For a broken page or an API error, include the page or endpoint, what you expected, what happened, and the approximate time. An API request ID helps identify the response without sending payment details.

For a fee-tool question, include the transaction size you entered and the displayed rate or error. Do not send wallet private keys, seed phrases, signed payment authorizations, passwords, or API credentials.

For a privacy question or data request, use the same email address. The privacy policy describes the information this service processes and the limits of deleting public blockchain records.

See About for the current service, Developers for integration instructions, and Status for the payment configuration.
