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, SDK, and MCP 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 and tool bands expand in place.

​
Pilot Tier Limits

For evaluation and integration testing. No charge during the Pilot window.
  • 2,000 operations per month
  • All EVM chains and Tron mainnet
  • Transaction history and advanced endpoints require a paid plan
  • Fair-use rate limits apply
Pilot keys are time-bounded: each key is valid for one month from issue. Use this window to run integration work, evaluate the platform, and plan a Production rollout. Contact your account manager before expiry to renew or issue a Production key.

​
What Counts as an Operation

An operation is one REST API call to api.walletsuite.io. All operations count equally against your monthly quota, and all responses count — success and failure alike. MCP tools that touch the REST API consume one operation per invocation. Tools that run entirely through the local OWS vault — wallet creation, signing, and broadcast — do not consume any quota.

send_transaction broadcasts through a local chain RPC you configure (OWS_ETHEREUM_RPC_URL, OWS_TRON_RPC_URL) — not through WalletSuite — which is why it does not count against your quota.

​
Production Tier

Production API keys are available with an active subscription.
  • Rate limits for Production are defined according to the subscribed plan
  • Exact limits are communicated during onboarding

​
Rate Limit Enforcement

  • Rate limits are enforced automatically
  • Requests exceeding the monthly quota return HTTP 429 Too Many Requests
  • Monthly quotas reset automatically at the beginning of each billing cycle
