Rate limits are applied per API key and vary depending on the key tier and subscription plan. The same per-key limit applies to every integration path — direct REST and SDK requests all count against it.
Your key automatically promotes from Pilot to Production when your trial converts — no rotation required. The x-api-key header stays the same; quota expands in place.

​
Pilot Tier Limits

For evaluation and integration testing. No charge during the Pilot window.
  • 2,000 API calls per month
  • EVM chains (Tron and other chains available on paid tiers)
  • Hard-capped — calls beyond the included quota are rejected
  • Fair-use rate limits apply
Pilot keys are time-bounded: each key is valid for 30 days from issue. Use this window to run integration work, evaluate the platform, and plan a Production rollout. The key auto-promotes to Production at the end of the trial; quota and feature scope expand in place.

​
Production Tier

Production API keys are available with an active subscription.
  • Rate limits for Production are defined according to the subscribed plan
  • Paid tiers meter overage at a per-call rate
  • Exact limits and pricing are communicated during onboarding

​
Rate Limit Enforcement

  • Rate limits are enforced automatically
  • Requests exceeding the monthly quota return HTTP 429 Too Many Requests
  • All responses count — success and failure alike
  • Monthly quotas reset automatically at the beginning of each billing cycle
