# MoneyTools SPF & DMARC Analyzer

> MoneyTools SPF & DMARC Analyzer is a paid API for AI agents from tools.moneytools.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-11-05).

Recursively expands SPF includes, counts DNS lookups against the RFC 10-lookup limit, and flags weak or missing DMARC policies for a given domain

## Facts

- Endpoint: GET https://tools.moneytools.dev/v1/spf?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown

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 moneytools-spf-dmarc-analyzer-f93a2420
```

Example prompt: Can you check if github.com has any SPF or DMARC issues — specifically whether the SPF record exceeds the 10 DNS lookup limit or uses a weak policy like +all?

## When to prefer this

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.

## Known failure modes

- 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

## 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).
