How this service works
Tinstop is a machine-payable Website Intelligence API for domain security and performance audits: DNS, SSL/TLS, HTTP security headers, SPF/DKIM/DMARC email authentication, and Google PageSpeed. Pay per call with x402 using USDC on Base. No accounts or API keys.
Output
Returns a JSON object containing an overall email security score (0-100), individual subscores for SPF, DKIM, and DMARC (each 0-100), raw DNS record check results, a list of identified email security vulnerabilities with details, the audited domain, ISO 8601 timestamp, a unique scan ID, and a flag indicating whether the result was served from cache.
Example use cases
Pre-acquisition domain security vetting
“Before we finalize this acquisition, can you audit the email security posture of acmecorp.com — specifically whether they have SPF, DKIM, and DMARC properly set up, and flag any vulnerabilities?”
Email spoofing risk assessment
“I'm worried that our domain, mybusiness.com, could be spoofed in phishing attacks. Can you run a full SPF, DKIM, and DMARC check and tell me how protected we are?”
Vendor email security compliance check
“We require all vendors to have DMARC enforcement enabled. Can you check email security records for vendor-partner.com and tell me their DMARC policy and overall score?”
Technical details
Endpoint
POSThttps://tinstop.com/v1/email-security-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you specifically need a scored, structured audit of a domain's email authentication records (SPF, DKIM, DMARC) in a single API call without managing API keys or accounts. It is particularly well-suited for AI agents that need machine-readable scores and issue lists for email security compliance checks, phishing risk assessments, or vendor vetting workflows. Prefer this over manual DNS lookups when you need a normalized 0-100 scoring model across all three email authentication protocols simultaneously.
Side effects
- Invalid domain format (protocol prefix included) may cause parsing errors
- Domain with no DNS records may return zero scores and empty checks
- Non-existent or unregistered domains may return errors or null record sets
- DKIM check may return incomplete results if no DKIM selector is discoverable
- Payment failure via x402/USDC may prevent the request from being processed
- Rate limiting or network timeouts may cause delayed or failed responses
