How this service works
Valuable data. Quality leads. Paid per call in USDC on Base via x402. Not charged if the fetch fails or nothing matches. Prices per call (USDC): /v1/jp-invoice-check $0.002; /v1/sec-13f $0.003; /v1/sec-8k $0.003; /v1/sanctions-screen $0.0025; /v1/tenders $0.011; /v1/uk-tenders $0.003; /v1/fr-tenders $0.006; /v1/au-contracts $0.0035; /v1/wallet-risk $0.0025; /v1/kyb $0.0029; /v1/read $0.0019; /v1/crawl $0.0045; /v1/jobs $0.01; /v1/domain-profile $0.003.
Output
A JSON object with a `data` field containing: DNS section (A, MX, NS, CAA, AAAA records, TXT count, DNSSEC validation status), TLS section (certificate issuer, expiry, days remaining, domain coverage), web section (HTTPS status, HTTP status code, page title, HSTS, redirects), email security section (SPF, DKIM selectors, DMARC policy and enforcement), detected provider stacks (DNS, mail, hosting/CDN, verified services), and tech stack entries with evidence. Also includes `rows` count and `fetchedAt` timestamp.
Example use cases
Email security audit before outreach
“Before we start cold emailing leads at acme.com, can you pull their domain profile so I can see if they have DMARC enforced and what mail provider they're on?”
Vendor technical due diligence
“We're onboarding a new SaaS vendor at cloudvendor.io — can you get me their domain profile so I can review their TLS certificate expiry, DNSSEC status, and what hosting infrastructure they're running on?”
Competitive tech stack research
“I want to know what hosting, CDN, and tech stack our competitor at shopify.com is using — can you pull their domain profile?”
Technical details
Endpoint
GEThttps://johto-x402-api.johtodata.workers.dev/v1/domain-profile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a consolidated technical snapshot of a domain covering DNS, TLS, email security, and hosting in a single call. It is ideal for due diligence, vendor assessment, competitive intelligence, and email deliverability checks. Prefer it over running separate DNS or WHOIS lookups when you want structured, multi-faceted domain intelligence in one request at low cost ($0.003 USDC per successful call).
Side effects
- Domain not found or unresolvable — returns no rows and is not charged
- Invalid domain format — rejected by schema validation before payment
- TLS check fails due to connectivity — TLS section may be empty or partial
- Domain exists but has no web presence — web section returns empty/null fields
- Rate limiting or upstream DNS resolver errors — transient failures not charged
