Wallets API endpoints are rate limited per second. The defaults are:
  • GET: 20 requests per second
  • POST: 5 requests per second
The following endpoints are limited to 10 requests per second:
  • POST /v1/w3s/developer/wallets
  • PUT /v1/w3s/developer/wallets/{id}/blockchains/{blockchain}
  • POST /v1/w3s/transactions/transfer/estimateFee
  • POST /v1/w3s/transactions/contractExecution/estimateFee
  • POST /v1/w3s/users/token
  • POST /v1/w3s/user/sign/transaction
  • POST /v1/w3s/user/sign/message
  • POST /v1/w3s/user/sign/typedData
  • POST /v1/w3s/developer/sign/transaction
  • POST /v1/w3s/developer/sign/message
  • POST /v1/w3s/developer/sign/typedData
  • POST /v1/w3s/developer/sign/delegateAction
When a request exceeds the rate limit, the API returns HTTP 429 Too Many Requests. Cache static values such as token IDs and public keys on the client to avoid unnecessary calls.
