# SPF Record Check

> SPF Record Check is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches and fully parses a domain's SPF record, counting DNS lookups, expanding includes, flagging duplicates and common misconfigurations for email deliverability audits.

## Facts

- Endpoint: GET https://intel.rallylive.ca/email/spf
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability spf-record-check-19abfac5
```

Example prompt: Can you check the SPF record for example.com and tell me if it has any misconfigurations, whether it exceeds the 10-DNS-lookup limit, and if there are any duplicate records?

## When to prefer this

Use this endpoint when you need a detailed, structured audit of a domain's SPF configuration — especially when diagnosing deliverability issues, verifying anti-spoofing posture, or checking DNS lookup depth. Prefer it over generic DNS lookup tools when you need SPF-specific parsing (include expansion, lookup counting, qualifier analysis) in a single call at low cost ($0.01). Pair with the sibling email-deliverability-report endpoint if you also need DMARC/DKIM in the same request.

## Known failure modes

- Domain has no SPF record — returns empty or not-found result
- Domain does not exist or DNS resolution fails — DNS error returned
- SPF record is malformed beyond basic parsing — partial parse with error flags
- Rate limiting or network timeout reaching authoritative DNS — error response
- Invalid domain input format — validation error

## How this service works

SPF record check for a domain: fetches and parses the SPF record (all qualifier, includes, ip4/ip6, a, mx, redirect), counts DNS-lookup mechanisms against the 10-lookup limit by expanding includes, flags duplicate records and common errors. Email deliverability and anti-spoofing audits. $0.01 per domain.

## Output

Returns a parsed breakdown of the domain's SPF record including the all-qualifier setting, list of include mechanisms, ip4/ip6 ranges, a and mx directives, redirect targets, total DNS lookup count versus the 10-lookup limit, flags for duplicate SPF records, and identified common errors or misconfigurations.
