What it can do

As declared by the publisher

Tools · 55

  • apikeys_generate_api_key

    Generate a DataNexus API key for the given email address. Anonymous callers get 10 free lookups/week; a registered free key unlocks 100/week. Store the returned key — it is shown only once. Pass it as the X-Api-Key header on future requests. Rate limit: 3 keys per IP per 24 hours.

  • apikeys_revoke_api_key

    ⚠️ DESTRUCTIVE — requires human confirmation before use in automated pipelines. Permanently revoke a DataNexus API key. The key will stop working immediately. This action cannot be undone — generate a new key if access is needed again.

  • apikeys_rotate_api_key

    ⚠️ DESTRUCTIVE — requires human confirmation before use in automated pipelines. Revoke the current API key and issue a replacement. Returns the new key once — store it immediately. Pass keys as the X-DataNexus-Key header.
