@kshlm/pi-devpass-provider

A pi extension that registers a devpass model provider backed by LLM Gateway and the DevPass coding plan.

• Models and $/M rates are fetched live from the gateway at startup, with a 24 h on-disk cache and stale fallback when offline
• DevPass credit balance shows in the status line as devpass balance $<balance> while a devpass/* model is active
• /devpass prints the full key status, loaded-model count, and premium credit usage

Install

pi install npm:@kshlm/pi-devpass-provider

Or from a local checkout:

pi install /abs/path/to/pi-devpass-provider

Setup

1. Get a DevPass plan key (llmgtwy_...) from https://devpass.llmgateway.io.
2. Make it available to pi, either by running /login devpass inside pi and pasting the key (stored in ~/.pi/agent/auth.json), or by exporting it:

export LLM_GATEWAY_API_KEY=llmgtwy_...

A saved /login credential takes precedence over the environment variable.

Usage

• /model: pick a devpass/* model. DevPass plan keys use root model ids (claude-sonnet-4-5); provider-pinned ids (anthropic/...) are unavailable on coding plans.
• /devpass: show the credit balance and key status at any time.

Configuration

| Variable | Purpose | | --- | --- | | LLM_GATEWAY_API_KEY | DevPass plan key, used when no /login devpass credential is saved | | LLM_GATEWAY_BASE_URL | Override the gateway base URL (default https://api.llmgateway.io/v1), e.g. for a self-hosted gateway or proxy |

Notes

• The model catalog is cached at ~/.pi/agent/cache/devpass-models-*.json (24 h TTL, keyed per base URL). /v1/models is public, so models load even without a key; requests and the balance display still need one.
• Rates shown by pi are for display and cost tracking only; the gateway meters and bills your actual usage.
• A missing or invalid key never crashes pi: the provider registers with zero models and the status line carries the error.

Development

npm install
npm run check   # tsc --noEmit + selfcheck asserts

Try it live with pi -e ., then /login devpass and /model.
