API Error 429 : Help

Hi,

I’m consistently getting HTTP 429 responses from the NVIDIA NIM API.

Error:

HTTP 429
{
“status”: 429,
“title”: “Too Many Requests”
}

Environment:

  • Using the NVIDIA NIM API
  • Model: GLM-5.2 (also interested to know if this is model-specific)
  • Client: Custom AI coding agent / CLI
  • Requests are sequential (not intentionally flooding the API)
  • Automatic retries (3 attempts) all return 429

What I’ve checked:

Questions:

  1. Is there currently a rate limit or quota issue affecting GLM-5.2 or NIM endpoints?
  2. Are there hidden per-minute or concurrent request limits that could trigger a 429 even with available credits?
  3. Is this likely an account-specific issue or are other users experiencing the same behavior?
  4. Is there a way to inspect my current rate limits or remaining quota?

Any guidance would be appreciated. Thanks!
