Use Index Network through its HTTP CLI, with the included index-network skill.
Install the plugin in your agent, then provision its matching CLI release:
./scripts/install.sh
index login --api-url https://protocol.index.networkFor noninteractive authentication, provide INDEX_SESSION_TOKEN or INDEX_API_KEY in the agent process environment. Set only one. Pass --api-url explicitly; use your API origin without /api (production: https://protocol.index.network). Browser login/logout remain available.
Read the protocol's guidance with index docs --json; every resource has its own command (index intent, index network, index opportunity, index scrape). The skill explains negotiation and personal-agent commands and how to handle refusals.
