How to try an AI API for free with promo credit

A valid Void API promo code adds a specified amount to your account balance. Use that credit to test requests to models. The amount depends on the code, and free testing is limited by the credited balance and the offer conditions.

A free AI API key is not unlimited free inference

An API key authenticates a request to an AI model. Creating a key does not make model usage free. Void API charges requests to your balance according to the selected model rates.

Promo credit lets you test the API using a bonus balance. It can help with a first request, client setup, or small workload comparisons. The bonus does not turn every model into a free model or provide an unlimited API plan.

Check model pricing before testing

How to redeem a promo code

Register or sign in, open balance funding, and choose the Promo code option. Enter the code you received and confirm redemption. A successful redemption shows the amount credited and the updated balance.

The code must exist and remain active. It can have an expiration date or a total redemption limit. Revoked, expired, or exhausted codes cannot be redeemed, and the same account cannot redeem the same code twice.

This guide does not publish a universal code or a fixed bonus amount. If you do not have a code, ask Void API support about current offers. A bonus is not guaranteed for every registered user.

Get your API key and send a first request

After redeeming credit, create an API key in your account. Select an available model and use its exact ID in the request. The documentation contains the base URL and curl examples, while the connection section covers OpenCode, Codex CLI, and other clients.

Start with a short prompt and response. Long documents, conversation history, and automated agent actions consume more tokens. Review the charge in your account before sending a series of requests.

How many requests can trial credit cover?

There is no universal request allowance. It depends on the promo amount, selected model, and input and output lengths. Compare token rates to estimate which tests fit your trial budget. One agent task can contain several model calls.

When your available balance is used up, continuing requires a top-up or another valid code where its terms allow redemption. Testing and paid usage use the same API key, so adding funds does not require changing your integration.

Frequently asked questions

Can I get an AI API key for free?

Create a key in your account to authenticate requests. Paid models require a balance; a valid promo code can provide credit for testing.

How much free API credit does a promo code provide?

Each code has its own credit amount. There is no fixed bonus for every user; a successful redemption shows the amount credited and your new balance.

Why does my promo code not work?

It may be incorrect, revoked, expired, fully redeemed, or already used by your account. Check the code text and the conditions of the offer.
