Question

Accepted Answer

Ka gina AI a cikin app ta hanyar kira ta API na model a gefen **wajen samaniya** da kuma jiyya fiton sa a matsayin input marar aminci. Ga Claude, wannan yana nufin kira da **Messages API** daga barkacin ku (PHP, don WordPress plugin) tare da API key da aka rijayi a wajen samaniya — babu tayin JavaScript na gida, inda kowa zai iya sace shi.

## Karanten gefen samaniya

Dokar mahimmanci: **API key yana rayuwa a wajen samaniya**. Browser yana magana da *naka* endpoint; *naka* endpoint yana magana da Claude.

```php
<?php
// In a WordPress plugin: run this in PHP (server-side), never expose the key to JS.
$resp = wp_remote_post( 'https://api.anthropic.com/v1/messages', [
  'headers' => [
    'x-api-key'         => getenv( 'ANTHROPIC_API_KEY' ), // from env/secret store, not code
    'anthropic-version' => '2023-06-01',
    'content-type'      => 'application/json',
  ],
  'timeout' => 30,
  'body' => wp_json_encode( [
    'model'      => 'claude-sonnet-4-5',   // pick a current model id
    'max_tokens' => 1024,                   // cap output → controls cost
    'messages'   => [
      [ 'role' => 'user', 'content' => $user_prompt ],
    ],
  ] ),
] );

if ( is_wp_error( $resp ) ) { /* handle network/timeout errors, maybe retry */ }
$data = json_decode( wp_remote_retrieve_body( $resp ), true );
$text = $data['content'][0]['text'] ?? '';   // validate before trusting/displaying it
```

## Bayan ainihi

```text
- TOOL USE / FUNCTION CALLING → let the model call your functions (search, DB lookup)
- STREAMING                   → stream tokens for a responsive UI on long answers
- PROMPT CACHING              → cache a large static system prompt → cheaper, faster
- STRUCTURED OUTPUT           → ask for JSON, then parse + schema-validate it
- ERRORS & RATE LIMITS        → handle 429/5xx with backoff + retry; show a fallback
- COST                        → cap max_tokens, log token usage, set per-user limits
```

Koda yaushe **tabbatar da fiton model kafin amfani da shi**: babu tayin aiki a matsayin code, yi imani ba tare da ɓoye ba, ko rubuta shi a DB ku ba tare da jira. Model ɗin jiya gina jarrumar rubutu mai iko amma mai kuɗa, ba tushen aminci.

## Me ya sa shi mahimmanci
