For agents and data tools

Ways to read the same release.

Query product variants, open a hash-bound evidence receipt, or watch approved release changes. Every interface is read-only. None of them creates new facts.

01

Query products

Use the strict REST query, the four-tool MCP endpoint, or five read-only WebMCP tools in a supporting agent browser. Unknown and conflicted evidence stays visible.

02

Verify a receipt

Each exact variant has a release-specific JSON receipt with source locators, snapshot hashes, evidence states, and a stable receipt hash.

Choose an exact variant

03

Watch releases

The JSON and RSS feeds come from one change record. They include approved public releases only.

04

Request Markdown

Send Accept: text/markdown to any human page. The response removes navigation and page decoration while keeping the released text, links, and canonical URL.

None

The MCP endpoint exposes query_products, get_evidence_receipt, calculate_product_cost, and translate_inci_label. A supporting browser sees the same jobs through five experimental WebMCP tools. Unsupported browsers ignore this optional layer. None of these tools has a model, external fetch, account, session, purchase action, or write access.
