How to call it
A starting template for Watson Natural Language Understanding. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.
# Uses OAuth. Exchange your credentials for an access token first.
curl -s "https://www.ibm.com/ENDPOINT" \
-H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
-H "Accept: application/json"This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

Watson Natural Language Understanding — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Watson Natural Language Understanding free to use?
Watson Natural Language Understanding is listed in our free catalogue, but it requires OAuth, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Watson Natural Language Understanding need an API key?
Watson Natural Language Understanding uses OAuth rather than a simple key, so you register an application and complete an authorisation flow before making calls. That is more setup than a key, and it is why OAuth APIs are harder to try quickly.
Can I call Watson Natural Language Understanding from browser JavaScript?
Not directly. Watson Natural Language Understanding did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Watson Natural Language Understanding still working?
Yes, as of 2026-09-18. Our automated check reached Watson Natural Language Understanding and recorded a 100% reliability score with a median response time of 3049 ms. We re-check on a schedule, and this page updates with the result.
Is Watson Natural Language Understanding available over HTTPS?
Yes. Watson Natural Language Understanding serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
