Webpage to JSON for AI Agents
A web-to-JSON structured data extraction tool on the Apify platform. It accepts a URL and natural-language field instructions, and outputs JSON data with type declarations and citations to evidence in the source text. It supports invocation by agents through MCP.
Timeline (last 90 days)
Webpage to JSON for AI Agents is a tool offered on the Apify platform that takes a URL and natural-language field requirements as input and returns JSON with type declarations, with each value accompanied by a verbatim quote from the page.
The tool's output includes a data field (structured data), an evidence field (the source text for each value), and an unverifiedFields array (flagging fields for which no source-text basis can be found).
In the official example, the input instruction is to extract the book title, price, currency code, and stock status, the target page is a book detail page on books.toscrape.com, and the output data is the title 'A Light in the Attic', price 51.77, currency code GBP, and stock status true.
The tool offers an extractionSchema option that allows passing in a JSON Schema to specify the exact output structure.
The tool offers a listMode option; when set to true, it can extract multiple records at once from pages containing multiple records, such as product listing pages or job boards.
The requireEvidence option is enabled by default, and any value lacking a source-text quote is placed into unverifiedFields.
The tool can be invoked via Apify's Python client: pass a token to create a client, call the corresponding Actor, pass the URL and instruction, then iterate over the dataset and print the data field of each result.
The tool costs $0.03 per page from which data is successfully extracted; pages where no data is found are not charged, and LLM costs are included.
Such tools cannot fully replace custom crawlers; effectiveness may be reduced for pages with extremely complex structures or that require login state or dynamic rendering, and they are better suited to rapid validation, low-frequency data collection, and data verification scenarios that require an evidence chain.
