As recorded at collection: HappyCode GPT model credits, 3-day free trial

HappyCode is a relay API service, a third-party service that provides official APIs on your behalf, allowing you to use major models such as GPT and Claude without an overseas account. This trial package is for people whose subscription account is short on credits and need to top up tokens temporarily, or who want to use large models occasionally without maintaining several subscriptions long term. It provides GPT standard group model credits worth up to $25 per day and about $100 in total.

After commenting on the post, join the after-sales support QQ group 367746547. Send a screenshot of your comment and the email address you used to sign up to the group owner or an administrator by private message to receive the trial package. Requests made in the group chat cannot be processed, so you must apply by private message.

The trial lasts 3 days from the time you receive it, and in practice you can use it for about 4 days. Paid top-ups are converted at 1 yuan per $1 in credits, and GPT group pricing is 0.12 times the lowest official rate. When someone you invite tops up, you receive 10% of the top-up amount as a bonus balance, which can be used without restrictions on all models on the site. Once your cumulative spending exceeds 500 yuan, you can request a tax invoice for technical services. Any unused balance can be refunded at any time after deducting a 5% fee.
