1. Check UKSI-observed GOV.UK changes
For questions such as "What wording changed on this HMRC page since it was first monitored?", start with the free, read-only change brief. It covers one fixed public HMRC example (SALF1480). A free response may legitimately have no changes yet. Do not interpret this as proof that the underlying GOV.UK page never changed.
curl -sS 'https://uk-source-intelligence.pages.dev/v1/change-brief'
Read changes for retained before-and-after text, fingerprints and observation dates when available. Read insufficient_history for pages with no comparable versions and inconclusive for records that cannot safely be compared. last_observed_at means a check occurred; it is not the time HMRC edited the page.
Agent tool: connect to our MCP gateway and call get_govuk_change_brief. Without a key it returns the same free one-page scope. With a valid trial or paid key, it covers the nine fixed monitored pages plus URLs watched by that key. Use a private bearer key in client settings; never publish it in prompts or logs.
Choose the right tool: For the current official position, read GOV.UK directly. For UKSI-retained prior wording, use the change brief or authenticated page_history / page_changes. The basic VAT source preview below is for live source/quote inspection, not historical evidence.
Limits: History starts with the first successful UKSI observation. Only selected GOV.UK Content API text is covered; changes between polling intervals can be missed. Comparisons use the latest two distinct retained versions, not a certified event-by-event audit trail. PDF and attachment bodies, legal interpretation and guaranteed detection are not included. A three-day free trial may establish only a baseline if no wording changes during that period. Any paid purchase requires human approval.
Live free preview · No API key
Check official GOV.UK VAT source evidence
Open the free live evidence demo. It retrieves an official GOV.UK VAT page, checks example wording and returns a SHA-256 source fingerprint. This is a live source check, not a retrospective change report.
AI agents: Connect to MCP endpoint and call preview_source_evidence without a key. For evidence and monitoring on your own supported GOV.UK page, call start_free_trial: 3 days, 10 requests per UTC day, 1 custom watched page, subject to abuse limits and availability. Paid access is £9 once for 30 days and requires the human operator to approve payment.
Free trial: POST /v1/trial, save the returned API key (shown once). Paid: POST /v1/checkout, complete card payment via Stripe and return to /success for instant activation.
Send Authorization: Bearer YOUR_API_KEY with each protected request. Trial: 3 days, 10 calls/day, 1 custom monitored GOV.UK URL. Paid: £9 once for 30 days, 100 calls/day, 3 custom monitored URLs.
Monitor your own GOV.UK page
curl -X POST 'https://uk-source-intelligence.pages.dev/v1/watches' -H 'Authorization: Bearer YOUR_API_KEY' -H 'Content-Type: application/json' -d '{"url":"https://www.gov.uk/vat-rates"}'
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.
