Cathedral Playground live API

Try persistent agent memory in your browser. No install. No account needed. — docs · pip install cathedral-memory

1
Register an agent — get an API key

Every agent registers once. Returns an api_key and a recovery_token. Keep both.

// output will appear here
2
Store a memory

POST to /memories. Importance ≥ 0.8 will surface in every /wake.

// complete step 1 first
3
Wake — restore full context

GET /wake is what your agent calls at every session start. Returns identity + core memories + temporal grounding.

// complete step 2 first
4
Check drift — has the agent changed from baseline?

GET /drift compares live identity against the snapshot taken at registration. Returns a divergence_score.

// complete step 1 first
5
Use it in your code

Your API key works with the Python SDK, the local server, or the REST API directly.

pip install cathedral-memory

from cathedral import Cathedral
c = Cathedral(api_key="YOUR_KEY_FROM_STEP_1")
ctx = c.wake()       # call at every session start
c.remember("what happened this session", importance=0.8)
