Query international treaties laid before Parliament, track CRaG scrutiny periods, and retrieve committee reports across 6 endpoints.

Connect the UK Parliament Treaties API to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the UK Parliament Treaties 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.

Time to first call

Direct integration: 2-3 days mapping 6 endpoints, handling CRaG periods, and parsing committee reports. Through Jentic: under 20 minutes — search by intent, load schema, execute.

FAQs

Specific to using UK Parliament Treaties API API through Jentic.

What is CRaG and how does it relate to treaty scrutiny?

The Constitutional Reform and Governance Act 2010 (CRaG) requires the government to lay treaties before Parliament for 21 sitting days before ratification. During this period, either House can vote to reject ratification. The API tracks CRaG scrutiny periods, deadlines, and parliamentary objections.

Can I filter treaties by government department?

Yes. Use GET /api/Treaties/Search with department parameters to filter treaties by the responsible government department (typically the Foreign Office, but also Trade, Defense, or other departments depending on treaty subject). This helps track departmental treaty activity.

How do I find treaties related to a specific policy area?

Use the subject filter in GET /api/Treaties/Search to retrieve treaties in specific policy areas such as trade, defense, environment, or human rights. The API categorizes treaties by subject to support policy-focused research.

What is a command paper number?

A command paper is a document laid before Parliament by a minister, including treaty texts. Command papers have unique reference numbers (e.g., Cm 1234) used to identify treaties. The API allows searching by command paper number.

Is authentication required for this API?

No. The UK Parliament Treaties API is a public API with no authentication required. It provides open access to treaty data for research, policy analysis, and monitoring purposes.

Where does Jentic's OpenAPI spec for this API come from?

Jentic imports and validates the official Swagger spec published by UK Parliament at https://treaties-api.parliament.uk/swagger/v1/swagger.json, converts it to OpenAPI 3.0.3, and keeps it updated so AI agents and developers can call the API via structured tooling.
