# SPF Authorizes Proofpoint Checker

> SPF Authorizes Proofpoint Checker is a paid API for AI agents from email.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-24).

Checks whether a domain's SPF record explicitly authorizes Proofpoint to send email on its behalf, returning yes/no, the matching mechanism, and the full SPF record.

## 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-authorizes-proofpoint-checker-702cd8ea
```

Example prompt: Check if example.com's SPF record authorizes Proofpoint to send its email — I want to know whether Proofpoint is listed as an allowed sender and what the full SPF record says.

## When to prefer this

Use this endpoint when you need to specifically verify Proofpoint's authorization in a domain's SPF record — for confirming vendor email integrations are correctly wired for deliverability, auditing for unexpected Proofpoint configurations, or pre-launch deliverability checks. Prefer over a general SPF lookup when Proofpoint is the target sender to verify.

## Known failure modes

- Domain has no SPF TXT record — returns no match
- Domain does not exist or is unresolvable — DNS lookup failure
- SPF record exists but contains no Proofpoint-related mechanisms — returns 'no' with the full record
- Cloudflare DoH service unavailable — lookup timeout or error
- Malformed SPF record that cannot be parsed

## How this service works

Does the domain's SPF record authorise proofpoint to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for proofpoint's include/ip mechanisms, returning yes/no, the matching mechanism and the full record. Confirms a vendor integration is wired for deliverability, or spots an unexpected sender. $0.01 per lookup.

## Output

Returns a yes/no authorization result indicating whether Proofpoint is authorized in the domain's SPF record, the specific SPF mechanism (include or IP) that matched, and the complete SPF TXT record retrieved via Cloudflare DNS over HTTPS.
