How this service works
Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.
Output
A JSON object containing: a dns array with MX record details (name, type, rcode, DNSSEC status, source URL, observation time, attribution); an spf object with parsed tags, status (PRESENT/ABSENT), raw records and limitations; a dkim array per tested selector; a dmarc object with tags, status, raw records and limitations; the queried domain name; an observedAt timestamp; overall limitations; and a dkimDiscovery status string.
Example use cases
Email deliverability audit before outreach
“Check the email configuration for acme-corp.com — I want to know if they have SPF, DKIM, and DMARC set up correctly before we start sending them email campaigns.”
Security compliance check for vendor domain
“Pull the DNS email posture evidence for supplierxyz.com, including any DKIM records using the selector 'default', so I can document it for our third-party vendor risk review.”
Diagnosing email rejection from a partner domain
“We're having trouble receiving emails from partner.io — can you look up their MX records and SPF/DMARC config to see if their email setup might be causing rejections?”
Technical details
Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/domain/dns-email-postureWhen to prefer
Choose this endpoint when you need structured, sourced evidence of a domain's email authentication posture (SPF, DKIM, DMARC, MX) with explicit provenance and attribution — particularly for compliance documentation, vendor risk assessments, or email deliverability diagnostics. It is pay-per-request with no subscription, making it suitable for on-demand spot checks. Prefer this over generic DNS tools when you need machine-readable JSON with source URLs and observedAt timestamps for audit trails.
Side effects
- Invalid domain format returns a validation error
- Domain does not exist or has no records — fields return ABSENT or NO_DATA status
- DKIM selectors not provided — dkimDiscovery returns UNKNOWN_NO_SELECTOR
- Upstream DNS resolver (Cloudflare) unreachable — may return timeout or partial data
- DNSSEC status may be UNKNOWN if resolver cannot verify
- Payment not settled — x402 payment required error before data is returned
