Use another supported https://www.gov.uk/... URL to create a custom watch (the example is already part of the fixed watchlist). List watches with GET /v1/watches; remove one with DELETE /v1/watches?url=ENCODED_URL. Check its records with GET /v1/history?url=ENCODED_URL or GET /v1/changes?url=ENCODED_URL.
Inspect current guidance
curl -X POST 'https://uk-source-intelligence.pages.dev/v1/inspect' -H 'Authorization: Bearer YOUR_API_KEY' -H 'Content-Type: application/json' -d '{"url":"https://www.gov.uk/vat-rates"}'
Limitations: GOV.UK Content API rendered fields only. No PDFs, linked attachments, legal interpretation or general web monitoring. Saved change histories begin when first polled. Customer checks use a fair scheduled queue; 15 minutes is a poll cycle, not a guaranteed per-page interval. Only paid customers authorised for card purchases should start paid checkout; an agent must not purchase without its owner's permission.
