Core API
Rate limits
How throughput and spend are bounded during the beta.
Spend caps#
The main guardrail is the per-key monthly USD spend cap you set in Settings → API keys. When a key reaches its cap, calls return 402 spend cap reached until you raise it or the billing cycle resets. Leave the cap empty for no limit.
Throughput#
Concurrency is managed per key during the beta to keep the shared engine pool healthy. If you need higher throughput for a launch, tell us in your access request and we'll provision it.
These limits loosen as the beta matures into self-serve. Building something high-volume? Tell us in your request →
