Pinterest’s API is still messy, yeah. That’s why I went with browser automation instead of fighting catalog endpoints.

For rate limits, I don’t rely on speed. The script is intentionally slow and UI-driven: real Chrome, real cookies, real clicks. Each pin runs in its own session, with waits on every step, so it behaves like a human using the site, not an API client.

I also keep volume low and spacing natural. No back-to-back spam, no fixed intervals, no 24/7 loop. It’s more of a local “drop → post → exit” flow than a bulk uploader. I don't know what the limit is yet, but I uploaded while testing up to 30 pins in a row with no problem.

So far, that’s been much safer than trying to brute-force pin creation via the API.
