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.
Example use cases
Detect throwaway signup emails
“I'm getting a lot of signups with suspicious email addresses — can you check if user@tempmail.org is a disposable or throwaway email before I let them into my platform?”
Identify corporate vs free email
“Can you tell me whether the email contact@acmecorp.com is from a free provider like Gmail or a real corporate domain, and whether it looks like a role-based address?”
Guess user name from email
“I have a lead's email address, m.johnson@outlook.com — can you enrich it and give me a best-guess first and last name so I can personalize my outreach?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/email-enrichment?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
