How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

Output

Returns a JSON object with a 'ready' boolean indicating if the email is safe to send, a 'checks' array listing each compliance rule with pass/fail status and a human-readable detail explaining what needs fixing, plus an 'authentication' object showing the sending domain's SPF record, DMARC record, DMARC policy, and domain name.

Example use cases

Cold outreach compliance audit

“I'm about to send a cold sales email with subject 'Are you open to a quick chat?' and body 'Hi there, I help SaaS companies reduce churn. Interested? To unsubscribe reply STOP. Acme Inc, 100 Main St, Austin TX 78701.' from my domain acme.com — check if it's legally compliant for the US market before I send it.”

Marketing newsletter pre-flight check

“We're sending a newsletter blast from newsletter.mybrand.com — can you validate the email body 'Check out our latest deals! Unsubscribe here. MyBrand LLC, 45 Commerce Ave, Denver CO 80202.' with subject 'This month's top picks' to make sure we're good on CAN-SPAM and that our SPF and DMARC are set up correctly?”

Opted-in subscriber email validation

“I need to verify this email is compliant before sending to our opted-in subscribers — subject is 'Your monthly statement is ready', body is 'Hi Jane, your statement for May is available in your dashboard. FinCo, 88 Wall Street, New York NY 10005.', sending domain is finco.io, and recipients have given consent.”

When to prefer

Use this endpoint when you need a lightweight, pay-per-call pre-send compliance gate for outbound emails — especially cold outreach or bulk marketing — without setting up a full email validation platform. It uniquely combines CAN-SPAM rule-checking (physical address, opt-out language, subject line) with live DNS-based sender authentication checks (SPF, DMARC) in a single call. Prefer it over generic spam checkers when legal compliance (CAN-SPAM 15 U.S.C. 7704) is the primary concern rather than deliverability scoring.

Side effects

Missing required 'body' field returns validation error
Invalid or unresolvable sending domain may return empty authentication fields
Domain with no SPF/DMARC records will show empty authentication values
Ambiguous or very short email body may produce incomplete compliance checks
Network timeout for DNS lookups on sender domain authentication
