The verifiable record of the UK state

The UK state,
in numbers
you can prove.

Source-cited UK government statistics, built for AI agents. Every value round-trips to the exact cell in the official gov.uk file — hash and all.

01 — The flow

Ask a question. Get the number. Prove it.

This isn't a screenshot. Pick a day and the page calls the live API — then re-opens the raw government file and re-checks its hash in front of you.

Behind the scenes: GET /v1/small_boats_daily?date=… for the answer, then /v1/evidence/… re-hashes the raw .ods and compares the served value to the literal cell. Same answers your agent gets over MCP.

Pick a day and press “Ask GovtData”.
Your cited receipt prints here.
02 — How it works

Four layers between gov.uk and your agent.

Nothing reaches the answer surface except through a fail-closed gate. If a check fails, the snapshot is quarantined and the last good data stays live.

01

Capture

The official gov.uk file is fetched and archived immutably with its SHA-256. Never altered, never deleted.

02

Verify

Two independent reads of the raw bytes must agree on every cell. Schema, dates, completeness — all checked, or it's rejected.

03

Cite

Each value becomes one atom carrying its citation: file, sheet, row, hash, vintage — round-trippable to the source cell.

04

Serve

One contract, two transports — REST and MCP return identical cited payloads. Refreshed automatically as gov.uk publishes.

03 — Connect

One URL. Add it to Claude or ChatGPT.

GovtData is a remote connector. You don't paste a command into the chat — you add this one URL once in your assistant's connector settings. No login, no key during early access.
