# API Sandbox & Simulation Testing Environment

> Canonical URL: https://zainahmed.net/sandbox
> Sandbox API Endpoint: `https://zainahmed.net/api/v1/sandbox`
> Status: Active & Operational
> Isolation: Complete zero-mutation sandbox with synthetic payload echoing

## Overview
The Zain Ahmed Sandbox Environment provides developers and autonomous AI agents with a safe, zero-consequence testing surface to evaluate OpenAPI endpoints, test function calling schemas, and verify integration protocols without mutating live production records or dispatching production emails.

## Available Sandbox Endpoints

| Purpose | Method | Path | Description |
|:---|:---:|:---|:---|
| **Sandbox Status** | `GET` | `/api/v1/sandbox` | Verify sandbox availability and rate limits |
| **Payload Simulation** | `POST` | `/api/v1/sandbox` | Echo and validate structured payloads |
| **Simulated Contact** | `POST` | `/api/v1/sandbox/contact` | Test inquiry schema validation with mock tracking ID |
| **Safe Profile Read** | `GET` | `/api/v1/profile` | Query credentials without authentication walls |

## Zero Production Mutation Guarantee
All requests hitting sandbox endpoints execute strictly within isolated execution contexts. No live emails are dispatched via Resend, and no production data stores are updated.
