Complete PHP Example

helix-ai-image-generation.php

<?php
$url = "https://ai-image-gen-by-helix-api.p.rapidapi.com/generate";
$payload = json_encode({"prompt": "A futuristic city skyline at sunset, digital art", "width": 512, "height": 512});

$ch = curl_init($url);
curl_setopt_array($ch, [
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $payload,
    CURLOPT_HTTPHEADER => [
        "Content-Type: application/json",
        "X-RapidAPI-Key: YOUR_API_KEY",
        "X-RapidAPI-Host: ai-image-gen-by-helix-api.p.rapidapi.com"
    ]
]);

$response = curl_exec($ch);
curl_close($ch);

$data = json_decode($response, true);
echo "Status: " . $data["status"] . "\n";
echo "Result: " . print_r($data["data"], true) . "\n";

Response Format

All Helix-API endpoints return a consistent JSON envelope:

{
  "status": "ok",
  "data": { ... },
  "meta": {
    "request_id": "req_abc123",
    "latency_ms": 42
  }
}

On errors, status becomes "error" and a message field explains what went wrong.

Error Handling

Status	Meaning	Action
`200`	Success	Parse the response body normally
`400`	Bad request	Check your request parameters
`401`	Unauthorized	Verify your X-RapidAPI-Key header
`429`	Rate limited	Wait and retry with exponential backoff
`500`	Server error	Retry after a short delay
