Strale Email Reputation Score

Choose this endpoint when you need a scored, auditable reputation assessment of an email address — particularly in fraud prevention, identity verification, or lead qualification workflows where a cryptographic audit trail is required. It is especially useful in regulated or compliance-sensitive pipelines where you need to demonstrate due diligence. Prefer it over simple email syntax validators when you need behavioral and domain-level risk signals, not just format checks.

• Missing email query parameter returns validation error
• Malformed or non-RFC-compliant email address may return an error or zero-score result
• Unknown or newly registered email domain may yield low-confidence score
• Rate limiting or payment failure via x402 may block the request
• Transient upstream provider outage may cause delayed or empty response
