No signup
Run public read and simulation calls immediately.
Sandbox
Test Stackit.ai in the browser before you wire an agent.
Run public reads, simulate a borrow, inspect fee rules, copy curl, copy MCP prompts, and verify that unsafe actions are rejected. No signup is required for the first test.

Sample treasury
Use a preloaded BTC/ETH/USDC position with collateral, debt, LTV, and health score.
Raw JSON
Inspect every response exactly as an agent would receive it.
Copy paths
Copy each test as curl or as an MCP prompt.
Safety rejection
See a typed LTV error with a safe_amount field.
Upgrade path
Create a sandbox key for stateful simulated deposit, convert, borrow, repay, and relay calls.

These tests use public demo data and simulated responses. No signup, wallet, API key, or real funds are required.
Sandbox only. Public tests use mock treasury state. Creating a sandbox key creates simulated state only; it cannot move real funds.

Ready
Curl
curl -s https://www.stackit.ai/api/v1/public/portfolio-state?address=demo | jq
Raw response
Run a test to see JSON output.
Public tests
Public endpoints are read-only or simulation-only. They return deterministic demo data for agents to inspect without credentials.
Sandbox keys
Sandbox keys create simulated treasury state. They cannot touch real wallets, production balances, or live funds.
Live access
Production credentials require human review. Real execution uses wallet signatures or user-approved automation permissions.
