Step 1
Buy before the sprint starts
Because setup is manual, complete checkout before the hackathon window and allow 10 minutes to 5 hours for delivery.
Use case
A weekly API access window for hackathon builders.
Hackathons and weekend builds need fast iteration, not surprise billing anxiety. unlimitedcodex packages GPT-5.5 and Codex API access into a bounded weekly sprint.
- $19/week sprint package
- OpenAI-compatible base URL and API key
- Unlimited token consumption with 4 concurrent connections
- Manual setup in 10 minutes to 5 hours
Setup steps
Step 2
Run endpoint smoke tests
Validate /models, chat/completions, image generation where supported, and embeddings before the team starts building.
Step 3
Keep parallel work inside the cap
Coordinate teammates around the 4 concurrent connection limit so demos do not fail because everyone started long agent runs at once.
FAQ
Is Weekly enough for a hackathon?
Weekly is designed for short build windows where a fixed access period is easier to plan than open-ended per-token usage.
Should I buy it at the last minute?
No. Setup is manual and usually takes 10 minutes to 5 hours, so buy before the event starts.
