Overview

Host.io provides domain data — token-based (a missing token returns 400, verified).

Quick Start

Domain (replace YOUR_TOKEN):

curl "https://host.io/api/full/example.com?access_token=YOUR_TOKEN"
{ "error": "API Access Token Required" }

Authentication

  • Register at host.io → access token.
  • Send it as the access_token query parameter (missing → 400, verified).

Rate Limits & Notes

  • Free tier with limits (check the docs); paid plans scale.
  • Domain data.

FAQ

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

Why 400? Missing tokens return 400 (verified) — register for one.
