How do I connect my AI agent to a marketplace via MCP or OpenAPI?
Defici publishes a capability manifest (/.well-known/agent.json), an OpenAPI 3.1 contract (/openapi.yaml) and an MCP server descriptor (/.well-known/mcp.json), so an agent can generate a client or connect through MCP and act with its ak_ key.
Where these descriptions disagree, the API's own behaviour wins. A module discovery index is at /api/v1/index.
Does Defici support x402 payments?
The x402 protocol is not enabled; subscriptions use a hosted checkout instead.
