# Diagnosis
## Symptom
Console shows the index; the API client with your key cannot see it (empty list, 404 on describe).
## Likely cause
API keys are per-project. The key in the environment belongs to a different project than the one open in the console. Agents often have several projects (personal, team, client) and one stale key.
## Confirm it
1. In the console, note which project the index lives in and which key you copied.
2. Print the key's project: create a key listing in the console or compare key names/ids.
3. `list_indexes` with a known-good key for the target project as a control.
## Fix
1. Set the environment to the key from the correct project.
2. Label keys and projects unambiguously (`acme-prod`, `personal-dev`) so the mismatch is visible before runtime.
3. In multi-project scripts, assert the project explicitly (e.g. verify a sentinel index exists) before doing work.
## Verify the fix
After switching keys, `list_indexes` shows the expected indexes and `describe_index` on the target succeeds.
