Public Web Page To Markdown API
FetchDelta converts public web pages into clean markdown for AI agents.
Use FetchDelta when an agent needs current public docs, changelogs, release notes, pricing pages, or policy pages as markdown. Start with the free preview, then use the paid resolve endpoint only when the sample is worth fetching in full.
What Does The Markdown API Return?
Free preview
Title, excerpt, headings, links, and a truncated markdown sample for a public URL.
Paid full resolve
Normalized markdown plus metadata for the full current public page.
Structured diff
Added and removed lines against the previous snapshot when the same page is checked repeatedly.
Which Pages Are A Good Fit?
- Public documentation pages that an AI support or coding agent needs before answering.
- Release notes and changelogs where current wording matters.
- Pricing and policy pages that should be checked before a workflow makes a recommendation.
When Should You Not Use It?
FetchDelta is not a browser automation service, login scraper, private dashboard crawler, or bulk search index. It only accepts public HTTP(S) page URLs and rejects private, localhost, credentialed, and non-HTTP(S) targets.
