I have to use API in a project but not willing to pay for API separetly. I am already paying for max subscription. Is there any workaround?

Update: the solution I needed was already built in Claude code. I used Claude -p from terminal and it gave me what I needed.

Considering that a single full 200k input with 30k output is 1$ which you can do easily like 60-70 times on 5x max per 5 hours.

Hey everyone,

Sorry if this is a basic question, but I’m a bit confused about how Claude’s API works. Specifically:

Is SDK/API usage included in the Pro or Max subscriptions, and does it count toward those limits?

If not, is API usage billed separately (like ChatGPT)?

If it is billed separately, is there a standalone API subscription I can sign up for?

Thanks for any insight!

I just purchased Max subscription to save on my Claude Code API usage (I've been spending around $200 per month). I can clearly see that the context window is smaller. When I started using Claude Code with Max subscription I've hit all the time the error:

Error: File content (33564 tokens) exceeds maximum allowed tokens (25000). Please use offset and limit parameters to read specific portions

of the file, or use the GrepTool to search for specific content.

which I didn't see at all when using API. Because of that I've had pretty bad experience so far. While Claude Code with API is top notch agent assistant, the version with Max subscription has trashed my files, causing linting errors everywhere, because it couldn't load the full file.

I asked Anthropic support for clear information about context size, but so far I am pretty sure that they limited the context window, because it would be too good to have 225 messages per 5 hours for $100 per month.

If you have big projects with big database – it might not be good for you.

So yeah, I've spent those $100 so you don't have to.

Hey r/ClaudeAI (and fellow devs!), Been diving deep into whether Anthropic's Max plans ($100/mo for "5x Pro" & $200/mo for "20x Pro") actually make sense if you're hammering away at the Claude Code terminal tool. Wanted to share my thoughts and a bit of a cost comparison against just using the API directly (for Code, Sonnet, and Opus). TL;DR: If you're a heavy, daily user of Claude Code (and Claude generally), especially if you want that sweet Opus power in Claude Code without the eye-watering Opus API prices, Max plans can be a great deal. For casual or light users, sticking with the API is probably still your best bet. So, How Do Max Plans Even Work with Claude Code? First off, your usage limits on Max plans are shared between your normal Claude chats (web/app) and whatever you do in Claude Code. It all comes from the same bucket.

• Max Plan $100 (they call it "5x Pro"):

  • You get roughly 50-200 prompts in Claude Code every 5 hours.

  • Access to both Sonnet 4 and the mighty Opus 4 within Claude Code. BUT, here's the catch: Opus will automatically flip over to Sonnet once you've used up 20% of your 5-hour limit with Opus.

• Max Plan $200 (the "20x Pro" beast):

  • A hefty 200-800 prompts in Claude Code every 5 hours.

  • Same deal: Sonnet 4 and Opus 4 access. For this tier, Opus switches to Sonnet after you burn through 50% of your 5-hour limit on Opus.

• And don't forget, Opus chews through your limits about 5 times faster than Sonnet does. Quick API Cost Refresher (per 1 million tokens):

• Claude Code (via API - it's Sonnet-based + "thinking tokens"):

  • Input: ~$3 / Output: ~$15 (that output cost includes "thinking tokens," which can make it pricier than you'd think for complex stuff).

• Claude Sonnet 4 API (direct):

  • Input: $3 / Output: $15.

• Claude Opus 4 API (direct - hold onto your wallet!):

  • Input: $15 / Output: $75. When Do Max Plans Actually Become "Worth It" for Claude Code?

• You're a Coding Machine (Daily, Heavy Use): If you're constantly in Claude Code and also using Claude for other tasks (writing, research, brainstorming), that $100 or $200 monthly fee might actually be cheaper than what you'd rack up in API fees.

  • Some reports suggest "moderate" daily Claude Code API use can hit $20-$40. If that's your baseline, the Max $100 plan (which works out to about $3.33/day) starts looking pretty good.

• You Crave Opus in Claude Code (Without Selling a Kidney): Getting Opus access within the Max plans is a massive cost saving compared to paying the direct Opus API rates. Even with the usage caps on Opus within the plan, it's a much more affordable way to tap into its power for those really tricky coding problems.

• You Like Knowing What You'll Pay: Fixed monthly cost. No surprise API bills that make your eyes water. Simple. When Might Sticking to the API Be Smarter?

• Light or Occasional Coder: If you only fire up Claude Code once in a blue moon, a $100/month subscription is probably overkill. Pay-as-you-go API is your friend.

• You Need Unrestricted Opus (and have deep pockets): If your workflow demands tons of continuous Opus through Claude Code, the Opus limits within the Max plans might still feel restrictive, and you might end up needing the pricey Opus API anyway.

• You're an API Cost-Saving Wizard: If you're savvy enough to properly implement and benefit from API features like prompt caching (can save up to 90%) or batch processing (50% off), you might be able to get your API costs lower than a Max plan. Heads-Up on a Few Other Things:

• Shared Limits are Key: Seriously, remember that Claude Code and regular Claude chat dip into the same 5-hour usage pool.

• Auto Model Downgrade: That switch from Opus to Sonnet in Claude Code on Max plans is automatic when you hit those percentage thresholds. It's not unlimited Opus all the time.

• "Thinking Tokens" Can Bite: If you use Claude Code via the API (like if your plan runs out and you opt into API credits), it's billed like Sonnet, but those "thinking tokens" for complex agentic tasks can add up.

• The ~50 Sessions/Month "Guideline": For Max plans, Anthropic mentions a "flexible guideline" of about 50 five-hour sessions a month. They say most people won't hit this (it's like 250 hours!), but if you're an extreme user, it's something to be aware of as they might impose limits. My Takeaway: It really boils down to your specific workflow. If you're a Claude Code power user, especially one who benefits from Opus, the Max plans offer genuine value and can save you money. For everyone else, the API's flexibility and pay-for-what-you-use model is probably still the way to go. Hope this breakdown helps someone out there trying to decide!

Hello, guys im juste wondering, now we have access to claude code in the max plan, do we have the possibilitie to use this quota usage in other tool like crewai or other agents or this max plan usage is limited to claude.ai and claude code only ?

Latest CLaude Code is allowed officially to be used with Claude MAX, no more burning API tokens.

0.2.96

• Claude Code can now also be used with a Claude Max subscription (https://claude.ai/upgrade)

https://github.com/anthropics/claude-code/blob/main/CHANGELOG.md

Seem Anthropic want to push Claude Code as alternative to other tools like Cursor and push their Max subscription. May be one day a merge into Claude Desktop.
