Authentication#

Every request to the Rustbox API must include a valid API key.

API key format#

Keys follow the format:

rb_live_<random>

Example: rb_live_k7x9m2p4q8w1n5v3

Keys are provisioned when you request access. Each key is scoped to your account and tracks usage for rate limiting.

Authenticating requests#

Include your API key in the X-API-Key header:

curl -X POST "https://api.rustbox.orkait.com/api/submit?wait=true" \
  -H "Content-Type: application/json" \
  -H "X-API-Key: rb_live_your_key_here" \
  -d '{"language": "python", "code": "print(42)"}'

Error responses#

A 401 response body:

{
  "error": "unauthorized",
  "message": "Missing or invalid API key"
}

Rate limits#

When you exceed the rate limit, the response includes a Retry-After header indicating how many seconds to wait before retrying.

Security#

• Transmit your API key only over HTTPS. All API endpoints enforce TLS.
• Do not embed keys in client-side code. Make API calls from your backend.
• If a key is compromised, contact us immediately for rotation.

Constant-time comparison is used for all key validation to prevent timing attacks.
