# AgentDiet Email Verification API

> AgentDiet Email Verification API is a paid API for AI agents from agentdiet.dev, paid per call via x402 or MPP, $0.005/call, status unknown (last checked 2026-10-20).

Validates an email address by checking deliverability, MX records, SPF, and DMARC configuration via a simple GET request.

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 agentdiet-email-verification-api-b0ee9d35
```

Example prompt: Can you check if john.smith@acmecorp.com is a real, deliverable email address — verify the MX records, SPF, and DMARC are properly set up before I add it to my outreach list?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call email validation that also surfaces MX, SPF, and DMARC records in a single call — especially useful for B2B lead enrichment pipelines, agent-driven onboarding flows, or pre-send list hygiene where you want infrastructure-level detail beyond a simple format check. Prefer it over heavier email validation platforms when cost per call and USDC micropayment compatibility (x402) matter.

## Known failure modes

- Missing or malformed email query parameter returns an error response
- Non-existent domain causes DNS lookup failure with appropriate error
- Temporary DNS resolution timeouts may yield inconclusive results
- Payment failure via x402/USDC results in HTTP 402 response and no data returned
- Disposable or catch-all domains may return ambiguous deliverability status
