YOUR_API_KEY with your key.- 1
Create an API key
Create a key in API keys and name it after the tool, for example “curl”. A dedicated key per tool lets you see its usage separately and give it its own parallel-stream cap. The key is shown once; the snippets below use
YOUR_API_KEYwhere it goes. - 2
Export your key
export NEVERMETERED_API_KEY="YOUR_API_KEY" - 3
List the models you can call
curl https://api.nevermetered.com/v1/models \ -H "Authorization: Bearer $NEVERMETERED_API_KEY" - 4
Send a request
curl https://api.nevermetered.com/v1/chat/completions \ -H "Authorization: Bearer $NEVERMETERED_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "qwen3.8-27b", "messages": [{"role": "user", "content": "Reply with the word ready"}] }' - 5
Verify it works
A JSON response with the model's reply means you're set. The request shows up in Requests within a few seconds, with its input, cached and output tokens.
Tips
- Add
-Nand"stream": trueto see tokens as they are generated. - On the free tier, add

Troubleshooting
404 model_not_found- Use a model id exactly as
GET /v1/modelslists it, for exampleqwen3.8-27b. Plans can restrict which models a key may call. 429 concurrency_limit_exceeded- All your parallel streams are busy and your queue allowance is full. Lower the tool's parallelism (subagents, batch size), or get more streams on your plan.
- Answers stop mid-sentence
- The response hit your plan's output cap of 8,192 tokens (finish reason
lengthormax_tokens). Ask for shorter steps, or upgrade for a higher cap. 403 email_verification_required- Free requests need a verified email. Click the link in your verification email (you can resend it from the dashboard), or upgrade.
429 daily_quota_exceeded- You've used today's free requests; agents send one request per step, so they go quickly. The allowance resets at 00:00 UTC, and paid plans have no daily limit.
503/504 request_queue_timeout- The service stayed busy longer than the queue timeout and nothing was generated. Retry with backoff, and give the tool a generous request timeout.
