Anthropic API Pricing 2025 | MetaCTO
What are Anthropic "thinking tokens"?
Thinking tokens are a new cost for Claude 4.1 models, charged when the model uses external tools or functions you provide. You are billed for the data sent to and received from these tools, which is separate from the standard input/output token costs for generating the final text response.

Anthropic API Pricing 2025 | MetaCTO
How does Anthropic pricing compare to OpenAI/GPT-5?
They are priced very differently, creating a strategic choice. As of September 2025, OpenAI's flagship GPT-5 costs a flat $30 per million input tokens and $60 per million output tokens, but it does not have a separate charge for tool use. Claude 4.1 Sonnet is much cheaper for simple text I/O, but can become more expensive for tool-heavy tasks. GPT-5 is simpler to budget for, while Claude 4.1 can be more cost-effective if your tool usage is efficient.

r/ClaudeAI on Reddit: Confused about Claude API billing - How exactly does it work?
July 11, 2024 -
I'm trying to wrap my head around how Anthropic bills for the Claude API. Their pricing seems straightforward at first glance:
X $ per million input tokens
Y $ per million output tokens
But I'm not quite sure how this translates to actual billing. Does Anthropic:
Add up all input tokens across all API calls separately?
Add up all output tokens across all API calls separately?
Then charge based on these total counts?
Or is there more to it that I'm missing?
Top answer 1 of 2

More or less exactly as you described it. Note though that if you're using a UI, say TypingMind or librechat, a single "chat" sends the entire conversation so the tokens add up significantly over time.

Correct. Each model does have its own cost per token, so it would be the sum of all api calls per model.

tl;dr: I am looking for an API that tells me how much credit I have with Anthropic but cannot find one. And I have some questions.. :)
Hi, all. I hope you are having a great day.
I've been using Anthropic APIs for my side project, which so far has been fun.
For an admin dashboard, I am looking for an API to show how much credit I have left with Anthropic, and to my surprise, I cannot find it in the official documentation.
Upon inspecting network calls when visiting Anthropic Console page, I can see that they already have an internal endpoint, which is https://console.anthropic.com/api/organizations/{org-id}/prepaid/credits ( I haven't tried hitting it from my app, but I image they have CORS enabled ).
I also see a few other existing (internal) endpoints that seem to be useful [0] to make public and also bake into client SDK, such as /invoice_balance*,* /invoices*,* and /current_spend. And the below are my questions
If billing APIs already exist and I missed, I am terribly sorry. Can someone kindly point me to relevant doc(s) please?
Does anyone know if Anthropic plans to release "billing APIs"?
Is there a process to request APIs, and perhaps we can vote candidate APIs as a community?
I searched this community first and failed to find a similar question, so I decided to post.
Thanks everyone!
Warm regards
[0] With billing APIs, a few example use cases I can see are
dynamically change AI model depending on the remaining balance
set alerts based on current usage / remaining balance / invoice
maybe, if an app were to be powered by donation, you could show the current credit when asking for donations?
