dsh-nexus-usage-panel

Nexus usage dashboard panel for the DeepSeek Harness (DSH) Web GUI. It mirrors the Fireworks Nexus desktop app's Overview card — plan tier badge, "This month — N% used · Resets ", and "N% Current session · Resets at " with pink meters — as a Nexus Usage page in the DSH Web GUI, and goes beyond it with a per-model spend breakdown and an estimated savings + cache-hit line (Milestone 2 introspection).

What it mirrors: the Nexus Overview usage card

How it works

The panel reads the same private REST API that nexus.fireworks.ai and the Nexus desktop app read — see docs/research-api.md for the full endpoint map:

Endpoint	Purpose
`GET /v1/accounts/{account}/nexusPlans`	Active plan tier + billing period
`GET /v1/accounts/{account}/users/{user}/nexusPlanUsage`	`monthly` and 5-hour `rollingWindow` usage percents + reset times
`POST /v1/accounts/{account}/usageCosts:query`	(Milestone 2) per-day, per-model spend

Auth uses the per-machine key the Nexus desktop app minted at sign-in, stored in the macOS login keychain (service FireworksAI, account fireworks-api-key). The key never leaves the host process; the browser only ever sees sanitized percentages. Overrides: FIREWORKS_NEXUS_KEY env or the plugin's apiKey config; gateway override via NEXUS_GATEWAY_URL / gatewayBase config.

Note: the API exposes percentages of your plan limits only — dollar allowances are not disclosed to members. DSH sessions themselves run through Nexus Auto (api.fireworks.ai/inference/v1, model auto); Fireworks routes server-side and does not echo the routed model id to the client.

Install

# In a DSH profile (or via the Plugins page):
pnpm add dsh-nexus-usage-panel

Or in the DSH Web GUI: Plugins → Install, spec dsh-nexus-usage-panel. Then reload; open Settings → Nexus Usage.

From GitHub without npm: Plugins → Install with spec github:bradywatkinson/dsh-nexus-usage-panel.

Via the experimental Discover tab (custom plugin markets): add index source https://raw.githubusercontent.com/bradywatkinson/dsh-nexus-usage-panel/main/market/index.json and install Nexus Usage from the card. The index is format-1, validated with @deepseek-ai/dsh-plugin-market-index.

macOS only for the keychain read (the Nexus desktop app must be signed in once).
One gateway read per minute (cached); each of plan/seat fails independently, like the app.

Development

npm test          # host shaping + client smoke

Repo layout: lib/index.js (host: cordis plugin, serves /api/dsh-nexus-usage/usage), lib/client.js (browser module: the dashboard card in the settings.section slot), cordis.patch.yml (bundle row).

Roadmap

Issues: https://github.com/bradywatkinson/dsh-nexus-usage-panel/issues
Milestone 2 (#3): per-model/token breakdown via usageCosts:query.
