How this service works
SPF lookup-count + DMARC check: Recursively expand SPF includes, count DNS lookups against the RFC limit of 10, flag +all/?all, duplicate records and weak DMARC policy. Free tier 10/day; then $0.002 via x402 (HTTP 402 + PAYMENT-REQUIRED) or X-API-Key credits. Not charged on failure. $0.002 USDC per call via x402 on Base. Run by MoneyTools.
Output
A JSON object containing: recursive SPF include expansion with per-include DNS lookup counts, total lookup count vs. the RFC 10 limit, flags for dangerous SPF mechanisms (+all, ?all), duplicate SPF record detection, DMARC record presence and policy strength assessment, plus payment metadata (whether a charge was made, network, amount, transaction hash).
Example use cases
Pre-send email deliverability audit
“Before I start sending marketing emails from acme.com, can you check whether our SPF record stays within the 10 DNS lookup limit and whether our DMARC policy is properly configured?”
Diagnosing email bounce or spoofing issue
“Emails from our domain mailchimp-linked domain newsletter.example.com keep getting rejected or spoofed — can you check the SPF lookup count and flag any DMARC weaknesses?”
Third-party domain security review
“We're onboarding a vendor who will send emails on behalf of our brand — can you audit their domain vendorcorp.io for SPF lookup overflows, +all usage, and weak DMARC policy before we approve them?”
Technical details
Endpoint
GEThttps://tools.moneytools.dev/v1/spf?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a detailed, recursive analysis of SPF DNS lookup chains (not just a surface-level record read) and want DMARC policy weakness detection in a single call. It is especially valuable when troubleshooting email deliverability, auditing vendor or third-party sending domains, or checking RFC compliance before deploying email infrastructure. Prefer it over generic DNS lookup tools when you specifically need the 10-lookup limit counted across nested includes.
Side effects
- Domain does not exist or has no SPF record — returns analysis with empty or missing SPF data
- Domain has no DMARC record — flagged in response but not an error
- DNS resolution timeout — may return partial results or error
- Invalid domain format in query parameter — returns validation error
- Free tier (10/day) exhausted and no payment configured — returns HTTP 402 Payment Required
