# Agent Data Tools – Email Address Intelligence

> Agent Data Tools – Email Address Intelligence is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-11).

Validates an email address and returns deliverability verdict, SPF/DMARC status, disposable/role/free-provider flags, and domain existence

## Facts

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 agent-data-tools-email-address-intelligence-20b3576f
```

Example prompt: Can you check whether support@cloudflare.com is a real, deliverable email address — and tell me if it's a role address, whether the domain has SPF and DMARC set up, and if it's from a disposable or free provider?

## When to prefer this

Choose this endpoint when you need a comprehensive, single-call email intelligence check combining syntax validation, DNS/MX verification, SPF/DMARC authentication record lookup, and role/disposable/free-provider classification — all without sending a probe email. It is pay-per-call with no account required, making it ideal for lightweight agent workflows that occasionally need email hygiene checks rather than high-volume bulk validation pipelines.

## Known failure modes

- Missing 'address' query parameter returns an error
- Malformed or syntactically invalid email may return validSyntax:false with no further DNS checks
- Domain DNS lookup timeout may result in uncertain deliverability verdict
- Rate limiting or payment failure returns HTTP 402 requiring USDC payment on Base

## How this service works

Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.

## Output

A JSON object containing: the email address and domain, a deliverability verdict (e.g. 'likely-deliverable'), boolean flags for validSyntax, domainExists, acceptsMail, hasSpf, hasDmarc, disposable, roleAddress, freeProvider, and a human-readable reasons array explaining the verdict.
