory not available", the same InternalError a2aregistry.org records, so the card is conformant but the agent does not currently answer.
