NAWA enforces per-minute rate limits on each API key to ensure fair usage and platform stability.
Tier table
Free keys are rate-limited to 10 requests/minute and have a hard cap of 100 lifetime requests. Live keys start at the Growth tier (120/min). Enterprise tiers are available on request — contact sales@trynawa.com.
Every API response includes rate limit headers:
On 429 responses, additional headers are included:
Semantic cache and rate limits
Semantic cache hits (X-NAWA-Cache: HIT) do not count toward your rate limits. If you’re classifying similar comments repeatedly, caching effectively increases your throughput.
Handling 429 errors
Use exponential backoff with jitter to retry rate-limited requests:
Do not retry in a tight loop without backoff. This will extend your rate limit window and may result in longer delays.
