The NeLocker API

Pull from the largest library of free AI prompts straight into your app, custom GPT, agent, or tool. Read-only, public, free — no key needed for reads. Build on it.

Base URL

https://nelocker.com/api/v1

Read-only (GET) · JSON · rate-limited per IP · responses are cacheable. Every prompt carries its license (CC0 / MIT / original) — preserve attribution for CC0 & MIT.

Endpoints

GET /prompts ?tool= &category= &q= &sort=top|new &page= &limit= (max 50)

GET /prompts/{id} — one prompt

GET /tools — tools + categories

GET /search ?q= (2–100 chars)

A prompt looks like

{
  "id": "…",
  "title": "Cold email that gets a reply",
  "description": "…",
  "body": "You are a concise sales writer…",
  "tags": ["email", "sales"],
  "license": "CC0-1.0",
  "source_name": "…",
  "community": false,
  "author_name": null
}

That's the whole shape — only public prompt fields. No user data, ever.

Connectors

Use NeLocker prompts right where you work: an MCP server for Claude, a Custom GPT for ChatGPT, and a browser extension to drop prompts into any chat box. (Rolling out — built on this API.)
