Response time matters in AI chat experiences. Users expect near-instant replies, and every millisecond you add to the response pipeline increases the chance they’ll notice a delay. Since ChatAds sits between your LLM call and the final response, we’ve designed the API to be as fast as possible — but there are ways to make it even faster depending on your use case.

​
Optimization Checklist

​
1. Add a timeout to your ChatAds call

If you’d rather show no ad than wait too long, wrap the API call in a timeout. This way your chat response is never blocked — if ChatAds doesn’t respond in time, you simply skip the affiliate link. 
const controller = new AbortController();
const timeout = setTimeout(() => controller.abort(), 500);

try {
  const response = await fetch("https://api.getchatads.com/v1/chatads/messages", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "x-api-key": "YOUR_API_KEY",
    },
    body: JSON.stringify({ message: aiResponse }),
    signal: controller.signal,
  });
  clearTimeout(timeout);
  const data = await response.json();
  // Insert affiliate link into response
} catch (err) {
  // Timed out — send the response without an affiliate link
}

​
2. Call ChatAds in parallel

If you’re doing any post-processing after the LLM responds — formatting, safety checks, logging — fire the ChatAds call at the same time. The latency overlaps instead of stacking, so ChatAds adds zero perceived delay. 
const llmResponse = await openai.chat.completions.create({ ... });

// Run ChatAds and your other post-processing in parallel
const [chatadsResult, formattedResponse] = await Promise.all([
  fetch("https://api.getchatads.com/v1/chatads/messages", {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "x-api-key": "YOUR_API_KEY",
    },
    body: JSON.stringify({ message: llmResponse.choices[0].message.content }),
  }).then(r => r.json()),

  formatAndSanitize(llmResponse),
]);

// Insert affiliate link if available
if (chatadsResult.data?.offers?.length) {
  const offer = chatadsResult.data.offers[0];
  formattedResponse = formattedResponse.replace(
    offer.link_text,
    `<a href="${offer.url}">${offer.link_text}</a>`
  );
}
