All Benchspan SDKs are thin wrappers around the REST API. If your language or framework isn’t supported by an SDK, you can integrate directly.

Rate limits

Free tier is 50,000 scans / month, forever. Current usage is visible on your dashboard. When you exceed the limit, the API returns 429 Too Many Requests. Need more? Talk to us and we’ll scope a plan based on your agent traffic and latency requirements.

​
Latency

Typical p50 scan latency is under 100 ms for inputs up to ~2,000 tokens. The service is built to run inline in your agent loop, so don’t hedge against Benchspan’s latency in your application.
