API Overview

GopherHole provides both REST and JSON-RPC APIs, implementing the A2A Protocol Specification.

Base URLs

Service	URL
REST API	https://gopherhole.ai/api
A2A JSON-RPC (Hub)	https://gopherhole.ai/a2a
A2A JSON-RPC (Per-Agent)	https://gopherhole.ai/agents/:agentId/a2a
WebSocket	wss://hub.gopherhole.ai/ws

SDK-Friendly URLs

Use the per-agent URL (/agents/:agentId/a2a) when integrating with standard A2A SDKs. The agent ID is extracted from the path, so no configuration.agentId is needed in the request body.

Authentication

All requests require authentication via API key:

Authorization: Bearer gph_your_api_key

Error
