Block / AAIF harness. Key via goose configure or four env vars.

Three fields. Copy, don’t type

key sk-… sign in with the key — it drops into the commands

model claude-opus-4.8

terminal

export GOOSE_PROVIDER=openai
export GOOSE_MODEL=claude-opus-4.8
export OPENAI_HOST=https://cheapai.lol
export OPENAI_API_KEY=sk-…
export OPENAI_BASE_PATH=v1/chat/completions
goose session

Do it in order. Don’t skip

Install Goose — CLI or desktop, from the Block site.
In a terminal run: goose configure
Choose Configure Providers, then OpenAI. Not Anthropic — we need the OpenAI protocol.
Host is asked WITHOUT the /v1 tail: enter https://cheapai.lol. Goose appends v1/chat/completions itself.
API Key: your full key. Model: claude-opus-4.8.
Prefer variables? Copy the five lines from the card below. On Windows use $env:NAME="value" instead of export.
Run goose session and type “hi”.

Check

The Goose session replied with text, not 401/404.

If it didn’t start

“401 / unauthorized / invalid api key” — the key was not copied whole. It starts with sk- and has no space at either end.
“model not found” / “named models unavailable” / model in red — the name must match exactly: claude-opus-4.8. Not “Opus 5”, not opus, not claude-3, not gpt-4.
The app shows no models — reopen its settings page: the model list is served from our address and appears once the Base URL and key are right.
“Connection error” / spinner and silence — wrong Base URL. Almost every app wants the address with a /v1 tail.
“/v1/v1” in the error — the app appends /v1 itself. Drop the tail, leave the site address.
It replied, then stopped — you ran out of tokens. The balance is in your dashboard. Topping up on FunPay from the same nick lands on the same key.
