Overview

Tomba provides email finding/verification — key-based (an invalid key returns 400, verified).

Quick Start

Domain search (replace YOUR_KEY/YOUR_SECRET):

curl "https://api.tomba.io/v1/domain-search?domain=example.com" \
  -H "X-Tomba-Key: YOUR_KEY" \
  -H "X-Tomba-Secret: YOUR_SECRET"
{ "errors": { "type": "authentication_failed", "message": "No user found for the API supplied." } }

Authentication

  • Register at tomba.io → key + secret.
  • Send them as X-Tomba-Key/X-Tomba-Secret headers (invalid → 400, verified).

Rate Limits & Notes

  • Free tier with limits (check the docs); paid plans scale.
  • Email finder/verifier.

FAQ

Is Tomba free? Free tier with limits; more is paid.

Why 400? Invalid keys return 400 (verified) — use real keys.

What’s the auth style? X-Tomba-Key + X-Tomba-Secret headers.
