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