> SPF Authorizes Zoho 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).

## 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-zoho-checker-99b27800
```

Example prompt: Check whether example.com's SPF record authorizes Zoho to send email on its behalf — I want to know if Zoho is listed, which mechanism matches, and what the full SPF record looks like.

## When to prefer this

Use this endpoint when you need a fast, single-vendor-specific SPF check for Zoho rather than a full SPF parse. Ideal for confirming Zoho Mail deliverability configuration, auditing whether Zoho is an authorized sender for a client domain, or spotting unexpected Zoho authorization on a domain. Prefer this over generic SPF parsers when the question is specifically 'is Zoho authorized?' and you want a structured yes/no answer with mechanism detail.

## Known failure modes

- Domain has no SPF TXT record — returns no authorization with empty record
- Domain not found or DNS resolution failure via Cloudflare DoH
- SPF record is malformed or exceeds DNS lookup limit
- No query parameter provided for the domain — request error
- Rate limiting or payment failure for the $0.01 per-call fee

## How this service works

Does the domain's SPF record authorise zoho to send its mail? Reads the SPF TXT record (Cloudflare DoH) and checks for zoho'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 flag indicating whether Zoho is permitted by the domain's SPF record, the specific SPF mechanism that matched (e.g. include:zoho.com), and the full raw SPF TXT record retrieved via Cloudflare DNS-over-HTTPS.
