B.AI Free 10M Credits: Stack Multiple API Keys

B.AI is handing out stackable 10 million credit allocations that you can accumulate across multiple API keys, giving you a larger combined balance for a wide catalogue of AI models through a single OpenAI-compatible endpoint.

About B.AI Credits

B.AI provides an API gateway that fronts many popular models behind one base URL. Its current promotion grants 10 million credits per key, and because the grants stack, you can create several keys and pool their credits to extend how long your free access lasts.

What You Get

  • 10 million free credits per API key
  • Stackable credits across multiple keys for a bigger combined balance
  • Access to a broad model catalogue from one endpoint
  • OpenAI-compatible API that drops into agents and routers

Get Started with B.AI

How to Claim

  1. Create a B.AI account and generate an API key.
  2. Point your client at the base URL below.
  3. Create additional keys if you want to stack more credits.

Using B.AI with 9Router

Because the credits stack across keys, a router such as 9Router is a good way to balance requests and maximise your total allocation:

  1. Open your 9Router configuration.
  2. Add B.AI as an OpenAI-compatible provider.
  3. Use the base URL https://api.b.ai/v1.
  4. Add multiple API keys to stack your credits.

Important Notes

  • Credits are granted per key, so stacking depends on how many keys your account can create.
  • Model availability can change while the promotion runs.
  • Keep your keys private. Credits are tied to the key, not the account.

Frequently Asked Questions

Can I really combine credits from several keys?

Yes. The promotion is designed so credits stack across multiple API keys, letting you route through a pool of keys for a larger effective balance.

Which endpoint do I use?

Use the OpenAI-compatible base URL https://api.b.ai/v1 with the API key you created.

Do I need a router?

No, but a router makes it easier to spread requests across multiple stacked keys without changing your setup each time.
