Rate Limits

Depending on your subscription, the finaX API enforces a request quota per rate limit window and returns headers that show your current usage.

Rate limit headers

The response includes the following headers:

• x-ratelimit (integer): Overall available requests for the current rate limit window.
• x-ratelimit-remaining (integer): Requests left for the current rate limit window.

Example values:

• x-ratelimit: 1000
• x-ratelimit-remaining: 967

In this example, your subscription allows 1000 requests in the current window, and 967 requests are still available.

cURL example

curl -X POST https://api.finax.dev/v1/xml/ubl \
  -H "X-API-KEY: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{...}' -i

Look for these headers in the response:

x-ratelimit: 1000
x-ratelimit-remaining: 967
