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

Do you train on my data?

Accepted Answer

No. We never use your prompts or responses to train any model, and we don't store them. Each request is passed to the model to get your answer, then it's gone. We only keep usage details like token counts, times and error codes, which we need for billing and to keep the service running.

Question 6

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 7

What happens when my balance runs out?

Accepted Answer

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

Question 8

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 9

What should I include in a ticket?

Accepted Answer

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