That's what was in my OP, I used the API approach, but the rate limits were insanely low (seemingly?) the agent died after 3 steps in a single question.

when was that @sergiotapia? last week we just upped the base rate limit for new API accounts

This was September 11th, 2025.

    38.887K input tokens
That was my usage, and I got rate limited. Thank you for your tips!
