# AgentFeed Email Verify

> AgentFeed Email Verify is a paid API for AI agents from x402.ochinimus.app, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-15).

Validates an email address by checking syntax, DNS/MX records, disposable-domain status, and role-account classification, then returns a deliverability verdict

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 agentfeed-email-verify-118a1352
```

Example prompt: Can you check whether jane.doe@gmail.com is a valid, deliverable email address — tell me if it passes syntax and DNS checks, and whether it looks like a disposable or role account?

## When to prefer this

Choose this endpoint when you need lightweight, fast email validation covering syntax, DNS/MX, disposable-domain detection, and role-account classification without sending a probe email. It is pay-per-call with no API key required (x402 payment or prepaid balance), making it ideal for agents that validate sporadically or in bursts. Prefer it over full SMTP-probe services when you want speed and privacy, and over simple regex checks when you need DNS and disposable-domain intelligence.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Email longer than 254 characters rejected
- Network/DNS lookup failure may degrade MX check results
- Disposable domain list may lag newly created throwaway domains
- No SMTP probe performed, so deliverable_likely does not confirm mailbox existence
- Payment failure (x402) blocks the request if neither x402 nor prepaid key is provided

## How this service works

Email verification: syntax, MX, disposable-domain, role-account and free-provider checks with a deliverable_likely, risky or undeliverable verdict and its reasons. Use when you need to answer: Can this email address plausibly receive mail? No SMTP probe.

## Output

Returns a JSON object with: the input email, a verdict string (e.g. 'deliverable_likely'), individual check results (syntax validity, MX records with priorities, disposable-domain flag with list fetch timestamp, role-account classification, free-provider flag), an array of reasons influencing the verdict, a note about SMTP probe limitations, and the data source attribution.
