agent-card-fetch
Agent discovery card fetch: looks for /.well-known/agent.json and /.well-known/agent-card.json (Google A2A Agent Card) plus /llms.txt and /.well-known/ai-plugin.json, and summarises whatever is found: name, description, url, version, capabilities (streaming, push), skills (id, name, description, tags), auth schemes, input/output modes, and provider. Lets agents learn what another agent offers. $0.01 per domain.
