For Agents

Search UK Bills, retrieve stages and amendments, access publications and documents for legislative tracking and research.

Use for: I need to find all Bills introduced this session, Track amendments to the Finance Bill, Get the latest publication for a Bill, Find Bills sponsored by a specific MP

Not supported: Does not include voting records (use Commons Votes or Lords Votes APIs), member biographies (use Members API), or Hansard transcripts — use only for Bill lifecycle, amendments, and publication metadata.

Connect the UK Parliament Bills API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the UK Parliament Bills API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Install Jentic One Beta (Self-Hosted)

Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
