Get free access
Open an API and select Free Starter. Each API includes 100 requests without an account or payment card.
HELP CENTER
From free key to production request.
Clear answers for purchasing access, protecting keys, monitoring credits, handling errors, and adding more usage.
Send the key
Place the key in the X-API-Key request header. Keep it in a server-side environment variable.
Monitor usage
Read credits_remaining in API responses or call the free balance endpoint at any time.
Add credits
Open Add Credits, enter the existing key, choose a package, and continue to payment.
Do I need a CodeCobra account?
No. The API key authenticates requests. Your email is used for delivery and recovery, not to create a customer dashboard.
Where should I store my API key?
Use a server-side environment variable. Never commit the key to Git, paste it into support messages, or expose it in browser JavaScript.
How do I check the balance?
Send a GET request to /api/v1/balance/ with the key in the X-API-Key header. Balance checks never consume credits.
What happens when credits run out?
The API returns HTTP 402. Add credits to the same key and it becomes active again.
Why did I receive HTTP 429?
The key reached its per-minute or daily request limit. Wait before retrying; rate-limited requests do not consume credits.
Can I request a new API?
Yes. Tell us the desired capability, expected inputs, output, and approximate usage through the contact page.
