Sequenzy API not working for you?

  1. Sequenzy needs an API key. A 401 or 403 usually means a missing, expired or mis-sent credential: check whether it belongs in a header or the query string.
  2. A 429 response means you're being rate-limited. Slow down, cache responses, and respect any Retry-After header.
  3. If calls fail only in the browser with a CORS error, Sequenzy may not allow cross-origin requests. Call it from your server instead.
  4. If it works from one network but not another, check firewalls, VPNs and regional blocks.
  5. Check the provider's documentation, status page or social accounts for planned maintenance or a changed endpoint.

Is Sequenzy API down right now?

Sequenzy answered our last daily check (Nov 15, 2026, 13:58 UTC) in 2967 ms with HTTP 200. This page also runs a live check from our server when you open it, so you can see whether Sequenzy is responding at this moment.

How do you check whether Sequenzy API is up?

Once a day our checker requests Sequenzy's listed URL (https://docs.sequenzy.com) and records whether it answers within 15 seconds. Answers like 401 (needs a key), 403 (blocks bots) or 429 (rate-limited) count as up, because the server responded. The listed URL is often the documentation page, so an API endpoint can occasionally fail while its docs stay up.
