# Agent Data API – Email Validation

> Agent Data API – Email Validation is a paid API for AI agents from agent-data-api-ui1c.onrender.com, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-14).

Validates an email address by checking its format, domain existence, and deliverability via a pay-per-call endpoint using the x402 USDC payment protocol.

## 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-api-email-validation-6d039064
```

Example prompt: Can you check whether john.doe@example.com is a valid, deliverable email address before I add it to our contact list?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call email validation check without a subscription commitment, especially inside an AI agent workflow that already handles x402 USDC micropayments. It's ideal for spot-checking individual email addresses at low cost ($0.005 per call) rather than bulk validation via a dedicated email hygiene platform.

## Known failure modes

- Missing 'address' query parameter returns a 400 Bad Request
- Malformed email string may return an invalid format error
- Payment failure via x402 protocol returns a 402 Payment Required response
- Unresolvable domain may return a domain-not-found error
- Network timeout on DNS lookup may cause a 503 or timeout error

## How this service works

Pay-per-call data services for AI agents: web extraction (text, Markdown, metadata), PDF-to-text, RSS/Atom parsing, FX and crypto prices, weather, DNS and email validation. All paid endpoints use the x402 payment protocol (USDC).

## Output

Returns a validation result for the provided email address, typically including format validity, domain existence, MX record check, and an overall deliverability assessment (e.g. valid, invalid, risky, or disposable).
