I’m experiencing persistent 429 quota errors when running my Make AI agent, despite:
Having available credits on both OpenAI and Claude (Anthropic)
Successfully switching between different LLM providers
The errors occurring immediately without heavy usage
The agent configuration shows valid API connections, but requests are being rejected with quota limit messages.
Is this a rate limiting issue on Make’s side rather than the LLM provider side?
Any guidance would be appreciated. Thank you!
Welcome to the Make community!
429 You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs: https://platform.openai.com/docs/guides/error-codes/api-errors.
Looks like that error message originates from OpenAI, and has nothing to do with Make.
Can you confirm that you’ve set up the credits/limits correctly in the OpenAI dashboard?
To resolve this issue,
You can buy credits on the OpenAI Developer Dashboard, under Accounts > Billing Overview
Next, go to the Usage Limits link on the Billing Overview page, and edit the Monthly budget to the same as the value above (e.g.: 120), then save your changes.

Hope this helps! If you are still having trouble, please provide more details.

Thanks for the guidance! I’ve now checked my OpenAI account and here’s what I found:
Credit balance: $5.76 available
Monthly budget: $2.95 / $120 (plenty remaining)
API key: Active (last used Nov 12, 2025)
Tier: 2 ($500/month limit)
Despite all these being correct, I’m still getting 429 errors when running my Make AI agent.
Could this be a rate limiting issue rather than a billing issue? Or is there something else I should check?
Any other suggestions would be appreciated!
Have you previously uploaded 100GB worth of files to OpenAI?
