# Usage

Shows Ollama Cloud credit usage for the current API key.

## Run

```bash
uv run skills/usage/scripts/ollama_usage.py
```

The script reads `OLLAMA_API_KEY` from the `workspace/.env` file (created by
the user). If it is missing or the key fails (401/403), tell the user —
never scrape the website.

## Output

Format (script prints it, present it to the user as-is — same lines, same
order; translate the labels to Czech, keep the numbers exact; no extra
model info on the Session/Weekly lines):

```
Ollama Cloud usage
Session: <pct> %, resets in X hours
Weekly:  <pct> %, resets in Y days
Models (request count, weekly window):
  <model>: <count>
```

The per-model breakdown lives only in the "Models" section — never inline
on the Session/Weekly lines.

## Reset times — derived, not from the API

`/api/usage` contains **no reset timestamps** (they exist only in the HTML
UI). The script computes them: session = until the next full hour UTC (the
dashboard shows "Resets in 1 hour"), weekly = until the next Monday 00:00
UTC. Rationale: session usage climbed in real time during testing (rolling
window), weekly changes slowly — consistent with hourly/weekly windows.
If the window turns out not to be calendar-based, fix `until_next_*`.

## Continuous sampling

A cron job runs `scripts/ollama_usage_poll.py` every minute and appends to
`db/ollama_usage.sqlite` whenever anything changed (table `samples`; table `meta`
records every poll, so a gap can be told apart from a failed poll).

For a delta report over that data:

```bash
uv run skills/usage/scripts/ollama_usage_report.py [--since ISO] [--until ISO]
```

Default window is the last 24 hours. Per-model **request counts** are the exact
figure there — `limits.*.usage` has a resolution of 0.1 %, so short-interval
percentage deltas are noise.

## Notes

- Endpoint: `GET https://ollama.com/api/usage`, header
  `Authorization: Bearer <key>` (verified 2026-09; issue #15132 is stale).
- `limits.*.usage` is a fraction of the plan limit (× 100 = % as on the
  dashboard).
- `activity.cost` returns $0.00000 on the Pro plan — broken, omitted from
  the output.
- The `~/.ollama/id_ed25519` key does not work — only an API key minted at
  ollama.com/settings/keys.
