Authenticated legal data API
Query legal regulations, sources, jurisdictions, and product categories through a REST API, with example calls shown for `/v1/regulations` and a Playground for trying requests before using a key.
Cleo Legal Data Atlas
Cleo Legal Data Atlas is a legal data API platform for regulations, compliance data, and customs classification across 177 jurisdictions. Includes a REST API, MCP connector, and free Playground.
Overview
Cleo Legal Data Atlas is a legal data API platform that packages open legal sources into machine-readable catalogs. The homepage describes it as a REST API plus MCP connector for querying legal regulations, sources, jurisdictions, and product categories across 177 jurisdictions.
The platform is organized into three related atlas views. Legal Atlas covers cross-topic law, Product Compliance Atlas focuses on physical-product regulations, and HS Code API handles customs classification, duties, landed cost, dual-use screening, and sanctions checks in one workflow.
Core capabilities
MCP connector support
Use the MCP connector to bring the data into AI tools such as Claude or Cursor, alongside direct API access for applications and monitoring workflows.
Targeted filtering and refreshed data
Filter results by jurisdiction, product category, or enforcement body, and receive structured source data that is refreshed continuously from the catalog.
Multiple atlas views
Work with three catalog views: the cross-topic Legal Atlas, the Product Compliance Atlas for physical products, and the HS Code API for customs and trade workflows.
No-key Playground
Use the Playground to compose calls, generate curl snippets, and inspect sample JSON responses without needing an API key.
Tiered operational features
Choose a plan with monthly quotas, then scale up to webhooks, analytics, custom rate limits, SLA-backed support, and deployment options on higher tiers.
Where it fits
Legal research automation
Integrate legal lookups into a product, internal tool, or monitoring pipeline that needs machine-readable regulations and source links instead of manual research.
Product compliance checks
Use the Product Compliance Atlas to check physical products against country requirements when managing cosmetics, electronics, toys, food, apparel, or similar categories.
Cross-border trade operations
Classify goods, estimate duties and landed cost, and screen dual-use or sanctions exposure in a single customs workflow.
AI-assisted workflows
Expose the data to AI assistants or agent workflows through the MCP connector so tools like Claude or Cursor can call the catalog directly.
API evaluation and prototyping
Use the Playground and sample curl output to validate an integration idea, inspect response shapes, and compare plan fit before committing to a paid tier.
Pros and Cons
Pros
- Covers multiple legal workflows in one product family, including general law, product compliance, and customs classification.
- Offers a free Playground for evaluation before requesting an API key.
- Provides structured responses and example requests, which makes the API easier to inspect before integration.
- Publishes plan tiers and operational details such as webhooks, analytics, SLA-backed support, and DPA availability on higher plans.
Cons
- Some documentation details are only visible through the product pages and pricing copy, so the public page leaves setup and implementation specifics limited.
- The product pages note that some answers depend on plan tier, and the public FAQ does not fully spell out every quota or definition.
