What you can do
Every capability, and which client reaches it.
Choose your surface
HTTP, SDK, CLI, MCP, or the AI agent Skill.
Authentication
API key or x402 — which one you need.
Two APIs
Every write on both APIs follows the same three steps: prepare an unsigned transaction, sign it, send it. Dapp API prepares consume API-key credits; Agentic API prepares are free only in relayed mode and are priced as the first half of client-controlled operations.
Clients
REST API
Plain HTTP. Reaches everything.
SDK
brickken-sdk on npm. Typed TypeScript client for all three APIs.MCP server
Hosted, 62 tools. Drives the full Dapp API from an AI agent with just an API key.
CLI
brickken-cli on npm, for KYC, agentic reads/writes, and RAMS workflows.Skill
Brickken knowledge for AI coding agents.
Environments
Sandbox and production are separate deployments with separate databases. An API key issued for one does not work on the other.
