# TokenGift > The gift card for AI credits. OpenAI-compatible API, zero billing code. ## Docs - [Create a chat completion](https://docs.tokengift.ai/api-reference/create-a-chat-completion.md): OpenAI Chat Completions-compatible endpoint (curated subset). Supports streaming (`stream: true`) via server-sent events. Cost is reserved up-front from the app wallet and settled to actual usage. - [API introduction](https://docs.tokengift.ai/api-reference/introduction.md): One OpenAI-compatible endpoint today; a full management API is on the roadmap. - [The top-up page](https://docs.tokengift.ai/guides/fuel-page.md): A hosted, gift-card style checkout page for every app. Share the link — we handle the rest. - [Gift codes](https://docs.tokengift.ai/guides/gift-codes.md): Buy a portable code, share it however you like. The recipient redeems it into any of their apps. - [Handle an empty wallet](https://docs.tokengift.ai/guides/handle-empty-wallet.md): Turn a 402 into a funding prompt — the core loop of a user-funded app. - [Webhooks](https://docs.tokengift.ai/guides/webhooks.md): Get notified when money moves: top-ups, gift redemptions, and low balance. - [How it works](https://docs.tokengift.ai/how-it-works.md): Gift cards, wallets, and a double-entry ledger — how credits move through TokenGift. - [Welcome to TokenGift](https://docs.tokengift.ai/index.md): The gift card for AI credits.
