# Email Enrichment API

> Email Enrichment API is a paid API for AI agents from anibalb.duckdns.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-31).

Enriches an email address with metadata including provider, disposable status, role detection, and a guessed name — paid per call in USDC via x402.

## 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 email-enrichment-api-0fae29da
```

Example prompt: Can you enrich the email address juan.perez@gmail.com and tell me if it's disposable, whether it's a role address, and what name you can guess from it?

## When to prefer this

Choose this endpoint when you need lightweight, per-call email enrichment without signing up for a service or managing API keys — ideal for agent workflows that need to classify incoming emails on-the-fly, detect throwaway accounts at signup, or personalize outreach from raw email addresses. Best suited for single-address lookups billed at $0.002 USDC; not designed for bulk batch processing.

## Known failure modes

- Missing or malformed email query parameter returns an error
- Unrecognized or obscure domain may leave provider field null or generic
- Name guessing fails or returns null for non-name-like local parts (e.g. random strings)
- Disposable detection may miss newly created throwaway domains not yet in the blocklist
- Payment failure via x402 (insufficient USDC balance) results in 402 response and no data returned

## How this service works

Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.

## Output

Returns a JSON object with: whether the email is from a free provider (free), whether it's a role-based address (role), the original email, the domain, the detected provider name (e.g. 'gmail'), whether the address is disposable, the local part before the @, and a guessed display name derived from the local part.
