Implement REST API

[thekid]

Basic usage

Using the REST API, see https://platform.openai.com/docs/api-reference/making-requests

use util\cmd\Console;
use com\openai\rest\OpenAIEndpoint;

$ai= new OpenAIEndpoint('https://'.getenv('OPENAI_API_KEY').'@api.openai.com/v1');
$payload= [
  'model'    => 'gpt-4o-mini',
  'messages' => [['role' => 'user', 'content' => $prompt]],
];

Console::writeLine($ai->api('/chat/completions')->invoke($payload));

Streaming

The REST API can use server-sent events to stream responses, see https://platform.openai.com/docs/api-reference/streaming

use util\cmd\Console;
use com\openai\rest\OpenAIEndpoint;

$ai= new OpenAIEndpoint('https://'.getenv('OPENAI_API_KEY').'@api.openai.com/v1');
$payload= [
  'model'    => 'gpt-4o-mini',
  'messages' => [['role' => 'user', 'content' => $prompt]],
];

$stream= $ai->api('/chat/completions')->stream($payload);
foreach ($stream->deltas('content') as $delta) {
  Console::write($delta);
}
Console::writeLine();
