Question 1

Is there a subscription or minimum spend?

Accepted Answer

No subscription and no monthly fee. You top up a prepaid balance and pay per token. The smallest top-up is $20.

Question 2

How do I add funds?

Accepted Answer

Open Billing in the dashboard and choose Add funds. Pick an amount and a cryptocurrency, and you'll be taken to the payment page. Your balance is credited once the payment is confirmed on-chain.

Question 3

My payment hasn't shown up yet.

Accepted Answer

Payments are credited after the network confirms them, which can take a while on some chains, and a payment that arrives after the invoice expires is still credited. An underpaid invoice isn't credited automatically: raise a ticket with its ID from the Billing page and we'll sort it out.

Question 4

Which SDKs and tools work with GreenTokens?

Accepted Answer

Anything that speaks the OpenAI or Anthropic API: the official SDKs, Claude Code, Codex CLI, opencode and plain HTTP. Change the base URL and use your GreenTokens key.

Question 5

How is usage billed?

Accepted Answer

On the exact token usage the provider reports, at the prices on our models page. Cached input is billed at the lower cached-input price.

Question 6

What happens when my balance runs out?

Accepted Answer

Requests return HTTP 402 until you top up. Nothing is charged beyond your balance.

Question 7

Can I limit what an API key spends?

Accepted Answer

Yes. On the API Keys page you can set daily and monthly spend limits per key, pause a key, or revoke it instantly.

Question 8

What should I include in a ticket?

Accepted Answer

The request ID from the x-request-id response header (it's also in your Requests log), the model, and what you expected to happen.

Question 9

How do I delete my account?

Accepted Answer

Go to Settings and choose Delete account. We'll delete your account within a few days of the request.
