opencode-requesty-plugin

An opencode TUI plugin that shows your Requesty.ai budget, current monthly spend, and per-model cost distribution right in the session prompt, in the session sidebar, plus a detail dialog via the /requesty slash command.

Features

The plugin surfaces your Requesty.ai budget and usage in three places, each optimized for the space it occupies: a compact sidebar, a full detail dialog, and a minimal prompt-area readout.

Sidebar widget

The sidebar gives a quick, at-a-glance view of your current month's Requesty usage:

• Monthly spend and monthly limit, pulled from GET /v1/manage/apikey/self
• A color-coded progress bar that turns yellow/red at configurable thresholds
• Projected month-end spend at the current run rate (~$X EOM), with a pace marker: ↑ over pace, → on pace, ↓ under pace
• Daily spend trend: today · 7-day average · 30-day average
• API key name in the header, linking to the Requesty analytics dashboard filtered by that key
• Top models for the current month (up to sidebar.maxModels), each with spend, total tokens, and input (↑) / output (↓) breakdown

You can disable the sidebar entirely with "sidebar": { "enabled": false }.

Detail dialog

Open the dialog with /requesty or by picking Requesty: show usage from the command palette for the full breakdown:

• KPI row: spent, limit, remaining, End of Month projection with a colored pace arrow, and last month's spend with a colored trend chevron
• Budget Overview card: wide progress bar, budget-health badge, days-to-exhaustion estimate based on your 7-day average, and today/7d/30d averages
• Model Breakdown (Current Month) card: per-model table with spend, share of total spend, tokens, request count, and output/input ratio

Prompt indicator

A compact readout on the right side of the session prompt shows:

• Today's spend
• Spend vs. limit with percentage and API key name, colored by the same thresholds as the sidebar
• Optional month-end projection (~$X EOM ↑) when prompt.monthlyProjection is enabled

Disable the readout with "prompt": { "budgetIndicator": false }.

Data comes from the Requesty Management API (apikey/self + apikey/self/usage grouped by model_used, current calendar month).

Installation

Add the plugin to your tui.json (project root or ~/.config/opencode/tui.json):

{
  $schema": "https://opencode.ai/tui.json",
  "plugin": ["@christiangalsterer/opencode-requesty-plugin"]
}

Or with options:

{
  $schema": "https://opencode.ai/tui.json",
  "plugin": [
    [
      "@christiangalsterer/opencode-requesty-plugin",
      {
        "refreshIntervalMs": 300000,
        "sidebar": {
          "enabled": true,
          "maxModels": 5
        },
        "warningThreshold": 0.6,
        "errorThreshold": 0.85
      }
    ]
  ]
}

Restart opencode after changing the config — plugins are loaded at startup.

Local development install

Point at a local checkout instead:

{
  "plugin": ["file:///absolute/path/to/opencode-requesty-plugin/dist/tui.tsx"]
}

Run bun install && bun run build in the checkout first.

API key detection

The plugin reads your Requesty API key from the opencode provider config: provider.requesty.options.apiKey in opencode.json, including {env:VAR} interpolation.

{
  "provider": {
    "requesty": {
      "options": { "apiKey": "sk-..." }
    }
  }
}

Or via an environment variable:

{
  "provider": {
    "requesty": {
      "options": { "apiKey": "{env:REQUESTY_API_KEY}" }
    }
  }
}

If no key is found, the widget shows a short setup hint instead of failing.

Configuration

Configuration options

Option	Type	Default	Description
refreshIntervalMs	number	300000 (5 min)	Periodic refresh interval (safety net)
warningThreshold	number	0.7 (70%)	Budget usage ratio at which the bar turns yellow (accepts 0–1 or 0–100)
errorThreshold	number	0.9 (90%)	Budget usage ratio at which the bar turns red (accepts 0–1 or 0–100)
sidebar.enabled	boolean	true	Show the sidebar widget
sidebar.maxModels	number	5	Number of models shown in the compact sidebar list
prompt.enabled	boolean	true	Show the prompt widget
prompt.budgetIndicator	boolean	true	Show spend/limit readout on the right side of the session prompt
prompt.dailySpend	boolean	true	Show today's spend to the left of the budget indicator in the session prompt
prompt.monthlyProjection	boolean	true	Show a month-end projection (~$X EOM ↑) in the session prompt, red when the estimated spend exceeds the budget

warningThreshold must be lower than errorThreshold; if the ordering is invalid, both fall back to the defaults (70%/90%). Values above 1 are treated as percents, e.g. 80 means 80%.

Complete configuration example

{
  "$schema": "https://opencode.ai/tui.json",
  "plugin": [
    [
      "@christiangalsterer/opencode-requesty-plugin",
      {
        "refreshIntervalMs": 300000,
        "sidebar": {
          "enabled": true,
          "maxModels": 5
        },
        "warningThreshold": 0.7,
        "errorThreshold": 0.9,
        "prompt": {
          "enabled": true,
          "budgetIndicator": true,
          "dailySpend": true,
          "monthlyProjection": true
        }
      }
    ]
  ]
}

Data is refreshed on startup, on a periodic interval, when a new session is created, and when messages are updated.

Requirements

• opencode ≥ 1.18 (TUI plugin API with slots)
• A Requesty API key — create one at app.requesty.ai/api-keys

Development

bun install
bun run typecheck   # tsc --noEmit over src/ and test/
bun test            # unit tests via bun:test
bun run build       # copy src/* → dist/

The project is fully typed TypeScript (strict mode). Sources live in src/ (.ts/.tsx), tests in test/. The opencode host transforms TSX at load time via @opentui/solid/preload (Bun); no bundler is used.
