How this service works
The trust layer for AI agents — 250+ independently tested data capabilities across 27 countries. Execute capabilities via REST, MCP, A2A, or x402 micropayments. Every call returns an audit record with cryptographic chain hashing.
Output
Returns an assessment of the domain's email deliverability configuration, including presence and validity of MX records, SPF policy, DKIM records, and DMARC policy, along with an overall deliverability status and a cryptographically hashed audit record for trust verification.
Example use cases
Pre-send email campaign audit
“Before we launch this email campaign, can you check whether our domain marketingco.com has proper SPF, DKIM, and DMARC records set up so our emails won't end up in spam?”
Vendor domain trust screening
“I need to verify that the domain invoice-supplier.com is legitimately configured to send email before I trust their invoices — can you check its email deliverability settings?”
Customer onboarding domain health check
“A new customer wants to use clientdomain.io with our platform — can you check if that domain is properly set up for email delivery, including MX records and DMARC?”
Technical details
Endpoint
GEThttps://api.strale.io/x402/v2/email-deliverability-checkWhen to prefer
Choose this endpoint when you need a multi-signal email deliverability assessment covering MX, SPF, DKIM, and DMARC in a single call with an audit trail. Prefer it over raw DNS lookup tools when compliance, trust verification, or chain-of-custody logging is required, especially in automated agent workflows that need verifiable results.
Side effects
- Invalid or malformed domain name returns a validation error
- Non-existent domain returns DNS lookup failure
- Domain with no MX records returns low deliverability score
- Rate limiting or payment failure returns 402 or 429 error
- Temporary DNS resolution failures may cause transient errors
