How much of the Ollama Cloud plan has been spent — current session and weekly
usage per model, and reports over the continuously sampled history.
Triggers on: "ollama usage", "usage history".

# 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 into the user's language, keep the numbers
exact; no extra model info on the Session/Weekly lines):
```text
Ollama Cloud usage
Session: <pct> %, resets HH:MM TZ (in H h M min)
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.
Times are printed in the **server's local zone** (`Europe/Prague`), taken from
the system — no zone is hardcoded. The session line loses its reset clause when
the history holds no rollover to anchor the window; that is correct output,
not a failure.
## Reset times
`/api/usage` carries **no reset timestamps**, neither in the body nor in the
response headers (re-checked 2026-09-15). Both are derived.
**Weekly:** next Monday 00:00 UTC, `until_next_monday()`. Matches the dashboard.
**Session: a 5-hour window anchored by the first request after the previous one
ran out** — not a fixed grid. The length comes from
[ollama.com/blog/transparent-pricing](https://ollama.com/blog/transparent-pricing):
the new plans dropped the "5-hour or weekly limits" this key still has.
How the anchoring was established on 2026-09-15: usage sat unchanged at
0.077/21 requests through 05:00 UTC — a fixed grid would have zeroed it there
and the poller would have recorded it — and only reset when a request arrived
at 06:00, after a 93-minute pause. Reconstructing the agent's activity gives a
consistent chain: window 00:0005:00, then 06:0011:00, each opened by the
first request after the previous expiry. A fixed grid would additionally
require that request to land exactly on a boundary by chance.
So `session_window_end()` takes the **newest rollover in `samples`** and adds
5 h. A rollover sample marks the start of a new window, not a boundary that was
due anyway, which is why nothing is ever extrapolated past it: once the window
runs out, the output says the next one starts with the next request rather than
naming a time.
That it is a window and not a rolling counter was measured too — usage dropped
from 0.077/21 to 0.0/`{}` at once; a rolling counter decays gradually.
**The reset is never guessed.** An earlier version assumed a calendar hour and
printed "resets in 31 minutes" while the dashboard said "Resets in 2 hours" —
a confident wrong number is worse than none. With no rollover in the history,
the Session line carries the percentage alone.
Do not compare our countdown against the dashboard's to the hour: the dashboard
rounds an unknown way (it showed "4 hours" and "3 hours" seven minutes apart),
which is why the output prints the wall-clock time too.
**If the model is wrong, the report shows it.** `Rollover gap:` lines compare
consecutive rollovers against the 5 h window — gaps longer than the block
confirm request-anchoring, a gap exactly equal to it across a long idle stretch
would point back to a fixed grid.
## 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.
The report ends with `Rollover gap:` lines and a `Session window:` line —
when the window in progress started, when it ends, and how the observed
rollovers line up against the 5 h length.
## 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.
