Try Grok 4.7 free via a relay API

Want to try Grok 4.7 without a paid plan? Some free relay stations expose it with signup + daily check-in credit. It's served over an OpenAI-compatible endpoint.

Minimal setup for any OpenAI-style client:

export OPENAI_BASE_URL="https://<station>/v1"
export OPENAI_API_KEY="sk-****your-key****"
# model: grok-4.7

Notes:

• The endpoint ends with /v1 (OpenAI-compatible).
• Use the exact model id from the station's model list.
• Don't hardcode the key — use an env var.

These stations are free and usually carry several model families (Claude, GLM, Grok) behind one key, so you can register a couple and pick per task. Full list with models and tested dates: AI relay station list

The signup links carry my referral param — drop ?aff= if you'd rather not.
