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 brasil-dados-api-email-verification-95d6fe11
```

Example prompt: Can you verify whether the email address john.doe@example.com is valid — check both the syntax and whether the domain actually has mail servers set up?

## When to prefer this

Choose this endpoint when you need both syntax validation and real DNS/MX record verification for an email address, and want a tamper-evident timestamped SHA-256 receipt as proof of the check. Prefer this over pure regex-based validators when deliverability confidence matters.

## Known failure modes

- Invalid or malformed email format returns a syntax error
- Domain with no MX records returns DNS lookup failure
- Network timeout during DNS resolution may result in an error or partial result
- Missing email path parameter returns a 400 or 404 error
- Rate limiting or payment failure returns a 402 error

## How this service works

Verify an email address: syntax check + real DNS/MX lookup. Returns timestamped SHA-256 receipt.

## Output

Returns a verification result indicating whether the email passes syntax checks and whether the domain has valid DNS/MX records, along with a timestamped SHA-256 receipt as proof of the check.
