NekosBest

Overview

Nekos.best serves anime images — SFW and NSFW categories — as JSON, with a deterministic hash-based randomizer. Free and keyless.

⚠️ Gotcha (verified 2026-08): requests with a generic or missing User-Agent get blocked with HTTP 403 — the API requires a descriptive User-Agent (their docs specify the format, e.g. <app-name>/<version>). Send a proper UA like curl -A "my-app/1.0".

Quick Start

Random neko image (use a descriptive UA!):

curl -A "my-app/1.0" "https://nekos.best/api/v2/neko?amount=1"

{
  "results": [
    {
      "url": "https://nekos.best/api/v2/neko/0001.png",
      "artist_name": "...",
      "artist_href": "https://...",
      "source_url": "https://..."
    }
  ]
}

Other categories:

curl -A "my-app/1.0" "https://nekos.best/api/v2/hug?amount=1"
curl -A "my-app/1.0" "https://nekos.best/api/v2/kiss?amount=1"

Authentication

None — keyless. But the User-Agent must be descriptive (403 otherwise, verified).
